Data sheet Weidmller Interface GmbH & Co. KG B2L 3.50/28/180F SN BK BX Klingenbergstrae 26 D-32758 Detmold Germany www.weidmueller.com Product image Component density redefined: the future standard Each reduction in size decreases space requirements and for signal connection so reduces overall system costs for the end customer. A maximum number of connections requiring minimum Thus, Weidmller fulfils a growing demand in the space - the double-row B2L sets the bar for field engineering and industrial automation sectors. connections of typical sensor cables up to 1mm very high and closes the gap betweenless spac andmore function. 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 Weidmller 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 General ordering data soldering, fast connection User-friendly - patented release lever for the easy release Version PCB plug-in connector, female plug, 3.50 mm, Number of poles: 28, 180, Tension-clamp of larger numbers of poles connection, Clamping range, max. : 1 mm, Box Application-oriented: easy labelling and reliable coding Order No. 1748280000 despite compact dimensions Type B2L 3.50/28/180F SN BK BX Miniaturisation is more than just a larger number of GTIN (EAN) 4032248156535 Qty. 30 pc(s). functions within a smaller space: Product data IEC: 250 V / 10.3 A / 0.2 - 1 mm UL: 300 V / 10 A / AWG 28 - AWG 16 Packaging Box Creation date January 27, 2022 4:06:32 PM CET Catalogue status 14.01.2022 / We reserve the right to make technical changes. 1Data sheet Weidmller Interface GmbH & Co.
