Description

The E3F-DS30Y1 / RF18-30A1 is a through-beam or retro-reflective photoelectric sensor utilizing an infrared LED and phototransistor pair to detect the presence or absence of objects. Its normally open (NO) solid-state output switches upon detection, capable of directly driving relays, contactors, or PLC inputs within its 400mA current rating.

Engineered for harsh industrial environments, the sensor housing protects internal components from dust and incidental moisture. The wide AC voltage input allows it to be powered directly from common industrial control circuits without additional power conditioning. The sensing distance is field-adjustable, enabling fine-tuning for specific object sizes and background conditions.

Key Features

  • High-current NO output (400mA) for direct load switching.
  • Broad AC input voltage (90-250V AC) ensures compatibility with global industrial power standards.
  • Field-adjustable sensing range (5-30 cm) provides application flexibility.
  • Durable housing designed for reliable performance in temperatures from -30°C to +75°C.
  • Integrated 1.2-meter cable simplifies wiring and reduces installation time.
  • Consistent detection performance for objects of varying reflectivity.
  • Ideal for high-speed counting, positioning, and presence verification tasks.

Applications

  • Object detection on conveyor belts and automated assembly lines.
  • Package counting and sorting in material handling and packaging systems.
  • Position verification and end-of-travel sensing in machinery.
  • Bin level detection for bulk material handling.
  • Safety interlock and door/gate monitoring in industrial equipment.

Frequently Asked Questions

What is the output type of the E3F-DS30Y1 sensor?

The sensor features a Normally Open (NO) solid-state output. When an object is detected within its sensing range, the output switch closes, allowing current to flow to the connected load, up to its maximum rating of 400mA.

Can this sensor be used with DC power supplies?

No, this sensor is designed specifically for AC operation within the range of 90 to 250 volts AC. Applying DC voltage will not power the sensor correctly and may cause damage to its internal circuitry.

How do I adjust the sensing distance?

The sensing distance, typically between 5 and 30 cm, is adjustable via a potentiometer or sensitivity screw located on the sensor body. Refer to the unit's markings and adjust while testing with your target object to achieve reliable triggering.

What is the maximum load the output can handle?

The NO output can switch a load of up to 400mA. This is sufficient to directly control small relays, solenoids, or PLC digital inputs without requiring an intermediate amplifier in most industrial control scenarios.
