Description

Eight terminal and housing configurations

TB42-45 barrier terminals have a single row of screw connections at 9.5mm pitch. C models use centered straight PCB pins, S models move the straight pins toward one housing edge, H models use perforated solder lugs, and R models use bent PCB terminals. The /A versions include mounting ends; /B versions have shorter housings without those ends.

Ordering fields

Use the required complete model, such as ULO-TB42-45S/A-XXP-Y100A. XX identifies 02–24 poles and Y identifies the color. The terminal variant and /A or /B housing must be selected together. The 45R/B attachment illustrates an 11-pole version with a variable-N length formula.

Screw head	0 slotted; 1 cross
Clamping orientation	0 screw down; 1 screw up
0A	Standard product

Dimensions and PCB layouts

All tabulated dimensions are in millimeters; N denotes pole count. Housing depth is 16.50mm and body height is 18.50mm. Terminals project beyond that height. Use each model's dimensioned views for terminal offsets and board positioning.

Housing dimension	/A models	/B models
Overall length	9.50 × (N + 2)	9.50 × N + 1.90
Central terminal body	9.50 × N + 1.90	Same as overall length
Terminal span	9.50 × (N − 1)
Mounting openings	See individual drawing; S/A and R/A mark Ø3.50 / Ø5.50	None

Models	Terminal section	Projection or offset	Additional detail
45C/A, 45C/B	1.50 × 0.80	5.00 ±0.30 tail	Centered row at 8.25 from either depth edge; Ø2.20 PCB holes; C/B end-to-first-pin distance 5.70
45S/A, 45S/B	1.50 × 0.80	5.00 ±0.30 tail	Side view marks 4.05 from the nearer edge to the pin; Ø2.20 PCB holes
45H/A, 45H/B	3.50 × 0.80	12.50 ±0.30 lug	Perforation 2.00 wide × 2.50 high
45R/A	3.50 × 0.80 shoulder; 1.50 tip width	5.00 ±0.30 horizontal reach; 5.30 ±0.30 outer drop	Ø2.20 PCB holes
45R/B	3.50 × 0.80 shoulder	5.00 ±0.30 horizontal reach; 4.70 gap to the upper terminal face	Use the 45R/B side view; the gap excludes the 0.80 terminal thickness

45C/A dimensions and PCB layout — 45C/A: mounting ends and centered PCB pins.

45C/B dimensions and PCB layout — 45C/B: compact housing with a centered pin row and 5.70mm end offset.

45S/A dimensions and PCB layout — 45S/A: mounting ends and offset pins. The dimensioned side view locates the pin 4.05mm from the nearer edge.

45S/B dimensions and PCB layout — 45S/B: offset pins without mounting ends; use the 4.05mm side-view dimension for row placement.

45H/A solder lug dimensions — 45H/A: mounting ends and 12.50±0.30mm perforated solder lugs.

45H/B solder lug dimensions — 45H/B: perforated solder lugs without mounting ends.

45R/A bent pin dimensions and PCB layout — 45R/A: mounting ends and bent PCB terminals, with the vertical dimension measured to the outer terminal face.

45R/B bent terminal dimensions — 45R/B: bent terminals without mounting ends. The 4.70mm gap and 0.80mm metal thickness are separate dimensions.
