Why Choose the IMO RX8/0T-3B Photo-Electric Switch?

The IMO RX8/0T-3B is a high-performance maxi diffuse-reflection photoelectric sensor designed for reliable non-contact object detection in industrial automation and machine control systems. Part of the established RX Series, this model combines a long 2 m nominal sensing distance with a multi-voltage AC/DC supply, relay output and integrated timer functionality.

Using the diffuse-reflection sensing principle, the RX8/0T-3B transmits infrared light towards the target and detects the reflected signal without requiring a separate reflector or receiver. A sensitivity adjustment trimmer allows the sensor to be configured for the application, while red output and green stability LED indicators provide clear visual feedback during installation and operation.

The RX8/0T-3B operates from 20–253 V AC or 20–60 V DC and provides a 3 A SPST relay output with NO/NC operation. Its integrated timer provides delay-on, delay-off and one-shot timing functions, while the standard M12 plug, fixing slide and robust IP65 housing make it a versatile choice for industrial machinery and automation installations.

Key Advantages

  • Long-range diffuse-reflection photoelectric sensing up to 2 m.
  • Wide 20–253 V AC / 20–60 V DC operating range supports varied control systems.
  • SPST relay NO/NC output allows direct switching of suitable industrial loads.
  • Integrated timer function provides delay-on, delay-off and one-shot operation.
  • Adjustable sensitivity enables accurate setup for different target conditions.
  • M12 plug connection supports straightforward installation and replacement.
  • Fixing slide provides flexible mechanical installation and sensor positioning.

Reliable Timed Object Detection for Industrial Automation

Diffuse-reflection photoelectric sensors such as the IMO RX8/0T-3B transmit light towards a target and monitor the light reflected back to the receiver within the same housing. This single-sided sensing arrangement simplifies installation because no separate reflector or receiving sensor is required, making it particularly useful for conveyors, production machinery and applications where access to the opposite side of the target is restricted.

The RX8/0T-3B adds flexible timer functionality to the sensing process, allowing delay-on, delay-off and one-shot switching behaviour to be configured for machine sequences. Combined with its wide AC/DC operating range and relay output, this allows the sensor to interface with a broad range of industrial control equipment, relays, contactors and PLC-based automation systems.

Typical Applications

  • Conveyor product detection and counting.
  • Packaging and production machinery.
  • Material handling and transfer systems.
  • Timed presence and position detection.
  • Automated assembly equipment.
  • Industrial door and access machinery.
  • Process sequencing and machine control.
  • OEM machinery and industrial automation systems.
