FAQ

1. What is an M18 photoelectric sensor?
An M18 photoelectric sensor is a threaded cylindrical optical sensor used to detect objects, distance, or changes in surface using light, ideal for industrial automation and OEM applications.

2. What are the main types of M18 sensors available?
There are three main types: diffuse reflection (direct detection), retro-reflective (using a reflector), and through-beam (separate emitter and receiver for long range).

3. How far can the M18 photoelectric sensor detect?
Detection distance varies by type: up to 300 mm for diffuse, 3 m for retro-reflective, and 10 m for through-beam models.

4. Can the sensor work in dusty or humid environments?
Yes. With an IP65 or IP67 rating, it is protected from dust and water spray, suitable for most industrial environments.

5. What output types do you offer?
We provide both PNP and NPN outputs, with NO (normally open) or NC (normally closed) options for flexible integration.

6. Is customization available for OEM orders?
Yes. We offer OEM/ODM services, including branding, cabling, housing material, and detection range customization.

7. How should I wire the M18 sensor to a PLC system?
Connect power (DC10–30V), output, and ground according to wiring diagrams. For M12 connectors, plug-and-play options simplify setup.
