Siemens 3SE5 Series Roller Limit Switch, 2 NO/1 NC, IP65, Plastic Housing, 400V ac, 6A

This switch is a mechanical position device designed for industrial detection and control tasks where robust actuation and environmental protection are required. Housed in a plastic enclosure with increased corrosion resistance and a stainless-steel roller lever, it provides snap-action switching for monitoring moving parts in machinery and automated systems. The unit is suitable for use across a wide ambient temperature range and offers screw-terminal connections for straightforward wiring.

• 15 000 000 cycle life for extended maintenance intervals
• 400V AC switching capability for mains-level control
• 6A switching current for moderate load switching
• 10N actuating force for consistent, repeatable operation
• IP65 enclosure rating for protection against dust and jets

• Suitable for conveyor end-of-travel detection
• Used with actuated guards and machine doors
• Can be used for limit sensing on material handling equipment
• Ideal for control panels requiring positive-opening safety contact
• Used for position feedback in automated assembly lines

A single M20x1.5 cable entry is provided for conduit or gland fitting.

Connections are via screw terminals accepting solid or stranded conductors up to 1.5mm² and two conductors in smaller ranges.

The device achieves around 100 000 electrical cycles at AC-15, 230V operational conditions.

The roller lever uses high-grade steel with a plastic roller to improve durability in corrosive environments.
