Available from specialist distributor Switchtec, the 2009 Hongfa relay catalogues showcase the complete range of relays from this high quality manufacturer. Literally packed with information, the catalogues are a great help for designers, specifiers and buyers who need to quickly and easily access information about any relay in the vast Hongfa range.

The A4, full colour catalogues are very useful to people working in a wide range of industries and sectors including PCB manufacturers and suppliers, distributors, wholesalers, OEMs, manufacturers, panel builders, and the automotive and aerospace industries.

The five catalogues each cover a specific range of Hongfa relay products namely, general purpose, solid state, automotive, hermetically sealed and relay sockets.

The 376 page general purpose relay catalogue includes the sub-miniature 1A, HF23 relay up to the large 200A HFE6 latching relays. New to the 09 catalogue are the HF115FP with its built in LED and test button, the HF13F now being available in a 3-pole version, the plug-in HF157F relay and the HFE12, 120A latching relay.

The solid state relay catalogue Includes the miniature HFS2 MOS relay up to the large 3 Phase HFS24 SSR and is 88 pages long. New to the 09 catalogue are the HFS32 plug in SSRs and the HFS28 dual AC output relay, together with all of Hongfa’s SSR accessories.

The automotive relay catalogue is 122 pages long and includes PCB and plug in relays, from the popular HFV4 30/40A plug in relay to the miniature twin relay HFKD with two relays in one housing. New to the 09 catalogue are the HFV9, with its extended temperature range of 125degC and the automotive relay modules, available as flasher control, wiper control and delay relays.

The 134 page hermetically sealed relay catalogue includes Hongfa’s TO-5 and half crystal can hermetically sealed relays. New to the 09 catalogue is the Hongfa cube, half cube, 2/5 cube and 1/5 cube relays.
The relay sockets catalogue includes the 6mm wide 41F series socket and the popular 8, 11 and 14 pin plug in relay sockets. New for the 2009 catalogue is the inclusion of the 118F PCB socket for the HF118 power relay. This catalogue is 70 pages long.

Simple to use, the catalogue has a photo of each relay listed. It also shows each relay’s dimensional layout and its footprint. Full technical information is provided including ratings, configuration, voltage, pitch options, and other technical details.

An easy to use selection guide is positioned at the front of each catalogue. Each product listing also has a typical application section that shows suggested applications for each style of relay.

Automotive relay range is vast for wide range of applications

Specialist distributor Switchtec is offering a range of automotive relays from Hongfa. New cars are using more and more relays to control attractive, ‘value added’ features and functions within the vehicle. This has led to an increase in demand for automotive relays year on year. The total automotive relay output for China for 2007 was 137 million relays, up 15% on 2006. Demand is forecast to increase to 650 million relays by 2010.

Aimed at the automotive Industry, OEMs, equipment manufacturers, and PCB manufacturers/builders, the relays are used in automobiles, mobility vehicles, waste collection vehicles, caravans and trailers, and in motor control applications such as lifts, robotics, and garden machinery.

Ratings wise, the Hongfa automotive relay series ranges from the small PCB relay HFKW rated at 15A up to the large 70A HFV7 panel mount relay.

A technological development achieved by Hongfa is the twin relay. Two relays are packaged in one housing, both with their own coils and contacts. This space saving development enables more relays to be fitted to a PCB, as the relays can be populated closer together, saving valuable PCB space and reducing enclosure sizes and weight, which is a serious consideration in many automotive applications. Hongfa currently has three types of the relay that are also available as a twin relay. These are the HFKA, HFKC and the HFKD.

The latest automotive relay from Hongfa is the HFV9. This is a miniature relay measuring just 25x22x15mm, yet capable of switching 20A. Suitable for PCB or Faston connections, the relay’s compact size and high performance is ideal for automotive applications.

To perform some of the more complex applications within a vehicle, application specific relays are required. These are the Hongfa HF350 relays for flashing control (indicators), wiper control and delaying relay (oil pump).

All of the Hongfa automotive relays from Switchtec are RoHS and ELV compliant. With over 40 automotive relays types, and an ever-expanding production capacity, Hongfa offers a complete automotive relay series. Major customers of Hongfa include Ford, Fiat, Delphi, Chery, and Jiangling motor companies.

With a 700 million piece manufacturing capacity, Hongfa is the largest relay manufacturer in China. Appreciating the importance of the automotive industry worldwide, Hongfa was the first relay manufacturer to achieve the automotive standard TS16949.

Hongfa has a design and production facility dedicated to automotive relays. It is equipped with the latest moulding, assembly and production technologies. Hongfa also has its own internal test house, which is recognised by TUV, VDE, UL and CNAS, enabling Hongfa to complete in house testing to higher standards, shortening approval lead times and allowing for increased production flexibility.

The Hongfa automotive relay range is available from Switchtec on short delivery times. A dedicated automotive relay brochure is also available.
