See-Through HMI Covers for Enclosures


Cover Shown Mounted on Enclosure

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.

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, 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.

Polycarbonate Cover—Resist dents, scratches, and cracks.

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.
