IEC 61076-2-010 connector

The M12 PushPull standard for automation

The PushPull locking saves 80% assembly time and simplifies the connection of circular connectors in automation. The IEC standard 61076-2-010 defines all M12 PushPull interlocks for a uniform market standard.

The IEC standard 61076-2-010 finally brings an industry-wide uniform push-pull locking system for circular connectors in factory automation. Slow screwing was yesterday. With PushPull it's: Click & Connect! Simple, fast and reliably connected. Regardless of whether the device socket is vertical or recessed, a PushPull locking system in accordance with IEC 61076-2-010 always gives device manufacturers the right solution from a single source.

Time saving

The PushPull locking system offers a high time saving of approximately 80 percent when connecting the automation components, as screwing is no longer necessary. Calculated over the course of a year, this means that enormous savings potentials can be realised during assembly.


Due to the improved handling, device ports can be arranged more compactly, which corresponds to the desire for miniaturisation and economical cabling.

Safe handling

In addition to saving time, there is no need to check the correct tightening torque of the lock using a torque spanner. The user receives an acoustic feedback that audibly indicates the correct locking - a simple, fast and safe locking.

Backwards compatible

New device sockets with PushPull contour according to IEC 61076-2-010 enable the use of familiar M12 connectors with screw locking or also with PushPull locking. This means that devices can be designed to be backwards compatible.

Dr. Metrix and the rescue of the circular connectors

Our new heroine Dr. Metrix is fast, strong and puts the fear of God into every slow screw locking system. In the twinkling of an eye, she transforms any conventional M12 into a modular PushPull interface and saves our users valuable time. It is the face of the future M12 PushPull standard for the entire factory automation. With a comprehensive solution for vertical and recessed sockets, it is the salvation of automation on the way to modular manufacturing and I4.0.

HARTING's new heroine for circular connectors with PushPull locking.
M12 PushPull for transportation applications

As a technology group in the area of robust connection technology, we established our well-known M12 PushPull solution on the market a long time ago and have created a statutory standard in the area of transportation in particular. When developing the HARTING M12 PushPull, the focus was therefore on robustness from the very beginning.

One standard for all applications

IEC 61076-2-010 describes both internal and external locking by means of push-pull. It contains all variants that are used for a universal system solution in the field of automation technology. The PushPull standard references the IEC 61076-2-1XX basic standards and thus represents a coordinated supplement.

The device connectors are designed rotationally symmetrical just like the proven M12 standard, which means that the push-pull mechanism of the device port does not have to be aligned with the coding of the M12 contact carrier. This gives the device manufacturer a high degree of freedom to design the cable outlets of the ports simply and, above all, economically.

The M12 basic standards and the push-pull standard -010 are also consistent with regard to design-in requirements. This means that a conventional M12 port with a standard thread can be replaced with a port with push-pull functionality - without any constructive intervention in the device design - and this can even be done retroactively for existing device concepts.
Push-pull locking elements can be made of plastic or metal. Overall, the system offers a lot of freedom for device developers in automation. Device manufacturers offer their customers considerable added value by using PushPull quick-locking devices.
