CNTD CSA-081 Coil Spring Limit Switch

Product Overview

The CNTD CSA-081 is a versatile limit switch from the CSA series, featuring a flexible coil-spring actuator that detects moving objects from almost any approach direction. The long 50 mm spring probe tolerates misalignment and side impacts that would damage rigid levers, while snap-action 1NO+1NC double-break contacts are rated 10A / 250V AC. The housing combines reinforced plastic with an aluminum cast base for high mechanical strength and is fully sealed to IP65 against dust, water and oil. Certified to EN 60947-5-1 with CE and TUV approvals, the CSA-081 fully complies with European industrial standards.
