PHT1SP50*

The Invisi-Guard™ PHT1SP50 Thru-Beam Photo Eye

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

The system includes two independently housed units: an infrared emitting
eye and a receiving that wire directly to your controls. The light beam is
intended to function as a protective line guarding a potentially hazardous
zone. When the light beam is interrupted by an obstruction, a signal is sent
to the motor controls to stop or reverse motion.

Safety Standards and Codes for Motorized Gates:

Miller Edge offers a convenient guide to help you comply with the ANSI/UL325 standard for gate entrapment protection devices. To request a printed copy

Before designing or motorizing any gate, be sure to read and understand the 
ASTM-F2200 standard for gate construction.

Since 2009, the International Building Code (IBC-2009) has required compliance 
with the current UL325 safety standard.
