Based in Norway, DNH have been designing and manufacturing loudspeakers for industrial and commercial application since 1946. Below is a selection of junction boxes and beacons designed for use in environments where IP ratings of up to 67 are required for weatherproofing cable connection or visual cue.
BS-21
DNH BS-21 is an IP66 rated beacon flashlight designed for be mounted on the ceiling or a wall whereby a visual cue can be seen.

The lamp type is xenon and the dome is manufactured from borosilicate glass. There are M20 two cable entries, and the unit is delivered with two M20 blacking plugs. Internal termination is via screw terminals.
Rated energy: 21 Joule. Maximum voltage: 48V, DC; 230V, AC 50-60Hz. Dimensions (WxHxD): 98 x 183 x 177mm. Weight: 2.4kg.
BS-21 EExeN
BS-21 EExeN has the same properties as BS-21 however it is an explosion protected version. The terminal block is push-in type, as opposed to screw-in.
