The new Allen-Bradley Guardmaster 440G-EZ electromagnetic interlocking switch can help protect people, processes and equipment. By providing the physical interlocking of guard doors, the safety switch allows access to a potentially hazardous area only when the area is safe. This can help keep people safe and protect a process from unplanned downtime to improve productivity and efficiency.
The 440G-EZ electromagnetic safety switch uses a power-to-lock (PTL) magnetic locking function, which increases door stability, and reduces misalignment and nuisance tripping. With its high holding force and misalignment tolerance, the 440G-EZ switch is intended for use on all types of guard doors.
The 440G-EZ switch has a low-profile housing design. It has multiple mounting and connection options, including 5-pin or 8-pin M12 micro quick-disconnect pigtails for optimal installation flexibility.
To simplify installation, troubleshooting and maintenance, the switch offers onboard LED diagnostics, indicating switch status when the state of the output signal-switching devices are locked or unlocked.
The 440G-EZ safety switches are TÜV-certified up to Cat 4, SIL 3, PLe – the highest level of safety for guard position.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
