Proximity inductive sensor ISP1-18.71.U1
6...400rpm, Sn=8.0mm, 2-wire, NO, 90-240VAC, 10-300mA, M18х59mm
The unshielded inductive proximity sensor for alternating current ISP1-18.71.U1 is used for speed control in the range from 6 to 400 rpm. The sensor has a plastic cylindrical housing M18x59mm, with normally open contact. The maximum distance of operation of the proximity sensor is 8,0mm. The sensor ends with a 2-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 has no protection of short circuit. AC sensor designated with the symbol (U2) have an operating voltage 40-100VAC, with symbol (U3) it is 20-50VAC (by request). Example: ISP1-18.71.U2 or ISP1-18.71.U3
The presented inductive sensor M18 serve to monitor the minimum turnovers of conveyor belts, elevators, lifts, shafts and other rotating parts. It is used in alternating 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).

Overall dimensions (mm)
The presented M18 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.
