4 Beams Photoelectric Beam Detector (XA-50S)

---Design Durability
Highly Durable and Heat-Resistant Housing Cover and Chassis
The housing and chassis provide higher durability against shocks, high temperatures, and many other harsh environmental conditions
--- Frost and Dew Protection
An anti-frost and convex visor design is incorporated to protect detector from effect of frost and dew
---99.5% Beam Blocking Stability
Stable operation is maintained with as much as 99.5% of the beam's energy blocked by heavy rain, dust storms, snoe or fog
---High Grade Aspherical Lens
The high grade lens creates more sharply defined and precise infrared beams compared to ordinary Fresnel lenses
---Twin Synchronized Pulsed Beam Desisned for Great Stability
And Gate dual beams require simultaneous interruption of both beams to trigger an activation. No activation is generated when a bird or falling leaves break just one beam
---Adjustable Beam Interruption Period
The Beam Interruption Time (the mount of time a beam must be broken for an alarm to occur) can be adjused to fit any applicatin. For example, when protecting a wall or fence, a longer interruption time will catch intruders, but let jumping cats pass through without setting off an alarm
---Quick optical and voltage alignment to speed up positioning
Conveniently placed view finder allows for easy alignment, even in some of the difficult mounting situations. In the receiver there is a LCD Voltage Displayer, it indicates the alignment level
-A. G. C. (Automatic Gain Control )Circuit
The A. G. C. Circuit continually monitors for gradual changes in the single's strengh caused by changing weather. It adjusts the sensitivity accordingly to maintained proper Single level for the current environmental conditions.
