Tips for Using Laser Displacement Sensor

The maximum allowable power supply voltage of this laser displacement sensor is 10% of the rated voltage. Please confirm that the power supply voltage is less than the maximum allowable value before powering on.
It takes a certain amount of time for the sensor to be initialized from power on to normal detection. Please make sure that it is used for more than the initialization time after powering on.
When the sensor and the load use different power supplies, please make sure to turn on the power supply of the sensor first.
When the sensor is not in use, it is recommended to cut off the power supply to the load first, and then cut off the power supply to the sensor.
When installing the laser displacement sensor, do not subject the sensor to severe external force (such as hammering, etc.), which may damage the sensor's performance.
Avoid using thinners, alcohol, or other organic solvents when cleaning.

Existing reviews of Laser Displacement Sensor, 50m-400m, 4-20mA/0-5V

Reliable laser sensor

We use the 400mm version for tank level monitoring. The 4‑20mA output is linear and repeatable. Easy to install with the OLED display for setup. IP65 holds up in dusty areas. Very reliable.
