Product description

The Allen Bradley 440T-MRPSE100A is a safety pull-key switch designed for robust machine guarding applications. It functions as an interlock device, requiring a key to be pulled to release a guard or disengage a safety mechanism. This ensures that machinery cannot be operated when personnel are accessing hazardous areas, thereby enhancing safety.

This pull-key switch is critical for applications requiring a positive mechanical lock on access points, commonly found in heavy industrial machinery, presses, and automated manufacturing cells. It helps operators ensure that guards are properly closed before starting equipment.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation parts, offers the Allen Bradley 440T-MRPSE100A. Secure your facility's safety with reliable components from Stanlo Automation.

Frequently asked questions

How does the pull-key mechanism on the 440T-MRPSE100A enhance safety?

The pull-key mechanism ensures that a key must be intentionally pulled to release the guard interlock. This physical action prevents accidental opening of guards during operation and ensures that the guard remains locked until a deliberate action is taken, contributing to higher safety integrity.
