Miller Edge IG2-B1 Protective Boot Covering for IG2 Eyes
The Miller Edge IG2-B1 is a protective boot covering for Miller Edge Invisi-Guard-2 photo optic sensors. It is used when the IG2 emitter or receiver needs an added layer of protection around the housing, especially on gate openings, commercial doors, parking areas, and other locations where the eye may be exposed to weather, debris, or light contact.
This boot is not an electronic replacement part and will not correct a failed emitter, receiver, weak battery, misaligned beam, or wiring problem. It is a protective accessory that should be fitted to the correct IG2 sensor body. Inspect the existing eye carefully before ordering, because older PHT Invisi-Guard parts and other Miller Edge photo eyes may not use the same cover style.

Technician Note
If an IG2 eye repeatedly loses alignment after the boot is installed, check that the boot is fully seated and the mounting bracket was reassembled correctly. A tight or twisted cover can pull the sensor slightly off line.
Before Ordering
- Confirm the photo eye is a Miller Edge IG2 / Invisi-Guard-2 sensor.
- Inspect the existing eye for cracked housing, water damage, or failed LEDs before ordering only a boot.
- Confirm whether one cover or a pair is needed for the job.
- Make sure the boot will not block the lens opening or alignment indicators.
- Recheck beam alignment and safety reversal after the boot is installed.
Professional Advisory
Photo eyes are part of the entrapment protection system. Do not bypass or defeat photo-eye inputs to make an operator run. If the gate or door will not close after service, have the alignment, wiring, monitored/non-monitored setting, and operator safety inputs checked by a qualified technician.
Product Questions and Answers
Is IG2-B1 an electronic photo eye replacement?
No. IG2-B1 is a protective boot cover. It does not include the emitter, receiver, circuit board, batteries, or wiring.
What does the IG2-B1 boot protect?
It adds protection around compatible Miller Edge IG2 photo eye housings and can help shield the sensor body in harsh or exposed installations.
Can this boot fix a misaligned photo eye?
No. A misaligned IG2 photo eye must be realigned and tested. The boot is only a protective cover and should not be used to force a sensor into alignment.
Does the boot fit both the emitter and receiver?
Miller Edge installation literature shows the optional boot being used with the IG2 emitter and receiver, but the existing sensor body should still be checked before ordering.
Will IG2-B1 work with other Miller Edge photo eyes?
Do not assume it fits other Miller Edge photo eye families. It should be used with compatible IG2 / Invisi-Guard-2 photo eyes unless the manufacturer confirms another fitment.
