Information About 3SE03-BR1
The 3SE03-BR1 is a Siemens metal modular limit switch designed with a side rotary operating mechanism for mechanical position sensing. Siemens documentation identifies this configuration as the standard double-pole version with 2 normally open and 2 normally closed contacts, combined with the 3SE03-DR1 side rotary operating head. The switch uses a plug-in construction and a 1/2-inch NPT threaded opening, while the operating head can be configured for clockwise or counterclockwise operation. Its metal housing and broad enclosure protection make it suitable for industrial machinery and equipment control applications.
Key Features:
- Side Rotary Actuator: Uses a side rotary operating head for detecting mechanical movement and position changes.
- 2NO + 2NC Contacts: Provides two normally open and two normally closed contacts for flexible control-circuit switching.
- Modular Plug-In Design: Uses Siemens' modular 3SE03 construction for convenient integration with compatible components.
- 1/2-Inch NPT Entry: Includes a threaded 1/2-inch NPT connection for industrial wiring installation.
- Metal Housing: Rugged metal construction is designed for demanding industrial control environments.
- Wide Voltage Rating: Rated for applications up to 600 VAC and 300 VDC under specified conditions.
- Enclosure Protection: Available specifications list NEMA 1/3/3S/4/4X/6/6P/11/13 and IP67 protection.
- Rotary Direction: The side rotary mechanism supports clockwise and counterclockwise operation.
The 3SE03-BR1 delivers the reliability and precision required for industrial machinery, position monitoring, equipment control, and automated switching applications.
