Banner Engineering, a world leader in non-contact sensors and machine safety products, has been represented in South Africa for the past 18 years by RET Automation Controls.
The latest release from Banner is a Laser Distance Measuring Sensor that uses time-of-flight (TOF) technology. The LT3 has a range of 5m when sensing directly onto the object or 50m when used in a retro-reflective mode. The analogue and digital outputs are set up using a simple 'teach' procedure for each output, with a maximum resolution of 1mm.
TOF technology entails the LT3 sending out one million pulses of laser light each second, its microprocessor then measuring the time for the signal to return and averaging one thousand of the returned pulses each millisecond to provide extremely precise measurement data.
