7pin High Density 10A Inserts

The HD-007-MC and HD-007-FC are compact 7-contact crimp inserts designed for 3A heavy-duty connector housings. The MC and FC versions form the male and female mating pair, with 7 contacts plus PE, making them suitable for compact power and signal connections.

The inserts use copper-alloy contacts, available with silver or gold plating, while the crimp termination makes wiring straightforward and convenient for assembly and maintenance. With a compact design and reliable contact performance, the HD-007 series works well in industrial automation, machinery, control equipment and other applications where installation space is limited.

As rail transit develops towards higher speeds and greater intelligence, the complexity of electrical connections in vehicle systems is also constantly increasing. From traction systems to control systems, and then to onboard communication and monitoring equipment, the various electrical connections are not only numerous but also have extremely high requirements for reliability and safety. Against this backdrop, modular heavy-duty connectors are gradually becoming an important solution for electrical connections in rail transit.

In injection molding, how precisely the hot runner temperature is controlled has a direct impact on the final product quality. The temperature controller, as the key unit in the system, relies on stable electrical connections with the various hot runner components. Heavy-duty connectors play an important role here—they act as a reliable interface within the temperature control system, helping ensure that both power and temperature signals are transmitted accurately and consistently, even in demanding working conditions.

Zhejiang Haoke Electric Co., Ltd. (ZJHK) focuses on the R&D and manufacturing of heavy-duty connectors. Since entering the industry, we have kept our attention on this field and gradually built a complete product range covering HA, HE, HEE, HEEE, HD, HDD, HSB, HK, HQ and HM series, with thousands of possible combinations.

Our team includes experienced technical staff, production personnel and quality specialists, allowing us to handle product development, customization and daily orders in-house. The company also has its own mold and production capabilities, with an annual capacity of around 1.5 million sets of heavy-duty connectors.
