What type of sensor is this component?

It is a cylindrical photoelectric retro-reflective sensor from the GR18 family. It detects objects when they interrupt the visible red light travelling between the sensor and a reflector.

What is the sensing range?

The specified operating range is 0.06 m to 6 m when used with a PL80A reflector. The maximum sensing range is 0.03 m to 7.2 m, although the achievable distance depends on the reflector and installation conditions.

Does the sensor require a reflector?

Yes. As a retro-reflective sensor, it requires a compatible reflector positioned opposite the sensor. Options include the PL80A, PL40A, PL20A, P250 and PL22 reflectors.

What supply voltage does it require?

The sensor operates from a 10 V DC to 30 V DC supply and has a typical current consumption of 30 mA.

What type of switching output does it have?

It has a PNP transistor output with dark-switching operation. The output changes state when an object blocks the light path between the sensor and reflector.

What is the maximum output current?

The maximum output current is 100 mA. If the supply exceeds 24 V or the ambient temperature exceeds 49 °C, the maximum output current is reduced to 50 mA.

How quickly can it detect an object?

The response time is less than 500 microseconds, and the switching frequency is up to 1,000 Hz with a 1:1 light-to-dark ratio.

How is the sensor electrically connected?

It uses a three-pin M12 connector. Pin 1 is the positive supply connection, pin 3 is the negative supply connection and pin 4 carries the PNP switching output.

What are the sensor's dimensions and mounting arrangement?

The body measures 18 mm × 18 mm × 38.1 mm and has a cylindrical M18 × 1 threaded housing. Two metal fastening nuts are included for mounting.

What do the indicator LEDs show?

The green LED indicates that power is on. The yellow LED remains illuminated when no object is present and switches off when an object is detected.

Is the sensor suitable for demanding industrial environments?

Part 1058198 has an IP67 enclosure rating and a housing made from nickel-plated brass and ABS. Its optical surface is made from PMMA plastic.

What ambient temperatures can it operate in?

The specified operating temperature range is −25 °C to +55 °C, subject to the stated voltage and output-current conditions. The storage temperature range is −40 °C to +70 °C.

What type of light source does it use?

It uses a visible red PinPoint LED with a wavelength of 650 nm. The light spot diameter is approximately 175 mm at a distance of 7 m.

Does it include a polarization filter?

Yes. The integrated polarization filter helps the sensor distinguish reflected light from unwanted reflections, improving object detection in suitable applications.

Which mounting accessories are suitable?

The BEF-WN-M18 mounting bracket is designed for M18 sensors. A BEF-WN-REFX universal bracket can be used to position compatible reflectors, while the P250 is a rectangular screw-mounted reflector option.
