SL-200QDM/350QDM/650QDM series is the most advanced long range photoelectric detector. In addition to quad beam and double modulation, our unique technology automatic transmit power control decreases falese and missed alarms. LED Indicator and sound assist and upper/lower beam selection button lighten your workload while achieving perfect alignment.
SL-200QDP/350QDP/650QDP series is standard long range photoelectric detector. In additon to basic feature such as quad beam /double modulation, sunshine protection technology and beam power control selector decreases falese and missed alarms. LED Indicator and sound assist(receiver only) and upper/lower beam selection button lighten your workload while achieving perfect alignment.

Sniper view finder
[X2 MAGNIFICATION LENS] The new telescope lens has a high level of visibility for optical alignment work. Even over long distances, a perfect installation and stable performance can be achieved in a short period.

Double modulation (SL-QDM/QDP only)
The SL-QDM and SL-QDP offer 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.

A.T.P.C.-Automatic transmit power control (SL-QDM only)
Automatically controls, adjusts and optimizes the power of the beam and maintains optimal performance. It decreases false and missed alarms caused by fog, frost, cross talk, signal saturation.

QUAD beam & united appearance
By employing quad beam, it dramatically reduces false alarm caused by birds and falling leaves. Moreover, it is also important that the housing design of both long and short beams are united. 60 m (200 ft.) range models, SL-200QN/SL-200QDP/SL-200QDM with a wide beam pitch is now available.

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.
