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.
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 |
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.) |
