AB 1411-2SHT-201 Safety limit switch

Allen-Bradley 1411-2SHT-201 Overview

The Allen-Bradley 1411-2SHT-201 is a safety limit switch from the Bulletin 1411 series. These switches are designed to monitor the position of machine guarding (such as safety gates and guards) in industrial automation and machine safety applications. They provide reliable contact operation to help ensure the safety of personnel and equipment.

Product Detailed Description

• Function:

• Monitors the position of safety guarding (e.g., hinged safety doors, sliding guards).

• Triggers switch contacts through mechanical action when the safety guard is opened, interrupting the machine's power or initiating a safety interlock circuit.

• Provides safety contacts (typically Normally Closed - NC) that are closed when the safety guard is closed, allowing machine operation, and are forcibly opened when the safety guard is opened, stopping the machine or preventing it from starting.

• Forced guided contact design complies with safety standards, ensuring reliable opening of the safety circuit even in case of a fault.

• Features:

• Hinged safety switch designed for direct mounting on the hinge side of a safety gate.

• Compact design for easy installation in space-constrained areas.

• Rugged industrial housing to withstand harsh industrial environments.

• Available with multiple contact configurations to meet different safety circuit requirements.

• Complies with global safety standards such as ISO 14119.
