The TE 1-827578-1 is a 3-position, single-row receptacle housing from the Junior Power Timer series. It uses a 5.00 mm pitch and is designed for free-hanging (in-line) wire-to-wire or wire-to-board harness applications where a compact, keyed interconnect is needed. The housing is molded in black glass-filled PA66, a material that handles the thermal and mechanical demands of automotive and industrial environments. Contacts are ordered separately — the housing accepts standard Junior Power Timer female crimp sockets, so the BOM line for this part is just the plastic shell; the terminals are a separate line item.
The 5.00 mm pitch and single-row layout keep the housing width compact for a 3-circuit harness.
