136HT terminal blocks connect field wiring to a PCB through a rising-clamp screw terminal and two solder pins per pole. Three pitches provide separate board-layout choices. Wiring enters through the front opening, with screw access from above.
| Model | Pitch | Connection rows | PCB arrangement | Pole-count range |

The UL tightening value for 136HT/12.7 and 136HT/15.24 is 10.53lbf·in.
Dimensions are in mm; P denotes the number of poles. The 12.7mm version has a 30.65mm housing height above its mounting face and a nominal 35.65mm overall height including the 5mm solder tails. The 10.16mm and 15.24mm versions have a 35.30mm overall height. Do not substitute one pitch layout for another.

The section and PCB layouts locate the first transverse pin row 3.20mm from the indicated body reference edge. Pin thickness is 0.90mm; the 10.16mm model also specifies a 1.50mm pin width. The 12.7mm PCB layout specifies Ø2.00mm holes. End offsets use the reference edges shown in each drawing, including the distinction between the main housing edge and its projecting side feature.
Specify TB37-136HT with the required pitch, pole count, colour code and customer option field. The order format uses XXP for the number of poles and Y000A for the colour and customer requirements.
