What is Mirror Reflection Photoelectric Sensor Switch?
A mirror reflection photoelectric sensor switch is a type of photoelectric sensor that uses a reflector to detect the presence or absence of an object.
It works by emitting a beam of light from an infrared LED towards a reflector. When an object interrupts the beam of light, the sensor detects the change in the amount of light received by the photodetector. This change in light level is then processed by the sensor's internal circuitry to produce an output signal that can be used to trigger an action or event.
Product Introduction
This photoelectric sensor is able to detect various transparent or semi-transparent objects and operates on a wide voltage range of DC 10V-30V. Typically, it’s used with a reflector and can detect objects within a distance of 10cm to 100cm.
The device is equipped with a learning function button(SmartTune) that allows users to set its sensitivity with the button during initial installation so as to ensure optimal performance. Align the sensor with the reflector, long pressing the SmartTune for over 5s, and release it when the indicators flash alternately, then the setting is successful and users can get the optimal sensitivity.
Besides, lightly pressing SmartTune can switch between normally open and normally closed NPN and PNP types, meeting different scenario requirements. The sensor features short circuit protection, reverse polarity protection, over-current protection, surge protection, and dual independent output protection for safe and reliable use.
Basic Settings
Normally Open (NO) & Normally Closed (NC) Settings
Short press the SmartTune button to set the NO and NC modes.
Status No object detected Object detected NO Stability indicator is on, operation indicator is off, output disabled Stability indicator is on, operation indicator is on, output enabled NC Stability indicator is on, operation indicator is on, output enabled Stability indicator is on, operation indicator is off, output disabled
Note: The stability indicator is green, and the operation indicator is orange. After powering the sensor on, if the stability indicator is steady on, then the setting is successful; if it is steady off, then the setting failed; if the stability and operation indicators are flashing rapidly, it indicates a short circuit output.
Maximum Sensitivity Setting
Type Steps Adjustment Applicable Scenario Reflective 1 Fix the device and the reflector, then with no object detected, long press the SmartTune button until the stability indicator and the operation indicator flash alternately. Suitable for detecting no-reflection transparent or non-transparent objects. 2 Release the SmartTune button to complete the setting. (If the device vibrates, wait for one vibration period before executing this step.)
Installation Diagram
Note: The transmitter should be installed directly facing the reflector, and the distance between the reflector and the sensor should be greater than 100mm.
The lead wire is 2m pure copper flexible cable.
Wiring sequence: brown for positive, blue for negative, black for PNP, and pink for PNP.

Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
- Short circuit protection
- A safety feature that helps protect the device if its output or wiring is accidentally connected in a way that causes excessive current flow. This matters in automation wiring because mistakes or damaged cables can otherwise destroy the sensor or power supply.
