Product details:

This is Alarm Two Beam Photoelectric Infrared Detector. Integrated design, installation brackets, the most convenient installation. Holographic spot real-time report. Unique displacing receiving, transmitting parts with big power. Full function checking, self-adaption in environment and trouble locking. Patented balanced checking, unique digital filtering. - Safety Photo Beams For Gate Openers- The Lockmaster photo eyes are a valuable safety feature that will keep the gate from closing when any obstruction is in the path of the photoelectric beam.- The photo eyes use Dual Beam and Through Beam technology, which are more reliable than reflective beams because they do not allow sunlight to create a false reading- The photo eyes need to be direct wired into the gate opener's circuit board with low voltage wire. - Unique optical design: optical glass, beam penetrates the special multi-layer anti-environment (such as rain and snow) and other capabilities - Automatically increase sensitivity when faced with fog or inclement weather - Optional dual aspheric fresnel or secondary focusing lens to achieve a large-diameter light beam - Automatic environment recognition circuit (EDC), avoid reflective interference modular - Horizontal / vertical optical angle easy to adjust, easy to calibrate - High levels of resistance to RFI / EMI capability - Unique digital filter circuit design99% photographic margin - Built-in optical sight - Anti-lightning circuit design - Use of C-type output device - Adjustable beam interdiction cycle is more flexible and adaptable - The integrated structure designed to be able to work in harsh environment - Range30m / 100ft - No.of Beams2 beams - Detection Mode2 beams blocked simultaneous - Optical Source - Infrared digital pulse beam - Response Speed50 ~ 700msec - Relay Contact Output - NO.NCContact Rating - AC/DC30V 0.5AMax - Power Supply - DC 13.8 ~ 24V AC 11 ~ 18V P 15WOperation Temperature-25- 55Operation Humidity5% - 95% RH (relative humidity)Dimension8 x 7.6 x 16.1cm/3.15 x 2.99 x 6.34 inch(L
