WFL

The perfect sensor for the detection of very small parts and precise positioning

Your Benefits

  • A highly precise laser beam ensures consistent measurement accuracy along the entire measuring range and reliable detection of extremely small objects
  • A visible laser beam enables easy alignment and fast adjustment
  • Reliable and simple setting via teach-in button ensures high process reliability
  • A wide range of different fork sizes increases mounting flexibility
  • Stable aluminum housing for use in harsh industrial environments
  • Thanks to IO-Link or external teach-in, the switching threshold can be adapted while the process is running, increasing process reliability
  • Easy to access data from the PLC via IO-Link

Overview

The perfect sensor for the detection of very small parts and precise positioning

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.
