WAGO 805-103 3-Pole PCB Terminal Block

The WAGO 805-103 is a compact 3-pole PCB terminal block designed for reliable and maintenance-free wire-to-board connections in industrial automation and electronic control equipment. Belonging to the WAGO 805 Series, this modular terminal strip incorporates push-button actuation alongside push-in spring connection technology, enabling fast, tool-free conductor wiring for both solid and ferruled stranded conductors. Operators can easily open the clamping spring using a simple screwdriver or finger press to insert or release fine-stranded wires, ensuring secure vibration-proof contact under demanding industrial conditions. Engineered for printed circuit board mounting, the WAGO 805-103 provides a standard 3.5 mm pin spacing and is suitable for discrete signal and low-voltage power distribution across programmable logic controllers, I/O modules, power supplies, interface relays, and instrumentation devices. The robust insulating housing delivers dependable electrical isolation and thermal endurance within switch cabinets and embedded machinery controls. Its low-profile architecture conserves valuable board space while supporting streamlined assembly and field maintenance in modern automation systems.
