Description

Double row terminal plug selection

15KN plugs provide two rows of spring connections with individual release buttons. Each row has 2–24 poles, giving 4–48 poles in total. Choose the exact pitch, housing profile and fixing arrangement; similar appearance does not establish mating compatibility.

3.5mm KNHB, KNHBM and KNHBG dimensions

The HB drawings use N for the total pole count across both rows, so N=2P. Their length expression 3.5(N/2−1)+3.90 therefore equals 3.5(P−1)+3.90.

Model	Core body length	Body height / mating projection	Depth	Retention and mating geometry
TB01-15KNHB/3.5	3.5(P−1)+3.90	18.50 reference / 7.80	15.00	End offset 1.95; mating row spacing 6.25 with 2.50 edge distance

The HB and HBM drawings also show the raised housing features for 4-, 6-, 8- and 10-pole configurations; use the illustrated pole configuration when checking the mating housing.

15KNHB 3.5mm double row push in plug dimensions — TB01-15KNHB/3.5 body and mating face; N is the total pole count.

15KNHBM 3.5mm fixing flange and plug dimensions — TB01-15KNHBM/3.5 fixing flange extensions; N is the total pole count.

3.81mm KN-B dimensions

Model	Body length	First-to-last pole span	Overall height	Two-row depth	Row spacing
TB13-15KN-B/3.81	3.81P+0.56	3.81(P−1)	20.00	16.17	8.33

15KN-B 3.81mm dimensions and spring contact cross section — TB13-15KN-B/3.81 dimensions and section A–A; N is poles per row. This outline applies to the plain KN-B housing.

Ordering configuration

Specify the complete model and pitch, two rows of 2–24 poles, housing colour and any required fixing or lever option. The notation 2×P identifies the two equal rows. Colour availability depends on the selected model.
