Phoenix Contact 1704857 4 Position Plug Connector

The Phoenix Contact 1704857 plug connector is a miniature component ideal for applications requiring a compact and reliable connection. Designed with a 2.5mm pitch, it's compatible with both THR (Through-Hole Reflow) and SMD (Surface Mount Device) base strips, providing versatility in assembly. The push-in spring connection ensures easy and secure termination of conductors, while the white housing and tin-plated contacts contribute to durability and corrosion resistance. This connector is commonly used in industrial automation, control systems, and power distribution panels where space is limited and reliable connections are essential.
