HRS GT32-19DP-0.75CA

Product Overview

The HIROSE GT32 Series is a compact, shielded 4-position connector designed for differential signals. It features the industry's smallest shielded 4-position connector, with a width of only 8.25mm, making it ideal for space-constrained applications. The enhanced shield design in the GT32J variant shortens the GND path to reduce noise, making it compatible with LVDS protocols for video signals. The series offers multi-port receptacles and high-density mounting options, contributing to reduced manufacturing time. The GT32 is recommended for USB 2.0 connections, while the GT32J is suited for LVDS connections in applications such as automotive USB ports, various displays, IVI (In-Vehicle Infotainment), and automotive camera systems. This series is also applicable to non-automotive applications.

Usage Precautions

• Excessive pull force during unmating may damage the connector. If difficult to remove, push in lightly once and then release the lock.
• Always turn off power before reinserting the connector.
• Do not directly touch the terminal when electricity is flowing.
• Contact a Hirose representative for cable assembly procedures or handling manuals.

Notes

• Note 1: Includes the temperature rise due to current flow.
• Note 2: Storage refers to long-term storage for unused items before mounting the board. The operating temperature is applied when the circuit board is not energized after mounting, or when it is temporarily stored during transportation.
