Each tin-plated brass contact is rated for 7.5 A at 250 VAC, with a friction lock that holds the mating housing securely against vibration and accidental disconnection. The through-hole solder termination and 1-wall shrouding simplify board layout and provide basic polarization for the mating connector. This header mates with standard 0.156 inch (3.96 mm) pitch crimp receptacle housings from the Economy Power series, such as the 1-480700-0 family. The friction lock requires the matching housing with a lock ramp. The overall contact length is 0.575 inch (14.60 mm), with a mating length of 0.303 inch (7.70 mm) and a post length of 0.145 inch (3.68 mm).","metaTitle":"1744057-3 TE Connectivity Economy Power Header, 3 Pos 3.96mm","metaDescription":"1744057-3 TE Connectivity AMP Economy Power series, 3-position 3.96mm pitch vertical header, 7.5A, 250VAC, friction lock, active production.
