Essential Info

The AX-100Plus is the next step in outdoor detection, providing the innovative features and flexibility discerning homeowners demand. Optex's unique technology and design provide a wide range of functions that greatly simplify installation and maintain reliable performance even in many adverse weather or environmental conditions.

Twin synchronized pulsed beams provide greater stability and an adjustable beam interruption period help prevent false alarms. An automatic gain control circuit and fine angle adjustment help you fine tune the unit to your application.

For a sensor unit to go with the AX-100Plus, please see the Optex AX-100TF.

Also available in 200 foot range.


More Info

Twin Synchronized Pulsed Beams Designed for Greater 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.

99.5% Beam Blocking Stability
Enables stable operation with as much as 99.5% loss of beam energy caused by heavy rain, dust storms, fog or snow.

A.G.C. (Automatic Gain Control) Circuit
The A.G.C. Circuit continually monitors for gradual changes in the signal's strength caused by changing weather conditions. It adjusts the sensitivity accordingly to maintain the proper signal level for the current environmental conditions.

Adjustable Beam Interruption Period
The Beam Interruption Time (the amount of time a beam must be broken for an alarm to occur) can be adjusted to fit any application. 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.

Lightning & Surge Protection
An improved EMI surge absorber and high surge resistiveness relay will maintain stable operation even in the most lightning prone areas.

High Grade Aspherical Lens
The high grade aspherical lens creates more sharply defined &
precise infrared beams compared to ordinary fresnel lenses.
