These infrared photobeam curtain/barrier sensors are ideal for mounting in areas with limited space such as windows, doorways, skylights, and fence tops.

They are well-suited for both indoor and outdoor perimeter security. The triggering mechanism can be programmed to simultaneously detect the breaking of either a single beam or two adjacent beams. The sensors boast a robust aluminum build and incorporate an anti-tamper circuit that triggers an alarm in the event of power loss or if the end cap is tampered with.

These sensors do not necessitate synchronising wires, and their installation is facilitated by an LED alignment indicator. Additionally, L-brackets and mounting hardware are provided for your convenience.
