  3.81mm Connectors

Weidmuller has extended its family of 3.81mm pitch connectors.  The 3.81mm connectors are designed to provide the maximum degree of freedom for the design of signal terminations on the printed circuit board.  They offer state-of-the-art design and performance with unique features such as increased current ratings, multiple applicability and flat dimensions.  The enhanced 3.81mm connector series complement Weidmuller’s well-established 3.5mm range and include the following enhancements:

  • Compatibility:  100% interchangeable to the industry standard with the most comprehensive range of products available
  • Performance:  Increase current carrying capacity when compared to the marked; up to 10A per contact (instead of 8A) without derating at ambient temperatures up to 65°C
  • Applicability:  Suitable for all applications, offering a high degree of design freedom for board-to-wire, wire-to-board, wire-to-wire and board-to-board interconnections
  • Safety:  High reserves due to higher temperature resistance and current carrying capability as well as maintenance-free, vibration resistant connection systems
  • Usability:  Automated production and tool less operation through patented solder flange, lock and release lever and Push-In connection
  • Efficiency:  Cut manufacturing costs through a broad range of SMT headers for reflow soldering and automated pick and place machines
