A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam through a polarization filter toward a distant reflector. Reflected light returns to the sensor, passing through a second filter before arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor.

Photoelectric Analog output

Photoelectric sensors with analog outputs are ideal for measuring values of distance. Using triangulation technology, analog photoelectric sensors produce an output signal that is accurately calibrated and approximately proportional to the distance of the target from the...

Photoelectric Color

Color photoelectric sensors utilize energetic-diffuse sensing technology to detect variations in target color, allowing color sorting or color control that is independent of target speed or distance. Using a “teach-in�? function to program up to three separate...

Photoelectric Diffuse

A diffuse-mode, or energetic-diffuse, photoelectric sensor is a reflective sensor, containing a transmitter and a receiver in a single housing. The sensor emits a light beam toward a distant target that acts as a reflector, returning part...

Photoelectric Fiber Amplifier

Fiber-optic sensors are common in explosive environments or in the presence of strong electromagnetic fields – in these areas, sensors that rely on electrical signals may present a risk of explosion or fail to operate correctly. Contrinex...

Photoelectric Reflex

The relatively high level of reflected light allows reflex sensors to achieve sensing distances up to six meters, and the polarization filters prevent light reflected by other objects from reaching the receiver, ensuring reliable detection, even with...

Photoelectric sensors with background suppression

Diffuse-mode photoelectric sensors with background suppression emit a focused light beam toward a distant target. Part of the beam is reflected from the target and returns to the sensor, striking a position-sensitive receiver. The receiver distinguishes between...

Photoelectric Through Beam

A through-beam photoelectric sensor comprises a transmitter and receiver, each mounted in a separate housing. The transmitter emits an aligned, pulsed beam of light toward the receiver, which is mounted beyond the target area. The target interrupts...
