Honda Connectors / Honda Tsushin Kogyo (HTK) Industrial Connectors

Precision Interconnect Engineering by Honda Connectors and HTK

Honda Tsushin Kogyo Co., Ltd. (HTK / Honda Connectors) was established in Japan in 1932. Operating within the precision machinery group MinebeaMitsumi, the firm concentrates high-volume fabrication at the Azumino Factory in Japan alongside operations in Shenzhen.

Decades of tooling experience produce interconnects meeting rigid mechanical tolerances.

The engineering portfolio addresses factory automation, CNC machinery, robotics and automotive electronics.

High-accuracy stamping of contact pins, selective gold plating and 360-degree shielding ensure continuous signal throughput under electromagnetic noise and mechanical vibrations across modern production lines.

Half-Pitch Interface Connectors: PCR Series Architecture

The half-pitch PCR series with 1.27 mm contact pitch serves as an established standard for I/O module wiring, SCSI communication links and drive controllers. The product line provides cable plugs, straight board receptacles and right-angle headers ranging from 20 to 96 positions.

Fabricated metal shells deliver continuous electromagnetic protection.

Positive mating retention uses screw locks or snap latches to prevent disengagement under shop-floor vibration. Gold-plated contact fingers maintain low interface resistance and withstand atmospheric oxidation. The series connects ribbon cables and discrete twisted-pair sensor lines.

Heavy-Duty Industrial Ethernet: TAK 8 Vibration-Proof Interfaces

The eight-position TAK 8 series was designed by HTK engineers as a rugged industrial Ethernet alternative to standard RJ45 modular jacks. Standard plastic latch clips often fracture under continuous vibration, causing signal drops.

TAK connectors incorporate an automotive-grade latch mechanism that keeps plugs mated during heavy mechanical movement.

The plug and receptacle design provides 360-degree circular shielding against electromagnetic noise, isolating data lines from high-frequency inverter interference. Mechanical polarization keying and color-coded insulators prevent misconnection during regular maintenance on automated machinery.

Ultra-Dense Board-to-Board Connections: HDR and HDRA Series

Ultra-dense HDR and HDRA series interconnects feature a fine 0.8 mm pitch tailored for space-constrained controllers, machine vision systems and acquisition electronics. With refined pin profiles, these parts transfer high-speed digital signals with minimal crosstalk and low attenuation.

High-temperature thermoplastic housings withstand reflow soldering temperatures on automated surface-mount assembly lines.

Metal ground tabs connect directly to the equipment chassis, forming a closed barrier that protects delicate analog and digital circuits from static discharges and radio emissions.

Wiring Systems for CNC Machine Tool Servos and Resolvers

The positioning accuracy of machining centers and robotic units depends upon reliable feedback signal wiring. Honda Connectors assemblies link servomotor encoders, resolvers and motor power cables.

Heavy-duty sealing grommets and strain relief hoods shield terminals against oil mist, lubrication fluid and coolant splashing.

Precise dimensional fit enables drop-in servicing of cable terminations without modifying cabinet panels. Terminals endure repeated mating cycles while maintaining stable resistance despite fluctuating thermal conditions and ongoing mechanical shock.

Technical Selection and Specification of Connectors and Harnesses

Selecting the correct Honda Connectors / HTK component requires verifying the series designation, pin count, mounting orientation and hood locking style. Inquiries should include the factory part marking, machine documentation reference or clear photographs of the mating port.

For custom cable harnesses, engineers specify overall length, protective jacket material suitable for drag-chain flexing, and pinout diagrams. Technical specialists check terminal compatibility and provide quotations with delivery timelines for your plant.
