IEC/EN 60947-5-1. SL7 modular signalling towers from Eaton. The SL7 modular safety tower from Eaton increases the safety, productivity and availability of your machines and equipment. These new signal towers with their attractive rounded shape also feature a 100 dB acoustic module for improved audibility and IP66 rated mounting components that are impervious to even powerful water jets. The new quick mounting and wiring system of the SL7 signal towers makes it possible to change the composition of the individual signal colours quickly and easily. The mounting adapter uses a bayonet mount so that the electrical wiring only needs to be connected once, i.e. the lower part can remain on the machine. Various mounting options are available for applications with limited ceiling clearance or where different signals are required on the left or right side.
