PHT1*

The Invisi-Guard™ PHT1 Thru-Beam Photo Eye

*Invisi-Guard PHT models have been recently discontinued but, are still supported.
PHT models are now replaced by IG2.

PHT1 includes two independently housed units: a battery powered infrared
emitter and a receiver that wires directly to your controls. The battery
powered emitter saves time and money by eliminating the need to saw
concrete or run wire across the opening. The built-in audible low battery
alarm alerts users when it is time to replace batteries.

PHT1 has been independently tested to comply with the UL325 standard for gate safety. It is suitable for indoor or outdoor use and distances up to 30 ft.
