Magnetic sensor MP4-30.21.R

Sn=10mm, 3-wire, NPN/NO, 5÷35VDC, 200mA, 30x6.4x5mm

Price 14.04 EUR no VAT

Magnetic sensor MP4-30.21.R for direct current for pneumatic cylinders. The sensor is in a 30x6.4x5mm plastic housing and has one NPN normally open "reed-contact" output. The maximum distance of operation of the magnetic sensor is 10mm (depends on the intensity of the magnetic field). The sensor ends with a 3-wire PVC connecting cable with a length of 2m and has an LED indicator showing the output state of the magnetic sensor.


The magnetic proximity sensor series MP4-30 is made on the base of reed-contact and serves to commutate direct current electric circuits. It is specialized for groove montage on pneumatic aluminum cylinders. It can also be used on other facilities. The principle of operation is to bring a permanent magnet closer to its active part, whereby the electrical circuit in the sensor closes and current flows. If there is a magnet in front of the active part of the sensor, the output indicator is on.
