AR-043 Explosion-Safe LED Signal Light

AR-043 Explosion-Safe LED Signal Light

The AR-043 is an omnidirectional explosion-safe LED signal light designed for use in hazardous gas and dust environments classified as Zone 2 and Zone 22. It provides a clearly perceptible visual warning signal and is suitable for use under normal weather conditions.

The unit uses 15 latest-generation LEDs and can operate either continuously or in blinking mode at a frequency of 1 Hz, depending on the selected configuration. The signal light is available in red, yellow/amber or green.

The AR-043 can be supplied with a radial cable connection or, on request, with a bottom cable connection. This makes it particularly suitable for installation as a warning light on control cabinets. A fixed 5 metre connection cable is supplied as standard.
