Proximity inductive sensor ISM1-30.11.K

6...400rpm, Sn=9.5mm, 3-wire, PNP/NO, 10-30VDC, 250mA, M30x61mm

Price 44.1 EUR no VAT

The shielded inductive proximity sensor for direct current ISM1-30.11.K is used for speed control in the range from 6 to 400 rpm. The sensor has a metal cylindrical housing M30x61mm, with output type PNP with one normally open contact. The maximum distance of operation of the proximity sensor is 9,5mm. The sensor ends with a 3-wire PVC connecting cable with a length of 2m. The sensor has two LEDs, one showing the output state of the inductive sensor, and the other showing the length of the received impulses. The sensor's output is protected of overload and short circuit.


The presented inductive sensor M30 serve to monitor the minimum turnovers of conveyor belts, elevators, lifts, shafts and other rotating parts. It is used in direct current electrical circuits.
After applying the supply voltage the output of the sensor remain included for 7 seconds - the necessary time for acceleration of the slow-moving mechanisms. If turnovers of the rotating mechanism exceed the given ones, the output of the sensor remain on. But if turnovers the rotating mechanism are lesser than the given, the output of the sensor turn off. The minimum turnovers are set by trimmer potentiometer located at the back of sensor. It has two LED's: a red one - indicating the output signal of the sensor and green one - indicating the length of the incoming pulses.

Note: Sensor marked at the end with the letter "Z": after turning off the output, restore its operation by turning off and on the supply voltage (option on request).

Short description

The presented M30 inductive proximity sensor is used for monitoring the minimum revolutions of the shafts and the minimum allowable speed of conveyer belts, elevators and other automated systems. The sensor monitors the speed of passage of metal objects in front of its active part. The proximity sensor for speed control is resistant to moisture and dust. It has a long service life thanks to the non-contact switching of the electrical circuit in which it is connected.
