DAS Company is an authorized Hongfa Europe GmbH distribution partner, stocking and supplying the complete Hongfa relay portfolio — HF115F and HF152F miniature high-power PCB relays, HF46 and HF14FF compact PCB relays, HVDC high-voltage DC relays for EV and energy storage, latching bistable relays, HFD2/HFD4 signal relays and HF116F industrial DIN-rail socket relays — to OEM electronics manufacturers, panel builders and automation engineers across Europe from our Bulgaria distribution base.
Hongfa Technology Co., Ltd., headquartered in Xiamen, China, is the world's largest relay manufacturer by unit volume — holding the leading global market share in power relays, automotive relays, HVDC relays, latching relays and signal relays. Founded in 1990, Hongfa has grown to serve customers in over 100 countries through manufacturing facilities in China and Hongfa Europe GmbH (Germany), which manages European distribution, application engineering and after-sales support for the European market. Hongfa products are distributed through Arrow Electronics, Rutronik, Mouser Electronics, RS Components and Farnell globally — confirming Hongfa's position as the standard specification for PCB relay applications across consumer electronics, industrial automation, HVAC, smart home and electric vehicle OEM programmes worldwide. Hongfa was selected for the 2025 "Top 50 Supply Chain" list for new energy and intelligent connected vehicles — reflecting the growing importance of its HVDC and automotive relay segments alongside the established PCB and industrial relay business.
The Hongfa HF115F (1-pole SPDT 1CO or SPNO 1NO, 16A AC1 / 250V AC, PCB mounting, 5.0 mm pin pitch) is one of the world's most widely installed appliance power relays — the standard specification for white goods (washing machine, dishwasher, oven), HVAC heat pump controller boards, smart home load switching and industrial equipment power control PCBs. The HF115F is manufactured using high CTI 250V grade plastic material — providing enhanced electrical tracking resistance and surface creepage performance that meets European appliance safety standards (IEC 60335 series) for global market product certification. Coil voltages available include 5V, 9V, 12V, 24V and 48V DC — the 12V DC version being the highest volume specification across automotive accessory and consumer electronics 12V system applications. The compact 28.7×12.8×15.7 mm body and 400 mW coil power consumption enable easy thermal management on space-constrained control PCBs. The sealed construction variant (suffix -S) provides IP67 protection against flux penetration during PCB wave soldering — eliminating the contact contamination failures that affect unsealed relays in solder-flux environments. The HF152F series (20A, 1CO) is the uprated variant for heating element and motor load applications requiring higher switching current than the HF115F 16A rating.
The Hongfa HF46 (1-pole SPDT, 10A / 250V AC, 19×15.5×15.2 mm) is the compact alternative to the HF115F where PCB footprint reduction is prioritised over maximum contact rating — widely specified in energy meters, smart plugs, charging controllers and compact industrial I/O modules. The HF46F variant (flux-sealed, PCB mount) and HF46F-G (with bifurcated gold contacts for low-level signal switching reliability) extend the HF46 base design for telecommunications and signal measurement applications where AgNi contact performance at low switching voltages is required alongside the convenience of a single relay covering both signal and power load duties. The Hongfa HF14FF (1-pole SPNO 1NO, 10A, PCB mount, DIN socket compatible) serves as both a PCB-mount and panel relay — available with the 14FF-1Z-C2 single-pole DIN socket for plug-in relay panel installation, bridging the PCB relay and panel relay product categories in a single product family.
Hongfa HVDC relays (High-Voltage DC contactors) are specifically designed for electric vehicle battery management, EV charging systems, solar energy storage and grid-scale battery applications where DC voltages from 450V to 1,500V and currents from 100A to 1,000A must be switched safely under DC fault conditions. Unlike standard AC relays that rely on zero-crossing arc extinction, Hongfa HVDC relays use sealed ceramic arc chamber construction with hydrogen or nitrogen arc-quenching gas fill — providing reliable arc extinction at the rated DC voltage for the specified number of load switching operations. Hongfa HVDC relays are certified to IEC 62196, UL 2231 and GB/T 24347 for EV charging applications, and are specified by leading EV manufacturers and charging station OEMs across China, Europe and North America. The selection for the 2025 "Top 50 Supply Chain" list for intelligent connected vehicles confirms Hongfa's position as a tier-1 HVDC relay supplier to the global automotive and energy storage industry.
Hongfa latching relays maintain their last-set contact position without coil power — consuming zero standby energy once switched, compared to continuous coil energisation required by standard monostable relays. This property makes latching relays the mandatory specification for smart electricity meter disconnect switches (where the meter must disconnect the load on command without continuous coil power consumption), load control relays in building energy management systems and battery-powered IoT devices where relay coil power would significantly reduce battery life. Hongfa latching relays are available in PCB-mount and DIN-rail socket formats with single-coil (pulse drive) and dual-coil (separate set/reset coil) operation, covering 5V, 12V and 24V DC drive voltages. Switching capacities range from 16A (single-pole smart meter disconnect) to 63A (main supply disconnect for large commercial smart metering applications).
The Hongfa HFD2 (DPDT 2CO, 0.6A / 125V AC, PCB, low power 0.20–0.30W coil) and HFD4 (SPDT 1CO, 3A / 125V AC, PCB) are precision signal relays for telecommunications switching, instrumentation and test equipment applications requiring high isolation between switched circuits, low contact resistance and reliable low-level signal switching (10mA to 1A). The bifurcated gold-clad AgPd contact material in HFD series relays provides consistent performance at switching levels below 100mV/1mA — where standard AgNi contacts exhibit unreliable intermittent contact behaviour due to insulating surface films. HFD relays are available in both PCB THT and SMT (surface mount reflow solder) formats for high-volume automated PCB assembly in telecommunications and industrial electronics OEM production.
The Hongfa HF116F provides the DIN-rail socket relay format for industrial panel applications — a 16A SPDT plug-in relay body with compatible DIN-rail sockets (screw and spring-clamp termination) for machine control, PLC output buffering and HVAC control panel relay logic. The HF116F offers direct substitution for standard industrial DIN relay formats (Finder Series 40, Schrack RT, Phoenix Contact REL) at reduced cost — providing Hongfa PCB relay quality and manufacturing scale benefits in the industrial panel socket relay format. The 14FF-1Z-C2 DIN socket compatible with HF14FF and HF115F relay bodies extends the HF product family to panel relay socket applications using the same relay bodies specified on control PCBs — reducing spare parts inventory by sharing relay body SKUs between PCB and panel relay applications.
