Overview

The Hammond Manufacturing 1550B is a compact, diecast aluminum enclosure designed for industrial control and electrical applications requiring durable, corrosion-resistant protection. Measuring 4.51 inches in length, 2.52 inches in width, and 1.02 inches in depth (excluding lid), this enclosure provides a rugged housing solution in a space-efficient footprint. Constructed from heavy-duty die-cast aluminum alloy, the 1550B delivers robust mechanical strength while maintaining a natural aluminum finish for corrosion resistance and aesthetic versatility. With an IP54 ingress protection rating, the enclosure resists dust ingress and water splashes, making it suitable for indoor and sheltered outdoor environments where moderate environmental exposure is expected. The 1550B is part of Hammond’s 1550 Series, a family of enclosures optimized for control panels, junction boxes, and sensor housings in industrial automation, machinery, and instrumentation applications. Its compact dimensions and material properties allow for integration into tight mounting spaces while ensuring reliable protection of internal components against physical damage and environmental contaminants. The diecast construction provides EMI/RFI shielding benefits, reducing interference in sensitive electronic circuits. Common applications include housing pushbuttons, pilot lights, terminal blocks, and small control modules in manufacturing, automation, and process control systems.
