Mini laser sensor

Banner Engineering has introduced the World-Beam QS18LE series laser emitters designed for use as a DC powered 'laser pointer' in an industrial housing as well as the emitter half of an opposed mode sensor pair.

As a pointer, the device provides five different beam shapes including small spot, circle, vertical line, horizontal line and cross for applications requiring precise product or target location.

These applications include pointing at a punched hole or missing hole, as part of a sensor array of 'pick-to-lights' illuminating a component selection work sequence, and for material cut-off indication.

Paired with a photoelectric receiver, the sensors' narrow effective beam provides small object detection and accurate position control.

Its output is modulated to give the laser long life and keep the power band it emits accurate.

High-speed modulation of the laser creates a sensor emitter that various Banner receivers 'recognise' as a modulated emitter.

The visible beam is enabled by applying 0 VDC to the unit's laser control input wire and a beam extinguish function is enabled when +10 to 30 VDC is applied.

Integral circuitry protects the 10 to 30 VDC QS18LE sensors against reverse polarity, over voltage and transient voltages.

There is a 1.5 second delay at power-up and all models include a third wire feature for extinguishing the laser light when +10 to 30 VDC is applied.
