PTSM/PTPM Terminal Blocks
World's smallest, rugged spring-cage connectors

High current throughput at 6 amps and a small centerline of 2.5 mm make the Phoenix Contact PTSM a truly unique and incredibly small spring-cage PCB terminal block. PTSM is available in the time- and cost-saving true surface-mount technology (SMT), as well as pin-in-paste when mounting components to the board. Phoenix Contact offers a pluggable PTSM version with push-in termination and a pluggable PTPM version with IPC termination for SMD and THR applications. The world’s smallest, rugged spring-cage connector, the PTSM stands at a minimal 5 mm tall. Termination can be as simple as pushing in a solid wire. Where space is critical, the PTSM is optimal.

Features and Benefits
 Technical Data Markets and Applications
  • Push-in technology enables easy and quick termination of conductors
  • Cost-saving solution for SMT processes
  • Rugged surface-mount device (SMD) anchors enable multiple plugging and disconnecting cycles
  • Small pitch (2.5 mm) and flat design (5 mm height) allow for endless design possibilities
PTSM
  • Horizontal and vertical headers enable flexibility in designs with multiple connection directions
  • Robust SMD anchors hold the PTSM firmly against the board
PTPM
  • Insulation piercing contact saves up to 80% of connection time
  • Tool-less termination
  • Transmits CAT5, provides greater options for data applications
  • Centerline: 2.5 mm
  • Conductor cross-section: solid/stranded up to 0.75mm2
  • Current rating: 6.0 A (UL pending)
  • Voltage up to 160 V
  • Spring-cage termination
  • True surface-mount technology or pin-in-paste
  • Lighting
  • Security and alarm
  • Building automation
  • I/O components in industrial networks
  • LED lighting
