Contrinex Sensors
Photoelectric Sensors
A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam toward a distant reflector.
Reflected light returns to the sensor, arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor. The relatively high level of reflected light allows reflex sensors to achieve sensing distances up to eight meters. For applications where the target object itself reflects light back toward the sensor, models with polarization filters are available.The filters ensure that only light returned from the reflector reaches the receiver, ensuring reliable detection, even with reflective targets.

Photoelectric Diffuse
A diffuse-mode, or energetic-diffuse, photoelectric sensor is a reflective sensor, containing a transmitter and a receiver in a single housing.
Photoelectric Background suppression
Diffuse-mode photoelectric sensors with background suppression emit a focused light beam toward a distant target.
Photoelectric Reflex
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.
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.
Photoelectric Through Beam
A through-beam photoelectric sensor comprises a transmitter and receiver, each mounted in a separate housing.
Photoelectric Color
Color photoelectric sensors utilize energetic-diffuse sensing technology to detect variations in target color, allowing color sorting or color control.
Photoelectric Optical amplifier
Fiber-optic sensors are common in explosive environments or in the presence of strong electromagnetic fields.
