Safe access protection specialist, Sick Sensor Intelligence has released the DMM4, a configurable muting module designed to ensure the safety of personnel while in the vicinity of hazardous machinery.

Muting – or the temporary automatic suspension of a safety function by way of safety-related parts of the control system – aims to achieve continuous, efficient material flows, while protecting people from hazards.

Also used in manufacturing, the DMM4 is suitable for the muting of automated guided vehicles (AGVs), electric forklifts, and autonomous mobile robots (AMRs) in the logistics sector.

In the case of a safety light curtain, sensors and process signals can safely identify materials to initiate a mute and allow the product to pass through without stopping the system.

According to Sick, the DMM4 muting module meets industry standards for safe material flow through electro-sensitive protective equipment (ESPE), and is able to accurately and reliably differentiate between material and people, with the aim of ensuring safe working conditions.

A robust, in-the-field solution with several new features and benefits, the DMM4 is fully compatible with Sick’s deTec safety light curtains and deTem safety light-beam sensors. As such, it is intended to ensure seamless protection and efficiency with easy installation.

“Highly flexible and configurable, the Sick DMM4 is out of the box certified and Plug and Play, with easy installation and connectivity with the Sick deTec safety light curtain,” says Martin Kidman, Sick manager – safety (S&W Europe).

“It’s part of a complete range of Sick safety light curtain products, including light curtains, sensors, fittings and muting modules.”
