Description

The Aotoro ER18A-D50C4 photoelectric sensor utilizes a modulated infrared LED light source and a receiver to detect objects via the diffuse reflective principle. The sensor’s output switches based on the intensity of light reflected back from a target, making it suitable for detecting objects without requiring a separate reflector. Its integrated circuit provides robust protection against short circuits, reverse polarity, and voltage surges.

Housed in a durable ABS plastic body, this sensor is designed for long-term reliability in industrial environments. It operates across a wide temperature range from -25°C to +60°C and 35-85% relative humidity, ensuring stable performance in challenging conditions. The compact 18mm diameter and 45mm length facilitate easy integration into machinery, conveyor systems, and automated equipment.

Key Features

  • Compact 18mm diameter ABS plastic housing for versatile mounting.
  • Diffuse reflective sensing type with a 50cm (0.5m) standard detection distance.
  • Wide 12-24VDC operating voltage range compatible with industrial PLCs and controllers.
  • User-selectable Light ON (NO) or Dark ON (NC) operation via wiring configuration.
  • Fast 1ms maximum response time enables high-speed counting and positioning.
  • IP64/IP67 environmental sealing protects against dust ingress and water jets.
  • Integrated protection against short-circuit, reverse polarity, and surge events.
  • Low 15mA current consumption for energy-efficient system design.

Applications

  • Object presence detection on conveyor belts and assembly lines.
  • Counting and sorting opaque, translucent, or transparent packages.
  • Machine guarding and safety interlock systems.
  • Level detection for bins, hoppers, and storage containers.
  • Position verification in automated packaging and material handling equipment.

Frequently Asked Questions

What is the operating voltage range for the ER18A-D50C4 sensor?

The sensor operates on a wide 12 to 24 VDC power supply, making it directly compatible with standard industrial 24V PLC systems and 12V automotive/control voltages. Ensure your power source is stable and within this range for reliable operation.

How do I select between Light ON and Dark ON output modes?

The Light ON (normally open) or Dark ON (normally closed) function is selected by wiring. Consult the sensor's datasheet for the specific connection diagram. Typically, you connect the load (e.g., PLC input) between the output wire and either the positive or negative supply line to choose the desired logic state.

What is the difference between diffuse reflective and through-beam sensing?

This ER18A-D50C4 model is a diffuse reflective type. It houses both the light emitter and receiver in one unit, detecting light reflected off the target object. Through-beam types use separate emitter and receiver units placed opposite each other, detecting an object that breaks the light beam, typically allowing for longer detection distances.

Can this sensor detect transparent objects like glass or plastic?

Yes, diffuse reflective photoelectric sensors like the ER18A-D50C4 can be effective for detecting transparent and translucent materials, although detection reliability depends on the material's reflectivity and thickness. Optimal sensing may require careful adjustment of the sensor's sensitivity and alignment relative to the target.
