RS PRO PTE Series Photoelectric Sensors

The PTE series photoelectric sensors from RS PRO are economical and reliable compact devices typically found in parking system, architectural environments, manufacturing and logistics. The PTE range offers a series of detection types that include diffuse reflection, polarized retro-reflection and through beam reflection with various detection ranges.

How do they work?

A photoelectric sensor is a non-contact device which detects the presence or absence of an object regardless of material. The sensors do this by emitting a beam of infrared or red light at a photoelectric receiver to assess surroundings, detect objects or recognise the absence of an object.

Detection Types

Diffuse Reflection;• Diffuse reflection working principle;• Excellent anti-interference performance;• High detection accuracy;• IP67, suitable for harsh environments

Polarized Retro Reflection;• Polarized retro reflection working principle;• Suitable for detecting transparent or high reflective target;• High detection accuracy

Through Beam Reflection;• Through beam reflection working principle;• Excellent anti-interference performance;• High detection accuracy;Note: Emitter and receiver should be used in pairs

Features and Benefits

• Excellent anti-interference performance;• High detection accuracy;• IP67, suitable for harsh environments;• Output Types: NPN+PNP NO/NC or Relay;• Electrical Connection: 2 m PVC cable or M12 Connector
