WF Laser fork sensors are characterized by fast response times and a highly focused visible laser beam. The sender and receiver operate using a through-beam design and are in a single housing. No adjustments therefore need to be made. The sensors guarantee exceptionally high positioning accuracy and impress with their extremely fast response times and very fine resolution. As a result, the sensors are particularly suitable for detecting extremely small objects such as needles or wires. They are also recommended for the detection of transparent objects. A total of 21 WF Laser variants are available for use in a wide range of applications.
