Memory Stick Connectors CB1 Series is a type of connector for connecting Memory Stick from Japanese connector manufacturer JST. There are three types: card push insert, card push insert and eject, and no eject.
This handbook describes the HRS CB1 Series of Memory Stick® receptacle connectors, covering variants such as miniature, low‑profile, and those with or without an ejection mechanism. It outlines key features like incorrect‑insertion indication, contact protection, and ejection mechanisms.
Technical data include insulation resistance, voltage and temperature ratings, vibration and humidity performance, as well as recommended soldering profiles and packaging specifications. Handling precautions and mounting patterns are also provided to ensure reliable installation.
