Right-angle header for board-to-wire connections with locking retention
The 3-794620-6 is a Micro MATE-N-LOK header from TE Connectivity AMP Connectors, designed for board-to-cable/wire applications. It carries 6 circuits in a dual-row arrangement on a 3.00 mm pitch, with a matching row spacing of 3.00 mm. The right-angle through-hole orientation lets the mated cable exit parallel to the PCB, which suits low-profile enclosures and board-edge routing. The shrouded four-wall design protects the male pins during handling and guides the mating receptacle into alignment.
Locking ramp and board locks for vibration resistance
A locking ramp on the header engages with the mating receptacle's latch, providing audible and tactile feedback that the pair is fully mated and resistant to vibration-induced disconnection. Integrated board locks anchor the header to the PCB during wave soldering and resist shear forces from cable strain, which is a practical concern in equipment that sees field handling or transport vibration.
Gold-plated contacts and wide temperature range for reliable signal duty
Mating contacts are plated with 30.0 µin (0.76 µm) gold, which resists corrosion and maintains stable contact resistance through repeated mating cycles. The post finish is 100.0 µin (2.54 µm) tin, compatible with standard lead-free soldering processes. The header is rated for an operating temperature range of -40°C to 105°C, covering most indoor industrial and automotive interior environments. The nylon housing carries a UL94 V-0 flammability rating, meeting the flame-retardant requirement for equipment inside enclosures.
Current rating depends on wire gauge and contact selection
The current rating is listed as varies by wire gauge, meaning the actual ampacity is set by the mating crimp contact and the wire size used in the harness. For a given application, the limiting factor is the temperature rise through the contact interface, not the header itself.
