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.).

Cam switches for industry CR-CA 012...040 series Switching angles The range of Bremas solution include more than 10.000 electrical diagrams, characterized by different switching angles, number of positions as well as specific customer requirements: Switching angles

BREMAS Line cam switches The Bremas switching system allows the best performances in every application. Its modular design allows to develop customized solution with different latching torques. Any special requirement can be fulfilled by using different combinations of components such as: • Springs with different resistances • Cursors • Latching mechanism • Cams • Shafts Latching Torque CA with special spring 1 CA with special spring 2 CA with special spring 3 CA with special spring 4 Comparison of latching torques between some switches with special springs.

Cam switches for industry CR-CA 012...040 series • Copper contacts • Silver alloy pads • Double break with positive opening • Long electrical life (over 1.000.000 electrical cycles) • Gold contacts for low voltage signals control • Sliding and self-cleaning contacts for occasional maneuvers Standard contact system (optional gold contacts) • Consists of fixed contacts, connected to the terminals, and mobile contacts controlled by springs, cursors and cams • In the standard configuration, there are a spring and a cursor for each mobile contact • For special configurations, can be used more...
