WL12G-V530

What type of sensor is this?

This unit is a photoelectric retro-reflective sensor designed for object detection using a separate reflector. It emits visible red LED light and detects interruption of the returned beam.

How does a retro-reflective sensor work?

A retro-reflective sensor is mounted opposite a reflector. The sensor sends light towards the reflector and monitors the returned signal. When an object passes between them and interrupts the beam, the sensor changes its output state.

What sensing distance can be expected?

With the recommended PL80A reflector, the operating range is up to 2.7 m, with a maximum sensing range of 3 m. Shorter ranges apply when smaller reflectors are used.

Which reflector is normally used with this sensor?

The standard pairing is the PL80A reflector. In the WL12G-V530 range data, this reflector provides the longest operating distance, while smaller reflector options reduce the usable range.

What output type does the sensor provide?

It has a PNP switching output with light-on operation. In practical terms, the output changes when the reflected light is received in the defined switching condition.

What supply voltage does it require?

The sensor operates on 10 V DC to 30 V DC, making it suitable for a wide range of common industrial control voltages.

How is the sensor connected?

It uses a 5-pin M12 male connector. The pinout includes supply, output, an additional QP connection, and a teach input.

Can the sensing setting be adjusted?

Yes. The unit includes a potentiometer for adjustment, allowing the switching behaviour to be tuned for the application.

What light source does it use?

It uses a visible red LED light source. This can be helpful during alignment because the beam direction is easier to identify during installation.

Is it suitable for demanding industrial environments?

The sensor has an IP67 enclosure rating and a metal zinc die-cast housing with PMMA optics. This makes it well suited to industrial machinery and automated equipment where a compact but robust sensor is needed.

What are the physical dimensions?

The housing measures 15 mm wide, 49 mm high and 41.5 mm deep. Its compact rectangular form helps when fitting the sensor into tighter mounting positions.

What mounting features are included?

The housing includes an M4 threaded mounting hole with 4 mm depth and a 4.2 mm mounting hole. These options give flexibility when positioning the sensor during installation.

How fast is the response time?

The response time is 0.5 ms or less, which makes it suitable for fast detection tasks on moving equipment and conveyor-based processes.

What temperatures can it operate in?

The ambient operating temperature range is -25 °C to +60 °C. For storage, the temperature range is -40 °C to +75 °C.

What is the current consumption?

Current consumption is 65 mA without load. This is useful when sizing the available power budget in the control circuit.
