Limit Switch with integrated LED Status Indication

Microprecision Electronics SA, a Swiss manufacturer of high precision snap action switches, limit switches and mechanical position sensors for industrial applications, now introduced its MP100/200 series microswitches with an optional integrated LED indicator light.

These microswitches with integrated LED status indicator have been designed for use at 24V in industrial automation applications. They allow a simple, visual control of the switching function, which can be very cumbersome to perform, in particular when the switch is mounted far away from the connected controller. Also, a broken cable will be instantly recognisable. In addition, the LED facilitates the intuitive calibration and adjustment during installation of the switching point in the field. For simple connection to a sensor box the switch will typically be provided with a 4-pin M12 cable connector interface. But other interface options like built-in M8 connector or a simple PVC cable are also available.

The LED can either be wired to indicate the NC or the NO operation. A bicolour LED can even indicate a changeover operation. The electrical interface is either made up as a PNP or NPN circuit.

The entire range of modular actuators for the MP100/200 series is compatible with the new LED indicator option. These actuators include telescopic actuators of different lengths, with and without rollers, different lever types with direct and/or indirect action, tilting rollers, wire levers and floater levers are also available.

The standard MP200 series switches are sealed up to IP68, this qualifies them for outdoor applications, for use under spray water and in full immersion (up to 20 meters depth). They also offer the possibility of switching two fully separate circuits (dual break). They are certified according to UL/EN standards for up to 15 A and suitable for temperatures up to 130°C (266°F). Microprecision also develops and implements custom solutions already for small production volumes.
