Sensata | Crydom offers an extensive line of DIN Rail mount Solid State Relays and Contactors to suit a broad range of market needs. DIN rail has become very common on industrial panels and cabinets, which makes DIN Rail mount one of the main mounting styles for industrial devices.
Our DIN Rail mount AC output solid state relays and contactors are available in single, dual, 3-phase and 4 channel configurations with ratings from 2 to 75 Amps per channel at 24 to 660 VAC and motor ratings of up to 5 HP at 480 VAC.
Housing width varies from 6mm for the lowest rated DIN rail AC solid state relay, up to 54mm for the 4 channel version. These DIN rail AC SSRs don’t require additional heat sinking, which makes them “ready-to-use”.

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.

Magnet wire solutions from TE Connectivity deliver high-quality, cost-efficient, and clean terminations for motor, coil, solenoid, and other magnet wire applications. Solutions are available to terminate copper wire, aluminum wire or a combination of both.
MAG-MATE and SIAMEZE terminals are based on insulation displacement contact (IDC) technology, while AMPLIVAR products terminate magnet wire through crimp compression. For compressor applications, TE also offers cluster block connectors designed for terminating hermetic header pins.
These magnet wire solutions eliminate the need for pre-stripping and soldering of magnet wire, resulting in a highly repeatable and automatable termination process.
MAG-MATE Terminals
Insulation displacement contact (IDC) terminals available in poke-in, poke-in tab, splice, crimp wire barrel, solder post, quick connect tab, pin, and receptacle styles. Standard MAG-MATE terminals accept 34-11AWG magnet wire.
AMPLIVAR Terminals & Splices
Crimp terminals and splices with a unique wire barrel design featuring serrations and burrs that displace magnet wire insulation without wire stripping. AMPLIVAR products are designed to terminate magnet wire to itself or in combination with solid or stranded lead wire.
SIAMEZE Terminals
Compact IDC terminals for interconnecting magnet wires, lead wires and other components in space limited systems. The terminal is available with a moving beam contact that accepts a wide range of wire sizes in a single part.
Cluster Blocks
Fully insulated, one piece housing connectors that allow electrical connection of sealed hermetic header pins on compressors. These connectors only accept pins from one side, preventing reversed polarity connections.

New Generation of Mechanical Pushbuttons made of High-Quality Stainless Steel
The MSM push-button family has been successfully used on the market for over 30 years. It is known for its durability, precision and particularly high-quality workmanship. These characteristics - combined with additional features - distinguish the new MSM II generation to the same extent.
Expanded Standard Portfolio
A large number of variants have been included in the standard portfolio. For example, the new point illumination. In addition to point illumination, this also applies to the ring and area illumination variants, which are available in a wide variety of lighting colours. Here, the customer is spoilt for choice. There is a choice of different colours as well as RGB versions that allow individual settings and light scenes.
All lighting variants are available for operation on a 5, 12 or 24 VDC supply voltage.
Improved Features:
The MSM II family has not only improved in appearance, but also in technical features. The most important are:
Subminiature Microswitch
The familiar MSM push-button with microswitch and switching currents from 100 mA to 10 A is now joined by a subminiature microswitch. This has been made considerably smaller again, so that installation is no longer a problem even with minimum installation depths. This additional design is available for switching currents from 100 mA to 3 A for SPDT as well as DPDT circuits.
Unrivalled Haptics
Increasingly high demands are being placed on design. Intuitive operation plays a major role to ensure the safety of the operating process through clear feedback. Thanks to their unrivalled haptic feedback, MSM switches are very popular, especially in combination with optical feedback (ring, point, area
lighting).
