Terminal Block for Panel Wiring — 4 Positions, 3.5mm Pitch
The 1-2834019-4: It is designed for wire-to-board termination in industrial control panels, building automation, and power distribution — anywhere a reliable, tool-free wire connection is needed on a PCB. Rated 6 A per position at 300 V. The screwless clamp accepts 16-20 AWG solid or stranded wire.
Screwless Termination — What It Means on the Line
The screwless wire termination is a spring-clamp or push-in mechanism — no screw to torque, no risk of over-tightening or backing out under vibration. Insert the stripped wire into the clamp opening; the spring applies constant pressure on the conductor. For 16-20 AWG, the contact force is set at the factory; the tin-plated copper alloy contact resists corrosion in indoor panel environments. On a high-volume build, this shaves seconds per termination and eliminates the torque-check step. The single level keeps all four terminations on one row, so wire routing is straightforward and each clamp is accessible without reaching over adjacent terminations.
