Siemens 3SE Series Limit Switch, IP67/IP66, Roller Plunger Actuator Type - 3SE5242-0LD03

This limit switch provides a robust, field-ready sensing solution for mechanical and electrical automation tasks. It detects positional changes via a roller plunger actuator, offering quick-contact operation suitable for industrial environments where compact, weather-resistant switching is required.

Features and Benefits:

• Roller plunger actuator reduces wear for consistent activation
• Quick-action contact enables Rapid state changes with minimal bounce
• Rated switching current 10A for moderate load handling
• Accepts up to 400V DC enabling high-voltage DC control circuits
• M20 conduit entry simplifies secure cable routing in enclosures
• Operates across -25°C to 85°C for varied ambient conditions

Applications

• Suitable for conveyor end-of-travel detection in factories
• Ideal for machine safeguarding on assembly lines
• Used for position feedback in material handling systems
• Can be used for limit sensing on automated doors and Gates

What contact arrangement is provided for control logic flexibility?

The device offers a combination of one normally open and two normally closed contacts to support multiple control and signalling schemes.

How is the unit protected against dust and water ingress?

The enclosure meets high ingress protection ratings, allowing reliable operation in wet or dusty process areas.

What type of electrical connection is used for field wiring?

Internal screw terminals provide secure conductor clamping suitable for common industrial cabling.

How long can the switch perform actuations before mechanical wear becomes a factor?

The mechanical endurance is specified at fifteen million cycles, supporting high-duty applications without frequent replacement.
