2 Series Single-Row Pluggable PCB Headers

Select the header configuration

The 2 series provides a single row of mating positions with vertical V, right-angle R and inclined L configurations. C versions have closed ends; M versions include fixing flanges with nuts. The 5mm LF and RF models route solder pins to opposite sides and cover 2–4 poles. The 10.16mm versions use three PCB solder tails per mating position.

Choose the complete designation, pitch, pole count, end configuration and PCB pattern. The 5.08mm 4001A versions have a distinct exposed-pin and nut-pocket construction. Similar pitch or appearance alone does not establish mating compatibility.

Model ratings and contact materials

Electrical values apply to the individual models below. IEC ratings use overvoltage category III and pollution degree 2, except the four 10.16mm models, which use category III and pollution degree 3.

2VM/5.08-4001A, 2RM/5.08-4001A and 2V/7.62 also have a general UL rating of 16A/300V without a stated use group. Keep this general rating separate from the use-group values above.

Housing, fixing nuts and environment

5mm PCB dimensions

N denotes the number of mating poles. Dimensions are in millimetres. The regular 5mm models have 1mm-square pins and a longitudinal pin span of 5(N−1). V versions mate perpendicular to the PCB, R versions parallel to it, and L versions at an incline.

The 2RM/5.0 fixing-flange edge reference is 2.54mm, within the general tolerance of the nominal 2.5mm end allowance. The 2R/5.0 and 2RC/5.0 outline views respectively show 2.54mm and 3.59mm end references; their nominal PCB end distances are 2.5mm and 3.55mm.

LF and RF side-routed pins

2LF/5.0 and 2RF/5.0 cover 2–4 poles and use opposite pin-routing directions. The two-pole outlines below specify 10mm mating length, 16.3mm housing height and a 14.6mm side-profile reference. The four-pole drawings specify 20mm mating length, 18mm housing height and the same 14.6mm side-profile reference. Do not apply these heights to an unspecified pole count.

5.08mm PCB dimensions

Regular 5.08mm models have 1mm-square pins and a longitudinal pin span of 5.08(N−1). All values in the following table are in millimetres.

For standard 2VM/5.08, the PCB end reference of 7.5mm and the 7.62mm allowance from the overall-length chain fall within the general nominal tolerance. The separate 4001A layout explicitly uses 7.62mm.

7.5mm and 7.62mm PCB dimensions

These models retain 1mm-square pins. Pin span equals pitch multiplied by (N−1). Table dimensions are in millimetres; a dash means the feature is not separately dimensioned.

10.16mm headers with three solder tails per pole

The four 10.16mm models have a 10.16mm mating pitch and three PCB rows at 5.08mm spacing, giving 10.16mm between the outer rows. Each tail has a 1×1.2mm section, 4±0.3mm projection and a 1.9mm PCB hole. The single row of mating positions must not be confused with the three solder-tail rows.

Dimensions in the table are in millimetres. The 2RC outline also identifies a 0.6mm reference projection at the end; the 2RM fixing-centre span is 10.16(N+1)mm.

General drawing tolerances

Individual tolerances take precedence. Other dimensions use the following general tolerances, in millimetres. For the 7.5mm and 7.62mm VC drawings, the second tolerance column is specifically headed PCB layout.

Ordering

Specify the series code, complete model and pitch, pole count and colour. TB21 identifies 5mm, TB27 identifies 5.08mm, TB33 identifies 7.5mm, TB39 identifies 7.62mm and TB83 identifies 10.16mm. Standard drawings use XXP for pole count and Y000A for the colour-dependent suffix. The distinct 5.08mm 4001A models retain their 001A construction suffix; do not substitute a standard 000A model.
