٨࡮Influence of surrounding metal

When there is a metal near the sensor, keep the minimum separation distance specified below.

ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.

The output does not incorporate a short-circuit protection circuit. Do not connect it directly to a power supply or a capacitive load.

Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

Do not use during the initial transient time (10ms) after the power supply is switched on.

Extension up to total 100m is possible with a 0.3mm

SENSING RANGE

Please use it by 1.8mm or less. However, this value is a value over a standard detection object (iron 1515t1mm). With a non-ferrous metal, the sensing range is obtained by multiplying with the correction coefficient specified on the right.

Keep in mind that detection dis-

Further, the sensing range also changes if the sensing object is plated.
