B. Working Principle
The Omron E3FA-DP13 2M works using the diffuse reflective photoelectric sensing principle.
The sensor emits red light toward the target object. When an object enters the detection area, part of the emitted light is reflected from the object's surface back toward the receiver inside the sensor.
The internal electronics monitor the returned light level. When the reflected light reaches the switching threshold, the sensor changes its PNP output state.
This design does not normally require a separate reflector or separate receiver because the transmitter and receiver are integrated into the same sensor housing.
For the E3FA-DP13 2M, Omron specifies a 624 nm red LED, a 1 m sensing distance with a 300 x 300 mm white paper target, and selectable Light ON or Dark ON operation.
C. Why Is the Omron E3FA-DP13 2M Used?
