Sensing range
• The sensing range is specied for the standard sensing
object. With a non-ferrous metal, the sensing range is
obtained by multiplying with the correction coefcient
specied 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.

Wiring
Others
• 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 use during the initial transient time (50 ms) after
the power supply is switched on.
Inuence of surrounding metal
• When there is a metal near the sensor, keep the minimum
separation distance specied below.

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

Notes: 1) “I” in the model No. species
the different frequency type.
2) Close mounting is possible for up to two sensors.
When mounting three sensors or more at an equal spacing, align
the model with “I” and the model without “I” alternately. The minimum
value of dimension “H” should be as given below.

PRECAUTIONS FOR PROPER USE
Refer to General precautions.
Notes: 1) When using MS-GX6-1 (recommended mounting bracket), the
distance “A” including the thickness of mounting bracket will be
6.4 mm 0.252 in.
2) The GXL-FL15 type should be mounted on an insulator. To mount
it on an iron or stainless steel, use the enclosed aluminum sheet.
Note: When GX-HL15 type is mounted on an insulator or seated on the
enclosed aluminum sheet, the distance “F” can be zero.
