Double modulation


The SL-QDP-BT offers double modulation beams that differ in pulse patterns. This can enhance signal discrimination against potential noise interference such as sunlight or other external light sources, resulting in a reduction of missed alarms. Together with OPTEX triple layered sunshine protection technology, it ensures high reliability under the severe outdoor security environment.

Beam power control selector


It allows you to manually adjust beam power from NORMAL to LOW or VERY LOW. This function is effective for the following purposes:
For countermeasure against crosstalk due to reflection ofwall or floor by reducing beam power.
For countermeasure against interference due to unstable S/N (signal / noise) ratio when using multiple photo beams for long distance or beam stacking applications.
To reduce beam power when using the detector for a distance shorter than the rated distance.
To search the peak value when making optical alignment to support perfect alignment.

Wireless-Ready


SL-350QFR-BT, our wireless ready, battery operated photoelectric detectors are designed to work with most manufacturer`s wireless transmitters, and the back box has enough space to accomodate them. They are easy deployable and adaptable to any control systems currently installed.
