NJK Series
Hall Type Proximity Sensor
NJK series Hall type proximity sensor is a cylindrical shape proximity sensor with 10mm detection distance , and 0-8mm setting distance. NJK series proximity sensors have the advantages of adjustable distance, simple to operate, long life and high reliability, and can adapt to complex working environments. NJK series proximity sensors are equipped with power reverse protection, etc., and the operating status of the sensor can be directly observed through the red LED. NJK series proximity sensors are IP67 protected (IEC standard). Depending on the control output, proximity sensors can be divided into NPN type (Type N), PNP type (Type P), AC type (Type A), and DC type (Type D).
