Description

PCB socket configurations

The 2A and 2B family provides a single row of mating contacts and two through-hole solder tails for each pole. B and BM versions mate vertically to the PCB; A and AM versions mate parallel to the PCB. M versions add fixing flanges at both ends. Select the complete model, pitch and pole count to match the PCB footprint and mating connector.

Materials and operating conditions

Property	Specification
Housing	PA66, insulation material group I
Flammability classification	UL94V-0
Contacts and solder pins	Tin-plated brass
Protection degree	IP20
Operating temperature	-40°C to +105°C

These models are PCB socket components. Wire sizes, stripping lengths and wire-clamping torques are not specified for them. Fixing screw size and tightening torque for M versions are also not specified.

5.0mm outline and PCB dimensions

N is the number of poles. All eight models use a 5.08mm transverse spacing between the two solder-tail rows. This row spacing is distinct from the 5.0mm or 5.08mm pole pitch along the connector.

Models	Core body length	Body depth across mating face	Body length along mating axis	Additional dimensions
TB24-2B/5.0	5.0 × (N − 1) + 7.0mm	8.54mm	19.1±0.1mm	Mating-end section 8.35mm; solder-pin width 1.10mm
TB24-2BM/5.0	5.0 × (N − 1) + 7.0mm, excluding flanges		19.1±0.1mm	Mating-end section 8.35mm; pin width 1.10mm; PCB edge to first pin row 1.36mm
TB24-2A/5.0	5.0 × (N − 1) + 7.0mm		19.1mm	Near pin row to body edge 2.8mm
TB24-2AM/5.0	5.0 × (N − 1) + 7.0mm, excluding flanges		19.1mm	Near pin row to body edge 2.8mm; fixing-hole centre to first pole centre 5.08mm

The pole-centre span is 5.0 × (N − 1)mm. The overall flange length is not dimensioned for the 5.0mm M models.

2B 5.0mm vertical PCB socket outline and section — TB24-2B/5.0: vertical socket with 5.0mm pole pitch and 5.08mm solder-tail row spacing.

2BM 5.0mm flanged socket dimensions and PCB layout — TB24-2BM/5.0: flange version with two aligned rows of PCB holes on a 5.0mm longitudinal pitch.

2A 5.0mm right-angle socket outline and section — TB24-2A/5.0: right-angle solder tails with 5.08mm row spacing and a 2.8mm edge offset.

2AM 5.0mm flanged right-angle socket and PCB layout — TB24-2AM/5.0: flanged right-angle socket; the 5.08mm fixing-hole offset is separate from the 5.0mm pole pitch.

5.08mm outline and PCB dimensions

TB30-2B/5.08	Overall: 5.08 × (N − 1) + 7.08mm	8.50±0.10mm	19.1±0.1mm	Mating-end section 8.35mm; pin width 1.10mm
TB30-2BM/5.08	Overall including flanges: 5.08 × (N + 2)mm	8.50±0.10mm	19.1±0.1mm	Flange depth 6.90mm; mating-end section 8.30mm; pin width 1.10mm
TB30-2A/5.08	Overall: 5.08 × (N − 1) + 7.08mm	8.5mm	19.1mm	Near pin row to body edge 2.8mm
TB30-2AM/5.08	Core: 5.08 × (N − 1) + 7.08mm; overall including flanges: 5.08 × (N + 2)mm	8.5mm	19.1mm	Flange depth 6.90mm; near pin row to edge 2.8mm; solder-tail projection 3.50±0.30mm

The pole-centre span is 5.08 × (N − 1)mm. Use the individual model drawing for the end-flange arrangement and PCB mounting details.

2B 5.08mm vertical PCB socket dimensions — TB30-2B/5.08: vertical socket dimensions and section through the contact and solder tails.

2BM 5.08mm flanged vertical socket dimensions — TB30-2BM/5.08: overall flange length is 5.08 × (N + 2)mm.

2A 5.08mm right-angle PCB socket dimensions — TB30-2A/5.08: right-angle socket with 5.08mm pole pitch and solder-tail row spacing.

Ordering and matching

Specify the complete TB24 or TB30 model, the required 02–24 pole count, colour code and any customer option code. Keep the selected orientation, flange arrangement and pitch together when comparing the mating connector and PCB layout.
