Terminal Blocks & Connectors

DIN-Rail Terminal Blocks

Molex DIN-Rail Terminal Blocks offer a modular and scalable system that uses 35mm DIN rails to maximize space and performance. These terminal blocks are available in two wire termination styles: screw and plug-in/push-in. Both types provide safe and reliable power connectivity for a broad range of industries and applications. Molex DIN-Rail Terminal Blocks feature a vibration-resistant design with robust clamping to help prevent failures in harsh environments. The product line helps streamline the integration of complex wiring layouts in applications such as industrial automation, energy, HVAC, agricultural machinery, automotive, telecommunications, and data centers.
