Cube relays

The  cube relay remains popular due to its robust construction and simple design; long with its interchangeability, it offers an excellent price to performance ratio in the range of 6 to 16 Amp PCB relay.

Hongfa has invested heavily in the manufacture of the Cube relay which is in contrast to other manufacturers some of which have reduced capacity whilst others have withdrawn from manufacturing this style of relay completely. Today Hongfa produces more Cube relays than ever and is by far the largest manufacture of cube relays producing more than 300 million annually.

Applications for the cube relay are many, but the white goods industry is still one of the largest with other applications including electric and hybrid vehicles for on-board charging, in the health sector, electrical bed control, HVAC for use in thermostats, robotics, remote RF control and also in uninterruptible power supplies. Over the many years in which the cube relay has been manufactured it is technically almost unchanged and has become established as a go to relay in numerous industrial applications.

Hongfa’s portfolio of Cube relays includes 12 variants from the popular HF3FA and HF3FF rated at 10 Amp for general switching control; the popular HF7FF and HF7FD rated at 12A for a higher performance, to the HF152F offering a 16 Amp Change Over contact arrangement. Other features available are class F Coils, fully sealed construction, Normally open and Normally Closed versions and IEC 60335-1 (Glow Wire Test) compliant versions for use in domestic appliances.

The cube relay is and remains one of Hongfa’s core products and they continue to invest in this technology. Further development of the Hongfa’s range include the HF3F-L relay, which represents a logical next step in the Cube Relays development. It has a bi-stable latching coil which only need a 10mS pule to change its state. Requiring no permanent power to the coil, it reduces power consumption, giving an energy saving over a standard cube relay.

As with all Hongfa products, their Cube Relay range carries approvals from internationally recognised approval bodies including cULus, CQC, TUV & VDE.
As with all products from distributor Switchtec, the company’s experienced, technically qualified field sales staff are available to discuss specific needs and to provide further information and support. Many versions of the Hongfa cube relay range are available Ex-stock from Switchtec.
