Sick releases laser fork sensors
A
SICK (UK) product story

Position detection with high accuracy and reliability is available from Sick's WFL laser fork sensor range.
The WFL is suitable for many automated guidance and control operations, and its very high- speed response is ideal for precision production line duties, including printing, packaging and labelling.
The WFL range uses an extremely accurately focused laser sender and receiver, on either arm of a precisely and robustly manufactured housing, to detect movement across the beam.
The housing is mounted so that the items to be detected pass between the arms, breaking the beam and sending a signal to the system control.
The system detects even very small objects such as needles, and transparent objects including bottles and blister packs.
Glass optics and metal construction ensure a long reliable life, immune to dust, dirt and vibration.
The range of WFL 21 sizes includes gap widths between the arms from 2mm to 120mm, and arm lengths allowing a depth of reach from 40mm to 90mm.
This makes it easy for WFL sensors to be employed across a wide range of applications.
The WFL combines rapid set-up and configuration with simple adjustment to ensure it can be quickly installed in a control system.
Push-button controls are set on top of the arm and allow instant control of PNP/NPN and light/dark switching.
