Description

Two-level headers with staggered PCB contacts

These pluggable PCB headers provide two stepped mating levels and 4–48 contacts in total. Each row contains 2–24 contacts. The two rows are offset along their length by half the contact pitch: 2.50mm for TB22 and 2.54mm for TB28. Vertical and right-angle versions use different PCB row spacing and solder-tail geometry.

The general ordering legend covers the wider terminal range. Its 02–99 field does not extend these headers beyond 4–48 total contacts. Screw-clamping fields do not define a wire clamp on these PCB headers, and the legend does not establish every colour or screw option for every model.

TB22 vertical header dimensions

N denotes total contacts in both rows; N/2 is the contact count in one row. All dimensional formulas below give millimetres. Distinguish one row's housing length from the full envelope of the two staggered rows.
