The HARTING Technology Group, Espelkamp, Germany, offers a number of variations of its PushPull connector series, from well-known V4 and V14 variants to M12 circular connectors. They all can be plugged in within seconds. “One click and the secure connection is there,” explained Ralf Klein, Managing Director HARTING Electronics.
PushPull products permit machines, systems and robots to be reconfigured in seconds, and that saves money, he continued. The user simply grasps the connector and pulls to disconnect. And the unit’s locking mechanism ensures safe operation.
With the PushPull series, HARTING is meeting increased customer requirements for the latest in industrial connectors. Industrial connectors must function smoothly under harsh conditions, and the connection must be protected against unfavorable influencing factors such as gases, liquids and vibrations.
The seals used in housings must close flush with a certain pressure in order to produce optimum tightness. In the field of circular connectors, which are widely used in automation, this is achieved by tightening with a defined torque. However, this typically involves the use of a tool. Connection and disconnection take a relatively long time. The tools require a certain amount of space during assembly, which prevents a higher packing density.
Problems also arise if the assembler forgets the correct tool. In this scenario, only the tool provides process-reliable feedback on proper connection.
The M12, which was originally a connector with screw locking, has been used successfully by HARTING in the transportation sector for two years as a PushPull variant. As a result, HARTING now provides the entire M12 round connector portfolio with PushPull compatibility. Thanks to this development, connectors, sockets, wall feed-throughs, PCB connections and other M12 components are all suited for current and future applications.
For example, assemblers and service personnel can soon take advantage of PushPull connections when dealing with circular connectors. During tool-free assembly, an audible click signals that a proper connection has been established. The packing density, for example on switches, can also be considerably increased. This demonstrates HARTING’s response to the current trend of miniaturization, thus meeting the demands of device manufacturers whose housings are becoming ever smaller.
