CR-CA Series - Overview

BREMAS Line cam switches

CR-CA Series - Overview Ambient conditions • Designed to withstand very severe conditions of use up to +55°C • Operating ambient temperature -25°C ÷ +55°C • Storage ambient temperature -30°C ÷ +70°C • Withstand to constant and cycling humid according to IEC 60068 Bremas is able to meet any application requirement through the use of special materials, such as stainless steel, metal alloys and plastics even in environments which demands for specific construction requirements (eg. UV resistance, higher self-extinguishing degree, higher mechanical strength etc.).
