Phoenix Contact Print Terminal Spring (PTS) Terminal Blocks

Introduction

Phoenix Contact Print Terminal Spring (PTS) terminal blocks are compact PCB connection components designed for reliable, efficient wire termination. Their push-in spring connection design supports quick installation without requiring tools, making them well suited to space-conscious electrical and electronic assemblies.

Part Description

The Phoenix Contact PTS terminal block series, including product codes 1751973, 1831879, and 1831880, provides a practical interface between printed circuit boards and field wiring.

These terminal blocks use a spring-cage push-in connection method, allowing compatible conductors to be inserted directly into the terminal. This helps simplify assembly and can reduce wiring time compared with screw-clamp terminals. Internal bridging supports convenient power distribution between terminal positions, reducing the need for additional external jumper wiring in suitable designs.

Key characteristics include:

• 5 mm terminal pitch for compact PCB layouts
• 400 V rating for higher-voltage control and distribution circuits
• Support for conductor cross-sections from 0.2 mm² to 2.5 mm²
• Tool-free push-in termination for simplified installation
• Internal bridging for streamlined power distribution
• PCB-mountable terminal block construction

Applications

Potential applications for Phoenix Contact PTS terminal blocks include:

• Building automation controllers
• HVAC control boards
• Lighting control systems
• Power distribution modules
• Alarm and security control panels
• PLC interface boards
• Motor control and actuator connection boards
• Smart building gateway devices
• Sensor and field-device wiring interfaces
• Industrial control panel electronics

Industries

These terminal blocks can be used in a range of industries, including:

• Building automation
