Siemens 3SE2 200-1E Limit Switch

Siemens 3SE2 200-1E limit switch is a roller-lever, 1NO+1NC safety limit switch designed for industrial control, with a thermoplastic housing and a voltage rating suitable for switching up to 230 VAC. The 200-1E variant is part of the 3SE2 family and provides one normally open and one normally closed contact, enabling straightforward signaling for machine guarding and position sensing. Its roller lever actuator engages with moving parts to actuate the switch, while the thermoplastic construction supports typical industrial environments. In practice, the 3SE2 200-1E is commonly used wherever a compact, reliable limit switch with a roller lever is needed to detect travel limits, enable interlocks, and feed safe-position signals into control logic—backed by Siemens and distributor datasheets that list 3SE2 200-1E as a NO/NC variant rated for up to 230 VAC.
