Optical signalling devices for use in noisy environments.


Share this product:


The rotating mirror beacons enable safe and reliable signalling in noisy environments. Indoors the signal is even noticed when the light source itself is not visible because the light flashes are reflected by walls and other objects. The SLD 1 and SLD 2 rotating mirror beacons use H1 halogen lamps 12 V, 55 W or 24 V, 70 W. The caps come in the colours transparent, red, amber, green and blue. The power supply and vibrationabsorbing mounting of the chassis of the SLD 3 rotating mirror beacon make it especially suitable for use on forklift trucks. It comes in two version with a 36 VDC to 60 VDC or 80 VDC to 120 VDC power supply.

The SLD 1 rotating mirror beacon is a version for mounting on horizontal sur faces. It can also be fitted on slightly sloping surfaces (for example top of a car) by placing a DPR rubber gasket between it and the sur face. It can further be mounted on an ASFL extension flange placed on a vertical rod. The SLD 2 rotating mirror beacon can be mounted on an ASTR extension rod. The connection cable then runs through the extension rod. This beacon is intended for use on vehicles and is only avail able for operation on 12 VDC or 24 VDC power supplies
