LR-T series – All Purpose Laser Sensor

Laser sensor capable of stable detection regardless of target (detectable distance: 6cm to 5m)

1.Superior Detection Capabilities

Superior Detection CapabilitiesThe LR-T is designed to detect at long ranges while remaining highly stable. This is achieved due to the HS2 technology used, a combination of Time of Flight detection and a custom integrated circuit. Additionally, the interference prevention and Datum Function allow users to maximize this sensors capability in any situation.

 

2.Easy to Use

Easy to UseThe LR-T Series is simple to install and calibrate. Flexible mounting options, a visible beam spot, push button teach, and an easy to read display allow for quick setup. Even at long distances, constant feedback is provided with the LR-T’s highly visible status indicator.

 

 

3.Unmatched Versatility

Unmatched VersatilityThe 5m (196.85”) range of the LR-T allows the sensor to be mounted away from operators or machinery keeping it out of harm’s way. Furthermore, an adjustable beam spot allows users to fine-tune the sensor from any distance.

 

 

4.Product Applications

Product ApplicationsA large variety of applications are possible with the LR-T. Examples include level sensing, web tension control, and general conveyance detection.

 

 

 

5.Increased accessibility with easily attachable controller:

The MU-N Series controller provides a remote display that can be used to quickly calibrate and easily monitor attached sensors. This controller pairs perfectly with the LR-T Series, which can be mounted further from targets and in potentially hard to reach positions, due to its long range detection capabilities.
