1971777-5 is a locking plate component designed for the TE Connectivity POWER TRIPLE LOCK connector system. It is compatible with standard temperature, high temperature, and glow wire connector variants, providing enhanced mechanical security through the triple-lock design philosophy. The locking plate features a 1 x 5 position configuration with 6.0 mm centerline pitch and is rated for continuous operation up to 150°C, supporting both wire-to-panel and wire-to-wire connection applications. The black thermoplastic housing meets glow wire test requirements per IEC 60335-1, ensuring compliance with appliance safety standards. This component works in conjunction with connector position assurance (CPA) and terminal position assurance (TPA) devices to deliver three independent locking mechanisms, making it ideal for demanding power and signal applications in home appliances and industrial equipment where reliable connections are critical.
