AR-047 LED Signal Light

AR-047 LED Signal Light

The AR-047 is an omnidirectional explosion-safe LED signal light designed for use under demanding industrial conditions. Its robust AISI 316 stainless steel housing and top plate, 20mm impact-resistant polycarbonate window, silicone seals and encapsulated electronics provide excellent resistance to water and salt.

The latest-generation LEDs provide a clearly visible warning signal. Depending on the selected configuration, the light can operate continuously or flash at a frequency of 1 Hz. The signal light is available in red, yellow/amber or green.

The AR-047 can be supplied with either a radial cable connection or a bottom cable connection, making it particularly suitable for use as a warning light on control cabinets. A fixed 5 metre connection cable is supplied as standard.

The AR-047 is certified by DEKRA Certification in accordance with European Directive 2014/34/EU (ATEX 114) and also complies with the IECEx certification system for explosive atmospheres. It is suitable for use in Zones 1, 2, 21 and 22.

For applications limited to Zone 2 and Zone 22, the similar AR-043 LED signal light is available.
