## **Component density redefined: the future standard for signal connection** 

A maximum number of connections requiring minimum space - the double-row B2L sets the bar for field connections of typical sensor cables up to 1mm² very high and closes the gap between "less space" and "more functions". 

The result is a connection solution for standard industrial cables in 1.75 pitch - 30% smaller than equivalent solutions in 2.5 pitch, and with the 140% robustness of the 3.5 pitch Dimensions: double the connection density with a 3.5mm pitch size Connection system: tried and tested maintenance-free Weidmüller tension clamp connection The basic application advantages: 

Efficient: maximum component density on the PCB Suitable for industrial use - minimum dimensions, maximum robustness Process-optimised - automatic assembly and reflow soldering, fast connection 

User-friendly - patented release lever for the easy release of larger numbers of poles Application-oriented: easy labelling and reliable coding despite compact dimensions Miniaturisation is more than just a larger number of functions within a smaller space: 

Each reduction in size decreases space requirements and so reduces overall system costs for the end customer. Thus, Weidmüller fulfils a growing demand in the engineering and industrial automation sectors.
