Phoenix Contact 1777811 PCB Connector

The PHOENIX CONTACT FRONT-MSTB 2,5/ 3-STF-5,08 is a versatile PCB connector designed for a wide range of industrial applications. Its front screw connection ensures a secure and reliable connection, while the 5.08mm pitch allows for efficient space utilization. Optimized for tight installation environments, this connector simplifies operation and conductor connection from a single direction. The screwable flange provides superior mechanical stability, and the low temperature rise, thanks to maximum contact force, contributes to long-term reliability. It supports connections for two conductors and is suitable for various conductor cross-sections, making it a flexible solution for diverse electronic projects.
