Connector combines rapid termination technique with high mating cycle capability

The Han ES Press HMC (high mating cycles) connector series from Harting allows for quick installation without tools. The connectors are also robust enough to handle at least 10,000 mating cycles, says the company.

The quick connect technology used in the Han ES Press HMC involves the contact inserts being equipped with a pre-tensioned cage clamp which is triggered by an actuator.

If the actuator is pushed into the contact chamber, the cage clamp returns to its original position and secures the conductor end. Releasing the connection just means pushing a screwdriver into the actuator and moving the lever to the transition to the insulating body.

The spring then releases the end of the conductor once again – for de-installation or when replacing components, for example.

The suitability of the Han ES Press for a high number of mating cycles has been achieved by fitting the contact inserts in Han standard housing sizes 6B to 24B.

The standard housings are already available in versions with locks and seals optimised for high mating cycles. Complementing this arrangement, the contacts and grounding elements are resistant to abrasion owing to a special surface coating.

Harting emphasises that a key benefit of the Han ES Press series is its ability to withstand vibrations well, which results from the tightness with which the conductor fits as a result of the constant pressure of the cage clamp.

In addition, the company says that installation and connection times are reduced when compared with conventional cage clamps, screw connections or hard wiring techniques. On-site installation time is reduced, and the ability for rapid disconnection aids servicing.

The Han ES Press HMC is said by the company to be particularly suitable for test and measurement applications where a test installation may often be hooked up to different power sources, such as portable machinery and devices.

The use of HMC connectors is also worthwhile for machines and systems where frequent reconfigurations and tool changes take place. Han ES Press HMC ensures that users can design their machine inventory for further modularisation.
