A20NTMA2

Overview

The Hoffman A20NTMA2 is a NEMA Type 12 metal enclosure designed for industrial protection against dust, falling liquids, and oil. It features a hinged door with a quarter-turn latch mechanism for secure access. Constructed from steel with a gray powder-coated finish, the unit provides robust environmental sealing. The enclosure includes mounting provisions for internal components and supports standard panel cutouts. Its design facilitates easy installation in control panels or machinery where moderate environmental protection is required.

Feature Summary

• Hinged door design allows for convenient access to internal components without removing fasteners
• Quarter-turn latch mechanism ensures secure closure and reliable sealing
• Steel construction with protective coating resists corrosion and physical damage
• NEMA Type 12 rating offers protection against dust, dripping non-corrosive liquids, and oil

Applications

• Industrial control panels requiring moderate environmental protection
• Machinery enclosures exposed to dust and light oil splashes
• Electrical component housing in manufacturing environments
• Automation system integration where quick access is needed

Procurement Notes

Verify that the specific application environment aligns with NEMA Type 12 limitations, as this enclosure does not provide watertight or submersible protection. Confirm dimensional requirements match the available space constraints. Ensure that the mounting hardware included meets local safety standards. Check for any additional accessories such as gaskets or knockouts that may be required for specific cable entries. Review the manufacturer's datasheet for precise weight and material specifications before finalizing procurement.

Selection Notes

Select this model when a hinged door configuration is preferred over removable doors for frequent access needs. Consider the internal volume requirements to ensure adequate space for components and wiring. Evaluate the need for additional features such as ventilation fans or heaters if thermal management is critical. Compare with NEMA Type 4X options if higher levels of water or washdown protection are anticipated. Verify compatibility with existing mounting structures and cable entry points.
