FAQ

What is the principle of operation for this sensor?

This is a diffuse reflection sensor with background suppression. It uses triangulation to detect an object at a set distance, reliably ignoring any people, machine parts, or reflective surfaces located beyond the set range.

What do the “BN” and “BK” wire color codes on the label signify?

These are standard industrial wire color codes. BN (Brown) is for the positive power supply (10-30V DC), and BK (Black) is the switching output (Q).

Is the large grey connector a standard M12 or M8?

No, this is a non-standard rectangular industrial connector, likely a Harting or similar type. It is designed for a specific machine interface, offering a more secure and robust connection than standard M-series connectors.
