Hammond Manufacturing R100 Type4X Diecast Aluminum Enclosures are watertight, thick wall enclosures with NEMA 4X, IP66, DIN 40050 degree of protection. R100 Diecast Aluminum Enclosures feature a single-channel fastening system that provides a larger interior space than dual-channel enclosures. The single-channel system uses the same enclosure hole for mounting the enclosure and fastening the lid. These Hammond enclosures have a shallow lid and deep body with captive stainless steel lid screws. The series handles a -40°C to +80°C temperature range.
