Huizhou Antenk Electronics Co., Ltd. (IATF16949, ISO9001, ISO14001 certified) presents the MX4.20mm 90° Wafer Connector Series. This wire to board connector features a 4.20mm pitch and right angle orientation, designed for medium to high power applications requiring secure locking and vibration resistance. The housing is molded from high temperature UL94 V-0 PBT or nylon 66, equipped with a positive locking ramp for audible mating confirmation. Contacts are stamped from phosphor bronze with selective tin or gold plating, rated up to 9A per circuit. Key specifications include contact resistance below 10 milliohms, insulation resistance above 1000 megohms, dielectric strength 1500V AC, and operating temperature from -40 to +105 degrees Celsius. The 90° design allows parallel PCB mounting with vertical cable exit, saving board space. RoHS and REACH compliant, UL recognized under E472792.
Applications include power supplies, battery chargers, LED lighting, industrial controls, home appliances, and automotive electronics. Usage method: solder the through hole pins to the PCB using wave soldering. Mate with a corresponding 4.20mm crimp style female housing; the lock engages with a click. Precautions: do not exceed 9A per circuit, ensure proper crimping of terminals, verify latch engagement. Advantages over competitors: Antenks MX4.20mm series features reinforced locking strength (≥5kgf retention) and terminal alignment guides to prevent stubbing during mating. Tight pin coplanarity within 0.08mm ensures reliable soldering. Low MOQs of 1000 units with no tooling fees.
Production process: in house mold design, injection molding on 10 Japanese and Taiwanese machines, high speed stamping of terminals on 9 presses, selective plating, automated pin insertion and right angle forming, 100 percent coplanarity and contact position inspection, contact resistance and insulation tests, 48 hour salt spray test, and final QC with lot traceability. Free samples, 2D and 3D CAD drawings, and 24 hour technical support available. Contact Antenk for custom circuit counts and plating.
