WLD or “wireless lateral displacement” sensors are widely used in the industrial market. This type of sensor is able to measure lateral displacements (or lateral movements) to a very accurate degree, making them ideal for use in automation, robotics, laboratory equipment and other applications. The WLD sensor uses a range of technologies including radio frequency (RF), ultra-sonic, optical, strain gauge and force-voice sensor technology. The majority of WLD sensors are also designed to be very rugged, meaning they can withstand extreme temperatures, shock, vibration and corrosion.

Snap Action

Snap action is one of the most common applications of WLD technology. It is typically used on systems with a single axis of movement, such as those used in factory robots. The WLD sensor is able to predict when the system will go into a particular linear position relative to a chosen threshold. When this occurs, the sensor will trigger a signal for the system to take action, such as stopping the robot to avoid crashing. On the other hand, if the system does not reach the predetermined threshold, the signal will not be triggered, allowing the system to continue to move in its desired direction.

Limit Switches

In addition to snap action, WLD sensors have also been used in limit switch applications. A limit switch is a type of switch used to determine when an automated system has reached a certain point. This type of switch is typically triggered when an object passes a certain point, enabling the system to make an appropriate decision. WLD sensors can be used to detect when an object has reached a predetermined point or to sense its distance from the point. When the object reaches the predetermined point or is detected to be at a certain distance away, the WLD sensor will trigger a signal, allowing the system to take action accordingly.

The WLD sensor works by sending and receiving radio waves or sound waves. These waves are picked up by the sensor, which then translates the information into a digital signal and sends it to the system. The system then uses this signal to make a decision, such as if to stop or continue with the operation. The WLD technology allows for a more accurate, consistent and repeatable measurement of movement and distance between objects, enabling automation and robotics systems to run more smoothly and reliably.

WLD sensors have been around for more than 30 years, and have been used in a wide range of applications. As technology continues to advance and new applications emerge, the use of WLD sensors is being adopted in ever increasing industries. Whether it is for measuring precision distance and movement or for providing limit switch capabilities, WLD is a powerful and reliable technology that is here to stay.
