4-Position Receptacle Housing for 1.20 mm Pitch Micro Connectors
The Hirose DF57H-4S-1.2C(08) is a 4-position receptacle housing from the DF57H series, designed for fine-pitch wire-to-board interconnects at 1.20 mm pitch. The natural LCP housing carries a swing lock for positive retention in vibration-prone environments, with an operating range of -35°C to 85°C.
What the 1.20 mm Pitch and Swing Lock Mean for the Fit
The 1.20 mm pitch places this in the micro-connector class — the board footprint is compact, but the fine pitch limits current per circuit. Because the housing is free-hanging, it relies on the lock, not a board anchor, for strain relief.
This housing ships without crimp contacts. The crimp termination allows on-site re-pinning with a basic crimp tool, which is the main serviceability advantage over a pre-molded overmold assembly.
