Waterproof Mirror Reflection Photoelectric Sensor Switch (10~100cm)

This is a wide-voltage (DC 10V~30V) sensor designed for detecting various transparent or semi-transparent objects. When paired with a reflective mirror, it delivers a detection range of 10cm to 100cm.

The device features a learning function for initial sensitivity calibration via the SmartTune button: align the sensor with the reflective mirror, press and hold the setting button for more than 5 seconds, and release when the indicator lights flash alternately to complete the setup.

The SmartTune button also supports switching between output modes: NPN Normally Open (NO), NPN Normally Closed (NC), PNP Normally Open (NO), and PNP Normally Closed (NC), to adapt to different application scenarios. It is integrated with short-circuit protection, reverse polarity protection, over-current protection, surge protection, and independent dual-output protection for safe and reliable operation.

A new timer function is added to enable delayed turn-off of the output signal. For example, when controlling relay switching, the relay needs to remain energized for a period to allow equipment to start properly before disconnecting — a requirement that traditionally requires a PLC, timing module, or high-end fiber optic sensor. This sensor integrates a simple "off-delay" timer to fulfill this function directly.

Basic Settings

Note: The new version adds the timer function. The NO/NC mode setting has been changed from a single press to two short presses of the SmartTune button.
