What type of sensor is this component?

It is a miniature retroreflective photoelectric sensor designed for standard object-detection applications, including the detection of transparent containers and materials.

Can this sensor detect transparent objects?

Yes. The sensor offers selectable contrast levels for detecting clear and translucent objects, including water-filled PET bottles, clear glass bottles and coloured glass.

What is the maximum detection range?

The effective detection range is up to 3.5 metres in Teach-In mode and up to 5.7 metres in the normal switch position. The specified threshold detection range is 7.6 metres when used with the reference reflector.

What type of light source does the sensor use?

It uses a modulated visible red LED with a wavelength of 660 nm. A polarisation filter helps the sensor distinguish reflected light reliably.

How are the contrast detection levels configured?

A five-position Teach-In switch is used to select and configure the contrast level. The available preset levels are 10%, 18% and 40%, allowing the sensor to be adapted to different transparent, coloured and opaque materials.

What applications suit each contrast setting?

The 10% setting is intended for clear, water-filled PET bottles, the 18% setting suits clear glass bottles, and the 40% setting is suitable for coloured glass or opaque objects.

What supply voltage does the sensor require?

The sensor operates from a 10 to 30 V DC supply. Its no-load current consumption is below 20 mA at 24 V DC.

What output configuration is provided?

The unit has two complementary push-pull outputs with light-on switching. The outputs are protected against short circuits and reverse polarity.

What are the output current and switching speed?

The maximum switching current is 100 mA, with a maximum switching voltage of 30 V DC. The sensor has a switching frequency of 1 kHz and a response time of 500 microseconds.

What do the indicator LEDs show?

The green LED indicates operating status, undervoltage and short-circuit conditions. The yellow LED indicates the switching state, signal stability and Teach-In status.

How does the sensor indicate whether Teach-In was successful?

Slow alternating flashing of the green and yellow LEDs indicates a successful Teach-In process. Rapid alternating flashing indicates that the process was unsuccessful, commonly because the received signal was insufficient or alignment with the reflector was incorrect.

What connection is fitted to the sensor?

Pepperl + Fuchs 218095 has a 3-metre fixed cable with an M16 cable gland and a six-pin AMP 926476-3 connector.

What are the sensor's physical dimensions?

The housing measures approximately 11 mm wide, 31 mm high and 23 mm deep. The unit weighs approximately 50 g, making it suitable for installations with limited space.

What environmental protection ratings does it have?

The housing is rated to IP67 and IP69K, providing strong protection against dust, water ingress and high-pressure washdown environments.

What temperature range can the sensor operate within?

The specified ambient operating range is -20°C to 60°C. The storage temperature range is -40°C to 75°C.

What materials are used in its construction?

The housing is made from glass-fibre-reinforced polycarbonate, while the optical face is manufactured from PMMA.

Which reflector is used as the reference target?

The specified reference target is the H85-2 reflector. Actual sensing distance and signal stability can vary with reflector type, alignment and the optical characteristics of the target.

Is a mounting accessory specified for this sensor?

Yes. The OMH-ML7-01 mounting aid is specified for ML7 and ML8 series sensors and can be used to position the sensor securely.

Which product standard does the sensor conform to?

The sensor conforms to EN 60947-5-2, the standard covering control-circuit devices and proximity switching equipment.
