Overview

The Phoenix Contact 1778845 is a 3-position, 2.5mm pitch pluggable terminal block designed for high-density wire-to-board connections. It features a tool-free push-in spring connection that accommodates wire gauges from 24 AWG to 20 AWG, providing a reliable and vibration-resistant termination in a compact form factor. This female connector is rated for 6A and 160V, making it suitable for low-profile signal and power distribution in space-constrained embedded systems.

Why Choose This Part

The push-in spring technology significantly reduces installation time by allowing direct wire insertion without tools while maintaining a constant force on the contact point for long-term reliability. Its 2.5mm pitch and 5mm height enable extremely high connection density compared to standard 3.5mm or 5.08mm terminal blocks.

Applications

Compact Industrial Sensor Hubs
Connecting multi-conductor sensor cables to miniature PCBs where vertical space is limited.
LED Lighting Control
Used in architectural or commercial lighting controllers for fast, secure wiring of low-voltage DC power.
Smart Home Actuators
Providing power and signal interfaces for small motorized blinds, locks, or HVAC dampers.
PLC I/O Expansion
High-density wiring interface for modular automation equipment requiring frequent disconnection for maintenance.
