Supported Applications
The Omega OM-AMPB series consists of non-metallic fiberglass pushbutton enclosures rated NEMA 4X (IP66). These units are designed to insulate and protect electrical controls and components in both indoor and outdoor applications. The product overview identifies the series as especially well suited for higher temperatures and corrosive environments.
Operating Conditions & Performance
The enclosures feature a fiberglass reinforced polyester formulation housing that is UV stabilized for outdoor use. They carry UL 94 Flammability Rating, UL (C US), CSA, and RoHS certifications. The series operates within an ambient temperature range of -35 to 130°C (-31 to 266°F). A stainless steel continuous hinge is included as a standard feature.
Configuration Options
The OM-AMPB series supports configurations for both 22 mm and 30 mm pushbuttons. Model numbers follow the pattern OM-AM<#>PB - <NUMBER OF PUSHBUTTONS>, with a suffix added to denote hole size (e.g., adding "22" for 22 mm button holes). The series offers flat cover screw closure models ranging from single-button units up to enclosures accommodating 42 pushbuttons. Dimensions vary by model, with heights spanning from 6 inches to 18 inches and widths from 4 inches to 16 inches.
Key configurable options include:
- Hole Size Configuration: Models are available for standard hole sizes; adding "22" to the model number designates compatibility with 22 mm pushbuttons at no additional cost.
- Mounting Hardware: Mounting feet are included on models configured for four or more buttons. The series offers optional sub-panels and includes 304 SS hardware as an option.
- Hinge Type: All units feature a stainless steel continuous hinge.
Key Product Differences
Variants within the OM-AMPB series are distinguished by physical dimensions and pushbutton capacity. The "To Order" specification table lists specific model numbers corresponding to button counts, such as OM-AM1PB (1 button), OM-AM3PB (3 buttons), up through OM-AM1868HP42 (42 buttons). Depth dimensions vary across the series, with values of 3.63 inches for smaller models and depths ranging from 4 to 8 inches for larger multi-button configurations.
The series also includes specific steel sub-panel accessories listed by enclosure size compatibility, including SCE-6P6 through OM-P186. Ordering examples in the documentation illustrate how model numbers combine capacity and hole-size designations (e.g., OM-AM3PB22 for 3 buttons with 22 mm holes).
