Photoelectric switch is the use of the test object to blocked or reflected beam, by the synchronization loop gating circuit to detect the presence or absence of the object. All objects can reflect light can be detected. E3JK-R4M1 AC90-250V square lens reflex photoelectric switch five lines.

Advantages:

Small size, multi-function, long life, high precision, fast response.

Detection distance and anti-light, electricity, magnetic interference capability advantages.
