The Pepperl+Fuchs 087797 (OBT500-18GM60-E5-V1) is a diffuse-mode photoelectric sensor designed to detect objects without a separate reflector. It uses infrared light and has an adjustable sensing range of up to 500 mm, measured against a standard white target.
Its nickel-plated brass M18 cylindrical housing is rated IP67 and connects through a 4-pin M12 connector. The sensor operates on 10–30 V DC and provides a PNP output with selectable light-on or dark-on switching. A dual-colour LED shows the switching state and sensing stability, while a 1 ms response time and 500 Hz switching frequency suit fast-moving industrial processes.

What type of sensor is this?
It is a diffuse-mode photoelectric sensor. It emits infrared light and detects objects from the light reflected back towards it, without needing a separate reflector.
What is its detection range?
The specified detection range is 0 to 500 mm, measured using a standard white reference target. The effective range can vary with an object’s colour and surface.
What power supply does it require?
It operates from a 10 to 30 V DC Class 2 power supply. Its no-load supply current is no more than 25 mA.
What kind of output does it provide?
It has one PNP, open-collector output rated for a maximum switching current of 100 mA and a maximum switching voltage of 30 V DC.
Can it be set to detect an object arriving or leaving?
Yes. Light-on and dark-on switching are electrically selectable, allowing the output behaviour to suit the intended detection sequence.
How quickly does it respond?
The specified response time is 1 ms, and the switching frequency is 500 Hz.
What connection and housing does it use?
It has a four-pin M12 × 1 connector and a cylindrical M18 × 1 nickel-plated brass housing.
Can the sensing distance be adjusted?
Yes. A sensing-range adjuster lets you set the sensor for the target and installation.
What do the indicator lights show?
A green indication shows that power is on, while yellow indicates the switching state. A flashing indication signals an unstable sensing range.
What environmental conditions is it rated for?
The sensor has an IP67 protection rating and a specified ambient operating temperature range of −25 °C to +55 °C.
What should be considered when detecting dark objects?
Dark surfaces generally reflect less light than the standard white reference target used for the range specification. Check detection at the intended distance with the actual object and adjust the sensing range accordingly.
- Detecting objects as they pass a fixed point on a conveyor.
- Counting items moving through a packaging or production line.
- Confirming that a product is present before an automated process begins.
- Checking whether components have reached a designated position in an assembly machine.
- Detecting boxes, cartons or other items during sorting and handling.
- Monitoring the presence of parts in feed and transfer mechanisms.
