Utilizing METZ CONNECT Springcon technology for secure, vibration-resistant connection that automatically adjusts to 28–16 AWG wires, SC305 and SL305 series facilitate wire-to-board connection without header. Contact is established directly on solder pads, allowing opposing side of PCB to be used for components. With 5 mm centerline, solid wires insert directly for tool-less connection. While SL305 is direct solder component, SC305 is snap-fit version for traditional wall-plate applications.
