Why do we recommend you try the laser photocell YET611LSR?

December 03, 2022

The input voltage of this photocell is AC: 9V~ 24V (AC Frequence: 50HZ/60HZ) and DC: 9V~30V. Its Sensing distance is 0.3m~ 8m and there is no blind spots which is the biggest reason why we recommend this type of photocell . It can work under the temperature -10℃ ~ +60℃ and store under the temperature -20℃ ~ +75℃. The product output interface are GND/AC、VCC/AC、NO/NC and COM.


LED light indication are as follow,

Green LED light: 1) It is mainly used to indicate the power-on status of the product; 2) It is used to indicate the distance setting mode and working mode switching;

Yellow LED light: working status signal indication (On/Off: light off when there is an obstacle / light on when there is no obstacle.)

So you can check the photocell state through the LED light.


Next I would like to introduce Product Operating Instructions to you.

Power on the product, after the power indicator and status indicator flash 3 times, the power indicator is always on, the status indicator is off, and the buzzer makes a short beep, indicating that the boot initialization is successful;

Ø Setting distance:

²1. Enter the distance setting mode: After the product is powered on and initialized successfully, within 10 seconds, the user uses a shield to cover the distance from the product (within 0.5m) back and forth 5 times, until the buzzer

"beep-beep-beep", enter the distance setting mode ;

² 2.The power light will flash continuously and quickly, indicating that the product has entered the state of detecting


² 3.Adjust the position of the product so that the product is within the detection range required by the user; you can also

listen to the number of buzzer sounds (slow sound: 1m/time, fast sound: 0.5m/time) to preliminarily determine the

current product distance. distance between obstacles;

² 4.When you hear a long beep of the buzzer, the power indicator (green light) flashes slowly for 3 times and then stays on,

indicating that the distance configuration is successful, and exits the distance setting mode;

² 5.When you need to reset a new detection distance, please power on again and and repeat the above steps.


When you install this reflective laser photocell,please note below issues,

1.When debugging and installing, make sure that there are no obstacles within the set sensing distance;

² 2.When installing the product, try to avoid direct sunlight;

² 3.The minimum height for product installation is 1 meter, and it is recommended to be greater than 1 meter;

² 4.When setting the sensing distance of the product, it must be more than 0.3 meters;

² Do not power up the sensor until all electrical wiring to the sensor has been completed.


Above are the reflective laser photocell details I would like to introduce to you,for more information,please feel free to contact us.
