EP Series Square Photoelectric Sensor

EP series photoelectric sensor, with CE certification, standard common size, can replace the international brand in nice price; Adopting imported microchip, quick response time.
Product Details

Standard size:

Universal standard size, which replace many China and    international brands;

Built-in M3 metal thread to strengthen the sensor;

Imported chip design is adopted, faster response speed;


Optimized interference avoidance algorithm, stronger ability in anti-light and electromagnetic interference;

Adopting anti-interference design, up to two sensors can be installed to each other;

Equipped with output reverse connection protection to avoid sensor wiring failure.

Sensitivity can be adjusted:

Three-wire type, adjustable sensitivity, NO/NC switchable;

The optical axis adjustment is simple, and the deviation between the optical axis and the mechanical axis is controlled within ±2.5°.


EP-T6N is not easily affected by opening and 
hollowing of the substrate, which can stably detect
 the position of the substrate

EP-D06N one side and long distance to d
etecting if object pass

EP-DL03N small light spot design, easy to 
detect whether small workpieces pass

EP-R3N Conveyor belt baggage passing detection

EP-DLS03N Confirmation of passing workpiece.
The BGS function is not affected by the color of 
object and background

EP-R3N Polarization filter, stable detecting the 
bright and transparent objects.

EP-T6N The logistic device  can carry out remote 
distribution and departure inspection of the goods

EP-T6N Inspection of the inlet and 
outlet of the injection molding machine

EP-T6N Automatic warehouse, cargo 
storage and drop detection
