Maximum Device Design Flexibility

Always find the right connection – with WAGO’s THT female headers from the MCS MAXI 6 PCB Connection System.

Wire-to-board (W-to-B), board-to-board (B-to-B), board-to-wire (B-to-W) or wire-to-wire (W-to-W)? No matter what type of connection solution your power electronics application needs, WAGO’s MCS MAXI 6 PCB Connection System has the solution with new THT female headers. This system allows more design freedom for users such as drive and control technology developers.

WAGO’s MCS MAXI 6 Connection System enables high current carrying capacities of up to 57 A and, with the new THT female headers, offers even greater flexibility for designing power electronics connections. Now it is possible to combine a THT female header with a THT male header to connect two boards (B-to-B) easily and flexibly. The touch-proof THT female header, combined with a 1-conductor male header (B-to-W), maximizes safety for PCB power outputs. At the same time, the power inputs and outputs are readily identifiable both visually and functionally. Furthermore, WAGO’s MCS MAXI 6 Connectors are 100 percent protected against mismating and can be printed and coded to meet customer requirements.

The THT female headers are available as 2- to 9-pole straight or angled models in 7.62 mm pin spacing. They have three solder pins per pole, providing a highly stable mechanical and electrical connection to the PCB. The test opening is easily accessible at a 90-degree angle to the mating direction.

The Benefits for You:

  • Several connection options provide superior design flexibility
  • Connect two PCBs (board-to-board) with a high current carrying capacity of up to 57 A
  • Solderable female header for a touch-proof PCB output (board-to-wire)
