Each row is spaced at 0.165 inch (4.20 mm) — the same pitch as the row-to-row spacing, so the contact grid is square. That 4.20 mm pitch sets the board footprint and the per-contact current ceiling: at 6 A the temperature rise stays within the UL94 V-0 nylon housing rating. The 4-wall shrouding protects the male pins during handling and guides the mating receptacle into alignment. The latch lock on the shroud provides audible feedback on full engagement — useful in a harness assembly where the connector is blind-mated against a panel or bulkhead. ## Tin-plated contacts — moderate-cycle, cost-effective interconnect Tin-on-tin contacts are rated for a moderate number of mating cycles — typically 25 to 50 cycles before fretting corrosion becomes a concern. For a field-service application where the connector is cycled a few times a year, that is decades of service at the contact interface. The circular male pins are phosphor bronze, a standard spring alloy that resists stress relaxation at the 105 °C upper operating limit. ## Active production — sourced per BOM quantity No stock-holding claim; sourced through independent distribution per RFQ.","metaTitle":"640506-3 TE Connectivity AMP Connectors 36-Pin Header 4.2mm","metaDescription":"640506-3 TE Connectivity MR series 36-position header, 4.20mm pitch, 6A, 250VAC, tin-plated contacts, latch lock, UL94 V-0.
