About Photoelectric Sensor

A photoelectric sensor detects objects or changes in its environment using light beams, typically infrared or visible red light, making it essential for non-contact automation tasks. It consists of an emitter that transmits light and a receiver that senses variations when light is interrupted or reflected.

Key Components-

The emitter uses LEDs or lasers to generate a focused light beam, while the receiveroften a photodiode or phototransistorconverts received light changes into electrical signals. Amplifiers process these signals to trigger outputs like switches connected to PLCs or controllers.

Operating Types

Through-beam: Separate emitter and receiver aligned directly; offers longest range but needs precise alignment.
Retro-reflective: Emitter and receiver in one unit with a reflector; light bounces back unless blocked.
Diffuse (proximity): Light reflects off the target itself; simplest setup for short-range detection.

Main Applications

These sensors excel in industrial automation for object counting, position detection, conveyor monitoring, and level sensing. They handle materials like metal, plastic, or even transparent items in manufacturing, packaging, and HVAC systems.

Robust Object Detection for Automation

Engineered for high precision, this sensor excels in industrial automation where fast and accurate object detection is crucial. The retro-reflective sensing mode works with a reflector to detect even the smallest items, enhancing productivity on conveyor lines and packaging systems.

Durable Design for Industrial Conditions

With an IP67 ingress rating and robust ABS plastic housing, the sensor endures moisture, dust, and challenging temperatures ranging from -25C to +55C. Its pre-wired, threaded mount and versatile output options make installation and integration straightforward yet secure.

Flexible Connectivity and Precise Performance

The 3-wire pre-wired cable and M18 threaded mounting enable quick setup in different industrial scenarios. Adjustable sensitivity and immunity to ambient light (up to 10,000 Lux) ensure reliable operation, while a LED indicator simplifies real-time status monitoring.
