Frequently Asked Questions
Q: What is a diffuse reflection photoelectric sensor and how does it work?
A: A diffuse reflection photoelectric sensor emits an infrared light beam and detects objects when that beam is reflected back by the object itself — no separate reflector or receiver is needed. The BR Series M18 sensor combines the emitter and receiver in a single M18 barrel housing, making installation simple and compact. When an object enters the 1–40 cm detection zone, the sensor triggers its output signal.
Q: What devices can I connect the CKCTINNER BR Series sensor to?
A: The BR Series photoelectric switch is compatible with most standard industrial control systems including PLCs (Programmable Logic Controllers), Arduino and Raspberry Pi microcontrollers, relay modules, and other automation control boards. Always verify the supply voltage and output type (NPN/PNP) of your chosen variant matches your system's requirements before connecting.
Q: What does the M18 designation mean?
A: M18 refers to the metric thread diameter of the sensor's barrel — 18 mm. This is a standard industrial sensor form factor, meaning you can mount it easily in pre-drilled M18 holes or standard sensor brackets found in most automation and industrial equipment setups.
Q: Is this sensor suitable for outdoor use?
A: The BR Series sensor is housed in a durable plastic body and carries CE and CCC certifications. For outdoor use, please verify the IP (Ingress Protection) rating of your specific unit to confirm it provides adequate protection against dust and moisture for your intended environment.
