FAQ

Q1: What is the difference between a laser displacement sensor and a laser distance sensor? ❯

Laser displacement sensors focus more on high-precision detection of distance changes, while laser distance sensors are better suited for absolute distance measurement. In industrial applications, the choice between the two depends on the required accuracy and measurement range.

Q2: What interfaces do laser displacement sensors support? ❯

The laser sensors typically support communication interfaces such as TTL, RS232, and RS485, allowing them to connect to PLCs, industrial control systems, or embedded devices. The RS485 interface is suitable for long-distance transmission and environments with high levels of interference.

Q3: How do I select a laser displacement sensor? ❯

When selecting a sensor, you should consider the actual measurement distance, the target’s reflectivity, and the installation environment. It is recommended to choose a model with a measurement range slightly greater than the actual distance required. For example, if you need to measure 80 meters, you should select a 100-meter version to ensure stability.

Decent laser displacement sensor, didn't disappoint

Grabbed a pair of these 100m units for our crane setup last month. Honestly? Solid choice. The red laser beam stays super sharp even across the bay. It just does the job without any weird signal drops. Housing is heavy plastic but takes a beating fine. Good price compared to what Germany brands charge.
