1.25mm & 1.5mm Signal GRACE INERTIA Connectors

TE Connectivity's (TE) 1.25mm and 1.5mm Signal GRACE INERTIA Connectors are designed for wire-to-board applications and feature surface-mount technology (SMT). An inertia-locking mechanism locks the connector into place when the circuit is completed, improving mating reliability and reducing the need for complicated inspections. The 1.25mm connectors have a single-row version that meets glow wire testing standards, and the 1.25mm pitch is offered in two configurations: wire-to-board and wire-to-wire. The signal 1.5mm connectors combine a space-saving design with durability and performance. TE 1.25mm and 1.5mm Signal GRACE INERTIA Connectors are suitable for power and signal applications, such as appliances, transportation, and lighting.
