The plastic surface-mounted housings of the Harmony XALK series are available both as complete housings for direct use and as empty housings for individual assembly. The robust plastic housings made of polycarbonate are ideal for universal use in industry and mechanical engineering. This surface-mounted housing in light gray/yellow has 1 hole of 22mm and is already factory-fitted with 1 emergency stop switch with 1 break contact and 1 make contact. The auxiliary switches can also be flexibly selected between front and base mounting. This complete housing is therefore ideally suited for direct use.
