The maximum operation distance stands for the maximum distance for which the sensor can detect the standard sensing object.The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient temperature drift and / or supply voltage fluctuation.It is the leakage current when the output is in the OFF state.The maximum load current varies with the ambient temperature. Refer to ' I/O CIRCUIT DIAGRAM' for details.When the cable is extended, the residual voltage becomes larger according to the resistance of the cable.

WARNING

CAUTIONS2●

●●●

●

●

This product has been developed / produced for industrial use only.Make sure that the power supply is off while wiring.Take care that wrong wiring will damage the sensor.Verify that the supply voltage variation is within the rating.If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicini-ty of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.Do not run the wires together with high-voltage lines or power lines or put them in the same race-way. This can cause malfunction due to induction.

Extension up to total 50m is possible with a 0.3mm2, or more, cable.Do not use during the initial transient time (50ms) after the power supply is switched on.Take care that the product does not come in con-tact with oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.Make sure that stress by forcible bend or pulling is not applied to the sensor cable joint.Since the cable end is not waterproof, do not use the sensor in the application where water may seep in from the cable end.Make sure that the sensing end is not covered with metal dust, scrap or spatter. It will result in malfunction.Never disassemble or modify this sensor. It will get damaged.

MOUNTING4●・

MountingBe sure to mount using an M3 (length 12mm or more) truss head screw. The tightening torque should be 0.5N・m or less.(Do not use a flat head screw or a pan head screw.)

Mutual interference preventionWhen two or more sensors are installed in parallel or face to face, keep the minimum separation dis-tance specified below to avoid mutual interference.

●・

Sensing rangeThe sensing range is specified for the stand-ard sensing object. With a non-ferrous metal, the sensing range is ob-tained by multiplying with the correction coefficient specified on the right.

Note: The sensing range will also change if the sensing object is smaller than the standard sensing object or if it is plated.

I/O CIRCUIT DIAGRAM3

Conditions for connected load(1) The load should not be actuated by the leakage current (0.8mA) in the OFF state.(2) The load should be actuated by (supply voltage -3V) in the ON state.(3) The current in the ON state should be between 3 to 70mA DC.

In case the current is less than 3mA, connect a bleeder resistance in parallel to the load so that a current of 3mA, or more, flows.
