World's Smallest Time Of Flight Measurement Laser

The TOF-DL time of flight laser is ultra-compact and capable of accurately measuring at distances up to 2.5 Meters.

Time Of Flight (TOF) Method

The TOF method measures the time it takes a pulse-emitted laser to hit a target and return, and the measurement is then converted into distance. With strong resistance to influences from the target’s surface conditions, this method is capable of producing stable detection.

Intuitive digital display for easy Set-up

The TOF-DL Laser is equipped with a 3 digit, easy to see digital display. The display allows users to check the measuring distance. Set-up is also made easy with the push-button teach functions

TOF-DL250A and TOF-DL250AM12 Type wiring

Wiring Diagram. The sensor can be set-up for 4-20ma or 0-10v output. The digital output can be set for NPN or PNP
