Harting is promoting its recently launched HAN ES Press contact inserts that benefit from tool-free quick connection technology. These inserts reduce assembly time by up to 50 per cent and, in addition, plug-in jumpers offer the possibility of quick and simple potential multiplication or star/delta configurations within the connector. HAN ES Press contact inserts are equally suitable for assembly in a production environment or in the field.
The secret of the design lies in an innovative cage clamp. The HAN ES Press cage clamp is delivered open so the conductor can be inserted directly and without the need to open it first. Once the the actuator has been pushed into the contact chamber, the cage clamp fixes the conductor end so that it is electrically connected to the contact. This connection technique permits faster termination during wiring, and an audible and tactile 'click' confirms that the cage clamp is closed. Should the conductor need to be removed, the clamp can be opened using the tip of a screwdriver. Watch the videos on this page to see how it works.
Harting's HAN ES Press is also the first product in the HAN E product family that enables bridging of individual contacts for potential multiplication - similar to the way in which jumpers are used in terminal blocks. Various longitudinal and transverse bridges are available, which, for example, also enable star and delta circuits to be used for motor control.
Measurement points are accessible even after jumpers have been installed, making it easy to check for correct wiring and also for troubleshooting.
With a current capacity of 16A, the HAN ES Press is available in models 6, 10, 16 and 24 for housing sizes Han 6 B, 10 B 16 B and 24 B. The contact inserts are mating-compatible with the corresponding inserts in the HAN E, ES and ESS series. The cage clamps are suitable for wire cross-sections between 0.14mm2 and 2.5mm2 and can be used with both solid and stranded wires (with or without ferrules) for secure, vibration-proof connections.
