Technical Overview
The Pepperl+Fuchs OBD500-18GM60-E5-IR-1C is an infrared diffuse-mode photoelectric sensor with a 30–500 mm adjustable operating range and an M18 x 1 metal housing. It uses an IRED source and provides a configurable PNP switching output, supplied by 10–30 V DC, with a 500 Hz switching frequency and response time of 1 ms or less. A 2 m fixed cable, IP67 protection, and a -40 to 60 °C operating range suit industrial sensing installations; the manufacturer product listing shows the model as in stock.
M18 infrared diffuse sensor with an adjustable 30–500 mm range, fast PNP switching, a 2 m cable, and IP67 protection.
Key Features

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Presence detection on a conveyor
A packaging or assembly conveyor may need to detect cartons or other suitably reflective targets at a defined point without a separate reflector.
Potential use
The diffuse sensor can be adjusted for a 30–500 mm target distance, with a PNP output for a compatible controller input. Confirm the target's color, finish, size, and background conditions because diffuse sensing range depends on the target.

2. Object detection in a washdown-adjacent cell
An industrial cell may need a compact threaded sensor near routine moisture exposure while detecting items at a moderate standoff.
Potential use
The metal M18 body, IP67 protection, and adjustable infrared sensing range may suit this role when mounted and cabled according to the specified enclosure limits. Check the actual cleaning method, optical target properties, and connector/cable routing for the installation.
