A-B 42MRU-5000 Central control module

A-B 42MRU-5000 Overview

The A-B 42MRU-5000 is a safety light curtain receiver from Allen-Bradley's (Rockwell Automation) Guardmaster™ safety light curtain system. It is a receiver unit that needs to be paired with a corresponding

 transmitter unit to create a protective zone. When an object (such as a person's body part) enters this zone, it triggers a safety stop signal.

Product Detailed Description

• Function:

• Receives infrared light beams from the safety light curtain transmitter.

• Monitors the beams for obstruction.

• Outputs a safety stop signal when one or more beams are blocked, preventing hazardous machine motion.

• Requires pairing with a corresponding transmitter (e.g., 42MTU-5000).

• Features:

• Part of the Guardmaster™ SB4 series of safety light curtains.

• Provides finger or hand protection (depending on beam spacing and resolution).

• Rugged industrial design.

• Easy to install and align.

• Integrated status indicators.

Product Parameters

• Series:

• Guardmaster™ SB4

• Type:

• Receiver

• Protective Height:

• Depends on the specific system configuration (e.g., may be 500 mm when paired with 42MTU-5000).

• Resolution (Beam Spacing):

• Depends on the specific model, determines the minimum object size that can be detected (e.g., finger protection or hand protection).

• Operating Voltage:
