Honeywell now offers a pressure switch portfolio consisting of high, medium and low pressure options. The new ME Series medium pressure switches provide a set point range of 25 to 350 psi. The HP Series now include seven new port connector options, and a minimum set point of 100 psi compared to 150 psi previously.

Honeywell Pressure Switches
• High Pressure:  HP Series, HE Series
• Medium Pressure:  ME Series
• Low Pressure:  LP Series, LE Series

Honeywell’s pressure switches are durable, reliable electromechanical gauge pressure on/off switches. Their high proof and burst pressure ratings allow for use in many rugged applications that require the making or breaking of an electrical connection in response to a pressure change of the system media.

Due to the demanding conditions found within industrial and transportation industries, pressure switches are often designed into equipment and vehicle applications to make or break an electrical connection in response to a system pressure change. These switches are frequently exposed to chemical splashes, dirt, grime, and harsh media, as well as performance spikes. They must provide reliable and consistent performance and have a high life cycle rating.

Metal Line Switches with Multicolor Illumination

and Variable Input Voltage

Schurter is expanding its PSE, piezo metal switch and MCS 30, mechanical metal switch series, with new illumination possibilities powered by variable input voltages. Based on the used RGB color technology, it’s now possible to indicate up to seven illumination color options with just one switch. The variable power supply offers a homogenous and brilliant illumination within a voltage range of 5 to 28 VDC.

The new multicolor illumination of the PSE and MCS 30 series is made easy using convenient color-coded wires in each of the illumination colors. Each color is given a specific voltage between 5 to 28 VDC. The constant brightness intensity is maintained regardless of applied voltage. The standard version is offered in red, green, and blue. Additional color options include yellow, cyan, magenta and white, which can be made through additive color mixing. As soon as the 2 or 3 wires are supplied with the applied voltage at the same time, the result is a mixed color. The traffic light colors of red, green and yellow (RGY) for status indication are also available as a standard version. No additive color mixing is required to produce the color yellow.

The new RGB multicolor illumination option greatly expands the application range of the PSE and MCS 30 button style switches. The PSE is available in 22 / 24 / 27 / 30 mm diameters; the MCS 30 is available with a 30 mm diameter. The PSE has an IP69K ingress protection rating. It has no moving actuator and is thus absolutely impervious to any leaks or accumulation of dirt underneath or around the switch surface. This technology is ideal for hygiene-related applications such as medical equipment, food processing equipment and outdoor applications subject to vandalism such as ticketing machines.

The MCS 30 is an alternative to the highly robust, solid state PSE. It is also designed for demanding applications, although it uses a tactile switch that provides a clear haptic feedback. It has a lifetime rating of one million actuations, as opposed to the PSE's 20 million operations. The switch contacts are sealed from the front and rated IP65.

Technical Data:
- Variable input voltage from 5 – 28 VDC
- Multicolor Illumination with 7 different colors
- Red, green, yellow configuration for status indication
- Customer specific adjustments are possible
- IP69K for the piezo switches
- Easy to clean

Applications:
- Medical equipment
- Public applications
- Industrial applications
- Household appliances
- Design sensitive applications

Schurter expands its wide range of current compensated chokes with high current types for PCB mounting. The new DKIH series are available for single and three phase applications with rated currents from 10 to 50 amperes. Due to its open design, the chokes are light weight and compact, ideally designed to suppress EMI noise caused by power applications on the PCB.

Like all other aspects of electronic design, the power portion is oftentimes built today using discrete components on printed circuit boards. With the trending integration of components, to achieve smaller and smaller form factors, thermal problems and high currents on the PCB can arise. It also becomes increasingly challenging to meet EMC requirements with a filter package due to the resulting space constraints; therefore a filter on PCB with discrete components is a good solution. Next, the capacitors and a common mode choke, with asymmetrical effective inductance, are very effective to dampen EMI noise.

The new DKIH-1 series is suitable for single phase AC or DC applications from 10 up to 50 amperes. Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). They are designed and approved according IEC 60938, UL 1283 and CSA 22.2 no. 8. The voltage rating is 300 VAC (IEC, UL) and 250 VAC (CSA).

The new DKIH-3 series is suitable for three phase AC applications from 10 up to 50 amperes. The common mode chokes are also designed according IEC 60938 and are rated 600 VAC, making them suitable for many applications.

The DKIH-1 and -3 have a wide temperature range of -40 to +100°C. They are available with a standard pin out or customer specific pin out. Variations in the winding are also available on request.

Technial Data DKIH-1:
- Rated voltage: 300 VAC (UL, ENEC), 250 VAC (CSA), 425 VDC
- Rated currents: 10 to 50 A (ENEC / UL / CSA) at 40°C
