Why Choose the IMO QDRER/0P-0A Photo-Electric Switch?
The IMO QDRER/0P-0A is a compact through-beam photoelectric sensor transmitter and receiver set designed for reliable long-range object detection in industrial automation and machine control applications. Part of the IMO QD Series miniature photoelectric sensor range, the set uses separate transmitting and receiving units to provide dependable detection across conveyors, production machinery and material handling systems.
The QDRER/0P-0A provides a nominal working distance of up to 20 m and uses a visible 630 nm red light source. Its through-beam operating principle provides reliable detection because an object is sensed when it interrupts the light path between the transmitter and receiver. Adjustable sensitivity and selectable light-on or dark-on operation allow the sensor pair to be configured for different industrial detection requirements.
Designed for 10–30 V DC industrial control systems, the receiver provides a PNP NO/NC output with a maximum load current of 100 mA. Both units use integral 2 m cables, while the compact PA66 housings and IP67 protection rating support reliable installation in demanding industrial environments.

Reliable Through-Beam Detection for Industrial Automation
Through-beam photoelectric sensors use separate transmitter and receiver units positioned opposite one another. The transmitter projects a light beam towards the receiver, and an object is detected when it interrupts this beam. This operating principle provides excellent detection reliability and allows substantially longer sensing distances than many diffuse-reflective sensor arrangements.
The IMO QD Series combines compact construction with fast switching, adjustable sensitivity and industrial electrical protection. The QDRER/0P-0A is particularly suited to PLC-controlled machinery where dependable detection of products, components or moving materials is required over short or long spans.
Typical Applications
- Conveyor product detection and counting.
- Packaging and production machinery.
- Material handling and transfer systems.
- Automated assembly equipment.
- Presence and position detection.
- Machine entry and exit monitoring.
- OEM machinery and industrial automation systems.
