Employing a pin-in-hole intrusive reflow method, the GT32 Series high-speed connector improves PCB retention force and enables a one-time reflow process with other SMT components. The connector, from Hirose, combines the reflow method with a positive locking structure that prevents partial locking, incomplete engagement and accidental disengagement. These features enable the connector to satisfiy demanding automotive specifications.

Offering enhanced EMI shielding and low near-end crosstalk (NEXT), the connector features a 1.5mm pitch and supports LVDS, USB3.0 and HDMI 1.4a Type E. Several versions are available, including a 4-position model with transmission speeds up to 3Gbps/pair, a 10-position version with transmission speeds up to 5Gbps/pair, and a 19-position model with transmission speeds up to 2Gbps/pair.

Well suited to harsh environments, the connector is resistant to vibration, physical and thermal shock (1000 cycles from -40°C to +85°C), sulfur dioxide and heat up to 105°C. A 98N lock strength is deployed by a positive lock mechanism featuring a clear audible tactile click when mated. The lock guard prevents lock deformation and cable snaring during delivery and assembly, but does not interfere with unlocking operation. Ensuring reliable connectivity, the GT32 utilises a 2-point contact form structure on the crimp contact with cost effective tin-plating.

Customisable, the connector is suited to automotive, railway, FA camera, servo amp, medical equipment, PPC and MFP applications. RoHS and ELV compliant, the connector has an operating temperature range of -40°C to +105°C and a rated voltage of 30V AC. Additional features include a rated current of 1 Amp, contact resistance of 30mΩ maximum (shielded), and insulation resistance of 100M ohms minimum at 500V DC.
