IEC C14 Appliance Inlet with High-Performance Filter
For applications that require particularly high interference immunity, Schurter is launching the new high-performance filters of the 5124 series. With identical dimensions to the proven 5120 and 5123 series, both symmetrical and asymmetrical interference signals can be attenuated even better with the 5124 series, thanks to the use of high-performance components.
The 5124 series combines an IEC C14 appliance inlet with a high-performance mains filter. Thanks to a wide metal flange, the housing makes contact over a large area, which guarantees an optimal filter and shielding effect.
High-Performance Filter:
The exclusive chokes with high-permeable toroidal cores of the 5124 series have an inductance that is many times higher than that of the standard 5120 series. This results in an attenuation of asymmetrical interference signals that is around 10 dB higher. Massively enlarged X-capacitors help gainst symmetrical interference. Despite significantly larger components, the dimensions of the 5124 predecessor’s series have been retained.
Identical Dimensions
The 5124 series is available in standard or medical versions. It makes sense to use it where a particularly high attenuation is necessary and the filter effect of a 5120 or even 5123 series is no longer sufficient. Thanks to identical dimensions, the optimal series can be selected - depending on the interference level - without any design changes. The appliance filters are, of course, equipped with the well-proven V-Lock cord retention system.
Performance and Approvals
The 5124 series is certified for currents up to 10 A/250 VAC according to IEC and 15 A according to UL/CSA at 125/250 VAC. It features ENEC, CQC as well as cURus approvals.

Data centers are handling and analyzing enormous amounts of information daily. As data generation increases, the heat generated by the data center indispensably increases. This excess heat generated by data centers can harm the hardware including Central Processing Unit (CPUs) and Graphic Processing Unit (GPUs), reducing their performances, or causing complete failures. To ensure optimal operation, it is crucial to select the right cooling solution.
Market Trends:
According to the (Technavio report 2023), the global market for cooling data centers is projected to increase from USD9.5 billion in 2020 to USD22.6 billion by 2025, with a Compound Annual Growth Rate (CAGR) of 18.0%. However, the high energy consumption associated with data center cooling contributes to increased carbon emissions and energy costs. Therefore, businesses are seeking eco-friendly and energy-efficient cooling technologies, such as free cooling, liquid cooling, and artificial intelligence (AI).
Free Cooling:
One of the most popular methods for cooling data centers is free cooling, which utilizes outer air to cool the center, as opposed to traditional air conditioning. However, technology is not suitable for all climates. For instance, in humid areas, free cooling may cause condensation that damages the hardware or necessitates additional cooling during warmer periods.
Liquid Cooling:
Liquid cooling is gaining popularity in data centers due to its efficiency. Liquid coolant is used to remove heat from the hardware, as liquids offer higher thermal capacity than air resulting in reduced energy consumption. Additionally, liquid cooling fans are quieter than traditional air-cooled fans. As a result, many data centers are turning to this technology to improve their cooling efficiency.
Liquid cooling systems can be classified into two types, namely direct and indirect. Direct liquid cooling involves direct contact between the liquid and hardware, removing heat directly from the source. On the other hand, indirect liquid cooling uses the liquid to cool a heat exchanger, which draws heat from the hardware. Although direct liquid cooling is more effective in removing heat directly from the source compared to indirect liquid cooling, it may require a higher implementation and maintenance cost.
AI-Based Cooling:
AI-based cooling systems utilize sensors to analyze data and optimize temperature and humidity levels within data centers. Furthermore, the systems can predict and prevent potential cooling issues. Implementing AI-based cooling system can reduce energy consumption and enhance cooling efficiency. However, it may involve significant upfront cost and ongoing AI Algorithms development to ensure the accuracy of the real-time data.
In Conclusion, selecting the appropriate cooling solution based on business needs is vital for data centers to ensure optimal performance, reduce energy consumption, and minimize the risk of hardware damage and downtime.

General Use Of Microswitches:
Microswitches have become indispensable in the sensing and control industry for controlling electrical signals. With years of experience, Johnson Electric has supplied billions of microswitches used in home appliances, industrial equipment, automotive applications, agricultural machinery, and control systems worldwide. In most applications, the requirements for the switches are quite simple: they consist of at least two contacts, a common contact with either a normally open contact or a normally closed contact, connected to a snap-action mechanism to switch between the contacts and turn devices on and off. While these switches can operate safely and reliably in general applications, they have limited capabilities in various harsh environments. For this reason, sealed microswitches emerged as a viable solution. Sealed microswitches are basically the same as un-sealed microswitches with the addition of a protection against dust or moisture to enter the switch and reach the contact system.
Microswitches in Home, Industrial, or Automotive Applications:
The requirements for switches, however, can be extremely demanding in environments with high humidity, such as certain household appliances (dishwashers, coffee machines, etc.) or in industrial and automotive applications. Besides water, oil and dust can have a major impact on the applications, sudden temperature changes can also affect the proper functioning. It requires a high degree of sealing to ensure that the switches work without any problems. For example, this sealing should not only withstand the standard temperature range of -40°C to +85°C, but also function at higher temperatures or unexpected temperature drops. These specific applications therefore require a balanced and customized solution in sealing technology, regarding materials, switch- and seal design.
Sealing Technology:
To achieve sealing against dust or water, a "flexible" membrane must be fitted on all switch parts that have an open connection between the internal mechanism of the switch and the outside world. Such parts may be the plunger, the housing parts, or the terminal outputs. In the case of the plunger, the membrane must be flexible; in other areas, a more rigid seal may be sufficient. Consequently, for the microswitch to be manufactured properly and to ensure its function for a long time in harsh environment, the choice of sealing materials is crucial. Adding a seal to a microswitch affects its operating characteristics. In the case of the plunger, adding a seal usually increases the operating force. On the terminals, the seal can limit the soldering time to prevent overheating.
To provide a high-quality seal, Johnson Electric uses either a seal ring mounted separately on the plunger or twin-shot technology to provide housing parts with built-in seals. Different technologies are used for the housing parts and terminals. For example, either by ultrasonic welding of housing parts or by applying a special glue. By applying these solutions, the microswitches can be qualified with the IP67 degree of protection. When open terminals are used, IP protection is limited to the top or plunger side.
Johnson Electric Offer:
Johnson Electric's qualified switches are used to accurately detect the position of mechanical components in industrial and household applications. Additionally, to ensure 360-degree protection of the microswitch, Johnson Electric offers the option of adding moisture protection on the terminal side with lead wires soldered to the switch terminals. These lead wires are then routed through a cable box and potted to ensure IP67 protection on the terminal side. If the switch is UL approved the wires must also be UL approved. The final microswitch product is an IP67-protected switch with an operating temperature range between -40°C and +85°C according to UL61058 and even up to +125°C on demand.
Sealed switches are available in a wide range of sizes and ratings. The most common series are L16, V4NS, F1NS, V3S, 4BR, V9N and TS sealed switch families. Except for the TS, all other switches can be supplied with regular levers or terminals. All mentioned switch families have a UL or/and ENEC approval.
Conclusion:
Johnson Electric can offer you a complete program of sealed switches. The features of these switches include compact size, high lifetime, a high level of protection, and increased electrical properties, etc. There are different types of microswitches, but their selection depends on the requirement. To support you with the correct switch selection please contact our sales department for more information.
