120220-0314 is a Universal Contact Z series spring contact with a 3.5mm height, designed for reliable board-to-board electrical connections. Manufactured from Titanium Copper alloy, it features a protective box design with side wings that guide the beam within its operating stroke and maintain pre-load in the unmated condition. The contact incorporates a domed contact point for high hertz stress contact and good contact resistance, with gold over nickel plating on the contact position. Key electrical specifications include a maximum contact resistance of 20 mO, rated current of 1.50A, and peak current capability of 2.5A. The contact operates over a temperature range of -40°C to +85°C and is suitable for lead-free reflow soldering at 260°C, making it ideal for SMT assembly in consumer electronics, telecommunications, and industrial applications.
