Conforming to
EMC Directive
Exclusive mounting bracket is needless
Low price
Wide variation
The GL-N12 series can be reliably
fixed even without an exclusive
mounting bracket as a boss is
provided on the bottom face of the
sensor to prevent rotation.
The GL-N12 series is recommended to
large volume users for cost reduction.
A wide variety of 16 types, front
sensing type / top sensing type,
normally open type / normally closed
type, as well as, different frequency
type, PNP output type, etc., is
available.
You can choose from the vastly
increased variety to suit your
application.

Long sensing range
Waterproof
It achieves a sensing range of 4 mm
0.157 in with a 12 mm 0.472 in squaresize sensing part.
It can reliably detect an object even if
its position varies slightly.
Since the sensor has IP67 protection,
it can withstand water splashes.
