The Invisi-Guard™ PHT2 Thru-Beam
Photo Eye for Vertical Lift Gates
*Invisi-Guard PHT models have been recently discontinued but, are still supported.
PHT models are now replaced by IG2.
Use two PHT2 on vertical
lift gates so that both sides are guarded: install the 1st
inside the area and the 2nd outside the area. As vehicles approach from either direction, the beam of light is interrupted signaling the gate arm to reverse.
The system includes two independently housed units: an infrared emitting eye
and a receiving that wire directly to your controls.
To provide your customer with an ideal solution, add UL325 tested gate
edge sensor to the gate itself.
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
of this guide, please email firstname.lastname@example.org.
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.
