Push-pull system increases installer productivity

TE Connectivity (TE) has announced that it is extending its M12 portfolio of connectors and cable assemblies with the introduction of its push-pull system technology. The new push-pull variant saves time, is backwards compatible and doesn’t require additional tools to be installed — streamlining the entire M12 installation process. 

“M12 Push-Pull system provides a slim, fast and reliable solution which helps reduce assembly times while providing dependable and secure connections,” explained Ted Szarkowski, TE product manager. “Device manufacturers and system integrators can realise a rapid return on investment due to higher worker productivity and increased production uptime, with less risk of intermittent or loose connections.”

Installing M12 components with the push-pull technology can provide time savings of up to 75%. This is because it can be installed reliably by hand without the need for additional tools or a clear line of sight to the connection. The locking technology provides haptic and acoustic feedback to ensure a solid connection. In addition, the push-pull technology locks inside the mechanism to provide mechanical stability even under torsion stress — providing a reliable connection in a fraction of the time. 

“The M12 push-pull locking mechanism allows fast and secure locking and unlocking by only requiring the same outer space as standard screw type versions,” said Szarkowski. “The positive locking design of the connectors eliminates connector-related intermittent signals in even the harshest environments. Fewer intermittent signals mean less downtime and better productivity.”

Compliant with the IEC global standard

The M12 connectors market is highly fragmented, increasing the importance for a global standard. To ensure compatibility with designs all over the world, the push-pull interface is IEC compliant. “An important advantage of this design is that it’s compatible with standard M12 connectors,” said Szarkowski.

The push-pull technology meets the IEC 61076-2-012 specifications for circular connectors with inner push-pull locking according to IEC 61076-2-101, 109, 113 and IEC 61076-211 2-111.

Additional details

In addition to IEC compliance, the push-pull system meets the UL 2238 standard for cable assemblies and fittings for industrial control and signal distribution, and the UL 1863 standard for communications-circuit accessories. It also has an IP67 rating for resistance to intrusion of dust and water, ensuring efficient, high-quality and reliable connectivity with a high integrity signal transmission.

The M12 push-pull system includes a low-profile female receptable, compact panel-mount receptacles, cable assemblies and field installable connector solutions. It provides a safe, reliable connection of sensors, actuators and other control devices while remaining compatible with standard M12 connectors.
