The right-angle orientation puts the mating face parallel to the board — useful for cable exits along the board edge where z-height is tight. The 4-wall shrouding protects the male pins from bending during handling, and the locking ramp on the header engages the matching receptacle's latch for a vibration-resistant mate. ## Current rating and contact plating The current rating is listed as varies by wire gauge — the Micro MATE-N-LOK contact interface is rated for up to 5 A per circuit with 20 AWG wire in a single-wire seal configuration, but the actual limit depends on the wire size and the number of circuits powered simultaneously. Tin is cost-effective for moderate mating cycles (50–100 mates) and works well in dry indoor environments; for higher cycle life or corrosive atmospheres, the gold-plated variants in the same series are a better fit. This header mates with Micro MATE-N-LOK receptacle housings (crimp-socket terminals) — the locking ramp on the header and the latch on the receptacle click together and hold under vibration. The 3.00mm pitch and dual-row layout match the standard Micro MATE-N-LOK wire-to-board interface. Typical applications are general-purpose wire-to-board interconnects inside equipment enclosures — power supplies, control panels, industrial automation, and consumer appliances where the UL94 V-0 nylon housing meets the enclosure flammability requirement.","metaTitle":"4-794677-8 TE Micro MATE-N-LOK 18-Pin Right-Angle Header","metaDescription":"4-794677-8 TE Connectivity AMP Connectors Micro MATE-N-LOK header, 18 positions, 3.00mm pitch, through-hole right-angle, shrouded, board lock, tin contacts.","metaKeywords":null},"attributes":{"series":"Micro MATE-N-LOK","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"Micro MATE-N-LOK","Package":"Tray","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Locking Ramp","Number of Rows":"2","Pitch - Mating":"0.118\\\" (3.00mm)","Product Status":"Active","Voltage Rating":"250V","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.290\\\" (7.37mm)","Ingress Protection":"-","Base Product Number":"794677","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"18","Row Spacing - Mating":"0.118\\\" (3.00mm)","Contact Finish - Post":"Tin","Contact Length - Post":"-","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-40°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Tin","Contact Length - Mating":"-","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0300","priceTiers":[{"qty":1,"price":"$4.03000","currency":"USD"},{"qty":10,"price":"$3.58800","currency":"USD"},{"qty":117,"price":"$3.18564","currency":"USD"},{"qty":468,"price":"$3.16733","currency":"USD"},{"qty":1053,"price":"$2.61808","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/4-794677-8/alternatives.json"},"ai":{"faq":[{"question":"What is the mating connector for 4-794677-8?","answer":"It mates with Micro MATE-N-LOK receptacle housings that accept crimp-socket terminals.
