MPM connectors are used for electrical connections in different applications; the most common is the connection with hydraulic and pneumatic electromagnetic devices, such as solenoid valves. They can also be used as a plug-socket on pressure switches, sensors of all types, low-power motors and motor-reducers and in many other industrial applications where a fast and safe connection is required. MPM offers a wide range of circuits applicable to connectors for solving any kind of electrical problem. There are circuits for signaling the presence of voltage (by means of a lamp or LED) and protection devices using variators, diodes and transil (with or without signaling). The range includes connectors with bridge rectifier circuit and two-color LED circuit.
