Red Lion Controls MP37CA00 Datasheet & Stock

The MP37CA00 is a magnetic pickup sensor comprising a permanent magnet, pole-piece, and sensing coil encapsulated within a cylindrical housing. When a ferromagnetic target such as iron or steel passes close to its pole-piece, it distorts the magnetic flux, generating an electrical signal. The signal's amplitude depends on the target's size, approach speed, and proximity, while its polarity indicates whether the target is moving toward or away from the sensor. This device is commonly used for sensing gear teeth, sprockets, timing belt wheels, bolt heads, keyways, and other moving machine components. It features an in-line preamplifier, making it a simple, reliable, and economical solution for pulse generation, speed sensing, and frequency-to-DC conversion. The sensor is self-generating, requiring no external power, and is protected by epoxy encapsulation, making it resistant to dirt, oil, and water with no maintenance needed. It typically uses an M12 connector (model-specific) and finds applications in industrial sensing and instrumentation.
