Model RLS24-P: Rugged Laser Sensor with removable 3 meter cable, water tight M12 connector to 1/8" phone plug connector, mounting bracket with jam nuts and 12 inches of T-5 tape (10-24Vdc input power).

We’ve taken our hugely popular Remote Optical Laser Sensor (ROLS) and packaged it in a Rugged 316L SS IP67 rated enclosure. Although optical speed sensors require atmospheres that are clean and free of mist, steam, dirt, oil and other contaminants in order to function properly there are times when contamination can occur accidentally. Our Rugged Laser Sensor will survive these unintended episodes. Simply clean off the laser and detector windows and your up and running again. The RLS utilizes a water tight M12 connector that facilitates easy removal for cleaning. With an operating range of up to 25 feet, the RLS can be used in applications where close proximity isn’t convenient or safe. The laser light source makes setup incredibly easy. Simply aim the laser at a reflective tape or high contrast target and you’re ready to start measuring. The sensor has an on target Indicator built in to confirm that the sensor is detecting the target. The RLS is supplied with a 3 meter cable with choice of tinned flying leads or 1/8” phone plug connector for use with all of our portable tachometers and stroboscopes. You can also extend the cable length by adding our 25 foot extension cable(s).
