Sensors cope with railway demands
Railway applications involve extreme temperature conditions, dust and humidity influences as well as vibrations or shock impact.
Railway applications are a difficult environment for sensitive electronic sensors If users want to detect the open/closing of doors or the proper engagement and locking of the mechanical coupler between units of a train set they are forced to find a solution which has to work under extreme temperature conditions, dust and humidity influences as well as vibrations or shock impact

Electronic sensing solutions have limited temperature range and sensitivity to electromagnetic fields, and are generally not reliable enough.
A sealed mechanical switch is a better solution for a position detection system.
Microprecision Electronics offers the MP210 IP67 switch mechanism with an extended mechanical life The mechanical actuator can be modified for specific needs, such as in a door locking application where the lever had to be extended and bent in order to fit into the already built door frame.
The coupler between train units is typically exposed to shock, dust and humidity.
The MP210 sealed switch detects the proper locking of the coupler.
The temperature range of - 40 to +130C allows its use in all regions of the world and the IP67 protection keeps all dust or water off the switching circuit.
Other applications where IP67 and temperature resistance are required include brake detection, pneumatic door lock detection or sensing of the take up position.
