Robust optical signalling device for indoor and outdoor applications.


Share this product:


Optical signalling is often required for warning or notifying purposes in particularly noisy areas. The BLK Strobe Light provides clearly visible signals for that purpose. The sturdy housing of ingress protection IP 65 is suitable for both indoor and outdoor applications. The signalling light is available in 5 different colours.

The modern electronics are mounted on a printed circuit board of glass fibre reinforced epoxy resin. A powerful electronic flash tube converts the electrical energy stored in the flash capacitor into high-efficiency light flashes. The weatherproof coated aluminium die-cast housing is equipped with a ribbed cap made of impact-resistant plexiglass. The strobe light is provided with a M20 cable gland for cable diameters of 8 to 12 mm.
