• As metal around the sensor may affect the sensing
performance, pay attention to the following points.
Influence of surrounding metal
• The surrounding metal will affect the sensing
performance. Keep the minimum distance specified in the

Embedding of the sensor in metal
• Sensing range may decrease if the sensor is completely
embedded in metal. Especially for the non-threaded type
and the non-shielded type, keep the minimum distance
specified in the table below.

Mutual interference
• When two or more sensors are installed in parallel or face
to face, keep the minimum separation distance specified
below to avoid mutual interference.

Refer to General precautions.
Sensing range
• The sensing range is specified for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coefficient
specified below. Further, the sensing range also changes
if the sensing object is smaller than the standard sensing
object or if the sensing object is plated.

Others
• Do not use during the initial transient time (10 ms) after
the power supply is switched on.
• Make sure that stress by forcible bend or pulling is not
applied directly to the sensor cable joint.
• GX-3S□, GX-4S□ and GX-5M□ do not incorporate
a short-circuit protection circuit at the output. Do not
connect them directly to a power supply or a capacitive
load.
