Weidmüller HDC Enclosure is manufactured from die-cast aluminium with powder coating finish. The special die-cast alloy and the multi-layered surface sealing provide complete protection for the HDC housings. The cleverly designed interlock system is manufactured from stainless steel which guarantees a long lifespan with high resistance to corrosion and impact. The unique, patented spring system provides the housing interlock with a secure grip and prevents accidental opening. Each housing is permanently labelled with a laser marking so that each product can be quickly designated and positioned.
