Wenglor HK12PA Retro-reflective sensor with background suppression 120mm sensing range PNP

The retro-reflective sensor with background suppression, also known as diffuse sensor, reflective light scanner, or optical proximity switch, from Wenglor with type number HK12PA, is an optoelectronic sensor for precise object detection. It has dimensions of 7 x 2 x 3 cm and weighs 0.049 kg. Retro-reflective sensors with background suppression detect objects by reflecting emitted light while ignoring the background. This enables reliable detection regardless of the color or texture of the background. Typical applications include industrial automation, for example, for position monitoring of workpieces on conveyor belts or for level control in containers. These sensors are frequently used in mechanical engineering to define precise switching points and increase process reliability.
