See-Through HMI Covers for Enclosures


Cover Shown Mounted on Enclosure

Door Holder Shown Installed

Monitor HMI covers make it easy to access HMI devices, push-buttons, and other electronics mounted on the exterior of an enclosure through a clear window without opening the cover. These covers make it easy to view and access components while keeping contents safe from water, oil, dust, and weather.

Quick-Release-Latch Closure, Slotted-Latch Closure, and Twist-Latch Closure—Covers with a quick-release, slotted, or twist-latch closure offer easy access without the need for keys or removing screws.

Screw Closure, Tamper-Resistant-Screw Closure, Key-Lock Closure, and Two-Way-Key Closure—Covers with screws, tamper-resistant screws, a key lock, or a two-way key closure add security and protect components from unauthorized changes. These covers are not ideal for applications requiring frequent, easy access to enclosures.

316 Stainless Steel Cover—316 stainless steel covers are highly resistant to corrosion, so they’re good for washdown environments. They’re not as durable as steel.

Steel Cover—Steel covers are more durable than 316 stainless steel covers.

Polycarbonate Cover—Resist dents, scratches, and cracks.

2 3/4" Deep and 3 1/2" Deep—2 _3/4”, 3 _7/16”, and 3 _1/2" deep covers have raised covers for additional space, making them best for shielding large components.

UL 746C f1—Block harmful UV rays to prevent screen discoloration, even in direct sunlight.
