  • Front screw connection for narrow device fronts and PCB racks
  • Push-in spring connection with push button for fast and tool-free conductor connection
  • Push-Lock spring connection for tool-free connection of rigid and flexible conductors with and without ferrules
  • Push-in spring connection with screwdriver actuation for fast and tool-free conductor connection
  • Spring-cage connection for easy connection without the need for special tools or conductor preparation
  • IDC insulation displacement connection as a particularly time-saving connection technology

Mounting types, connection technologies, and convenience functions

Printed-circuit board terminal blocks, also called PCB terminal blocks, are mounted on boards in a variety of methods. These methods include wave soldering, THR soldering (Through Hole Reflow), and SMT soldering (Surface Mount Technology).

A wide range of connection technologies, such as screw connection, connection via Push-in or Push-Lock, spring-cage connection, and IDC insulation displacement connection allow perfect integration into your application.

Convenience functions provide a high degree of user-friendliness when connecting and maintaining the PCB terminal blocks. These include optimal integration into the front of the housing thanks to uniform design, maximum clamping space even with the smallest dimensions, components for SMT and THR processes in automated and standardized packaging, and printing, marking, and color coding for simple installation.

Accessories and convenient functions for maximum versatility

Numerous convenient functions provide a high degree of user-friendliness when connecting and maintaining the PCB terminal blocks. These include:

  • Individual markings for easier installation and reduced risk of wiring errors
  • Compact design for high levels of connection convenience and numerous possible applications – even if space is limited or the design is restrictive
  • Integration into the device front thanks to the uniform design and flush housing terminations
  • Solutions for SMT and THR for automated assembly processes, supplied to you in automated and standardized packaging.
  • Multi-level versions for space-saving conductor connection (for wave and THR soldering processes)
  • Safe mounting flange
    for easy attachment and release, and to take the strain off the solder pins
  • Multi-row arrangement for a particularly high connection density on the PCB
  • Easy potential distribution with fixed or plug-in bridges
  • Integrated test points for measurements, without removing the wiring or other accessories
