Description


  • PCB terminal strips with push-buttons and CAGE
    CLAMP® connection
  • Versions with Ex approval
  • Set to metric or inch pin spacing by compressing PCB terminal strips or
    pulling them apart
  • Ideal for in-the-field wiring thanks to simplified push-button actuation
  • Convenient, tool-free operation
  • Versions with angled push-buttons for simple top-of-unit actuation
