High-Temp Power Triple Lock Receptacle Housing
The TE Connectivity 6-1971775-3 is a 6-circuit receptacle housing from the Power Triple Lock, High Temp series. It is the panel-mount, fixed side of a wire-to-wire or wire-to-panel power interconnect system, designed for environments where the standard Power Triple Lock housing's temperature ceiling is insufficient. The defining spec here is the -55°C to 150°C operating range — that 150°C upper limit is the reason this 'High Temp' variant exists, and it's what you're paying for over the standard nylon housing.
6.00 mm Pitch, Panel-Mount Fit
The 0.236" (6.00 mm) pitch and 0.319" (8.10 mm) row spacing place this in the power-class range of the Power Triple Lock family — wide enough to handle the creepage for higher-voltage applications without forcing an oversized panel cutout. The panel mount, snap-in installation means the housing locks into a rectangular panel opening without additional hardware, which simplifies field replacement or assembly-line installation compared to a free-hanging housing that relies solely on the mating connector for strain relief. The choice between them comes down to whether the application needs the 150°C rating and a panel-anchored receptacle, or if the standard 5.08 mm pitch and free-hanging mount at a lower temperature rating is sufficient.
