Harting is adding a new power transmission module to its Han-Modular industrial connector system. Known as the Han CD module, it is suitable for use with three-phase motors and servomotors.

This latest module incorporates three Han C power contacts (rated at 40A each) and four Han D signal contacts (rated at 10A each), all with crimp termination. It can be used for power transmission on three-phase motors where additional signal contacts are required – for a brake or for temperature measurement, for example. It has a high working voltage of 830V, making it also suitable for servomotor applications.

Finger-protected male and female contacts enable safe connections to be made in applications where the power could come from the male or female side – in frequency converters, power ring circuits or battery charging circuits, for example.

The Harting Han-Modular range is a highly flexible, diverse connector system that allows users to assemble connectors to their own requirements.

It includes a wide range of modules for electrical, optical, power and compressed air transmission.

Meanwhile, Harting’s Han-Quick Lock is an innovative termination technology for industrial interconnection that combines reliability and ease of assembly for applications involving high contact densities.

The concept combines the space-saving benefits of crimp technology with simple and rapid assembly, providing a rugged, vibration-resistant termination without the need for special tooling. This approach to assembly means that it can be quickly and safely disconnected and reconnected for maintenance purposes or as customers' requirements change.

Han-Quick Lock is based on a radial cage-clamp termination technique, and features a round spring that encloses the conductor strands and achieves high contact packing densities thanks to the radially symmetrical spring terminal.

The mating surface forms a specially shaped mandrel, and the necessary contact pressure is created on a surrounding edge. The connection is opened by means of an actuator, whereupon the conductor can be inserted without the application of force – which ensures that thin strands can also be introduced into the connection without becoming distorted.

Pressing the actuator fixes the conductor into position. Since the actuator closes flush with the connector, it is possible to perform a visual check to ensure that all connections are fixed. The conductor is released by retracting the actuator, then the conductor can be easily removed from the connection. The same conductor can be connected a number of times.

Harting’s first product to be equipped with the new termination technology is the Han Pushpull Power 4/0 connector. Further products, including Han 4 A and Han Q 5/0, will follow in the near future.
