Combined with the latch holder, the connection resists vibration-induced disengagement — useful in equipment that sees periodic shock or where the cable is routed near moving parts. ## Glow wire compliance and flammability rating — why they matter The V-0 rating means the material stops burning within 10 seconds after a flame is removed, with no flaming drips — a requirement for appliances, lighting fixtures, and industrial controls where the connector is inside an enclosure that must meet IEC/EN 60335 or similar standards. The 250VAC voltage rating and -40°C to 120°C operating temperature range align with typical appliance and general-purpose equipment environments. The temperature ceiling of 120°C is the housing material limit, not the contact interface — derate current above 85°C ambient per the manufacturer's curve.","metaTitle":"7-1971845-7 TE Connectivity Header, 5.00mm Pitch, 7 Pos","metaDescription":"7-1971845-7 TE Connectivity AMP Connectors header, 5.00mm pitch, 7 positions, shrouded 4-wall, latch holder, glow wire compliant, UL94 V-0.
