How to Use the Photoelectric Sensor in the Linear Actuator?

The working principle of the photoelectric sensor is mainly based on the photoelectric effect, which converts changes in optical signals into changes in electrical signals to achieve measurement and control functions. These sensors generally consist of three main parts: light source, optical pathway, and optoelectronic components. Usually, photoelectric sensors are used as zero points.
Our linear actuator products will come with at least one sensor. If you need to install more sensors, please contact our sales staff for customization.

The following is the wiring method of the photoelectric sensor:

Connect the power cord, connect the positive pole of the power cord (usually the red wire) to the VCC pin of the photoelectric sensor, and connect the negative pole of the power cord (usually the black wire) to the GND pin.
Connect the output wire, connect the output wire (usually a white or black wire) to the device or circuit you want to control, such as PLC (Programmable Logic Controller), microcontroller, relay, etc. If using relays or similar high power loads, make sure the output wires can handle the required power.
Set the external circuit. Depending on the type of photoelectric sensor and the required functions, you may need to set the input mode of the external circuit to NPN or PNP (as shown below).
Check all connections to make sure they are firm and reliable, and there are no short circuits or loose connections.
