NJK Series Hall Type Proximity Sensor

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). For more information about the proximity sensors, please visit "What is Proximity Sensors".

● Please read "Precautions for Proximity Sensors" before use


● Lagging Distance: Less than 10% of detection distance

● Sensing Object: Magnetic metal (if non-magnetic object, the detection distance will be reduced)

● Supply Voltage: DC type — 12-24VDC (6-36VDC) with voltage pulsation (p-p) below 10%; AC type — 110-220VAC (36-250VAC), 50/60Hz

● Current Consumption Type N.P — under 13mA; Type D — under 0.8mA; Type A — under 1.7mA

● Control Output: Type N.P — under 300mA; Type D — under 200mA; Type A — under 400mA

● Circuit Protection: Type N.P.D — Reverse power supply protection, surge absorption, short-circuit protection; Type A — Surge absorption

● Ambient Temperature (operating, storage): -30-+65°C (non-freezing, non-condensing)

● Ambient Humidity (operating, storage): 35-95%RH

● Withstanding Voltage (1min): 1000VAC, 50/60Hz (between charging section and case)

● Temperature Effect: If the temperature range is -30 to +65℃, the sensing distance is within ±15% of the detection distance at +23℃; if the temperature range is -25 to +60℃, the sensing distance is within ±10% of the detection distance at +23℃.

● Voltage Effect: If the voltage range is within ±15% of the rated supply voltage, the sensing distance is within ±10% of the detection distance at the rated supply voltage.

● Protective Structure: IP67 (IEC standard)

● Material: Housing — chrome plated brass; Detection surface — ABS
