HC-49/U, HC-49/T, HC-50/U Series
H49MJ, 49TMJ Series  (158 k bytes)
 |
- The H49/U and H50/U series are the resistance-weld version of the old solder seal types HC-18/U and HC-25/U respectively. They are physically interchangeable.
- No solder or flux involved in the sealing process. Low aging.
- HC-49/U is wire lead type and HC-50/U is plug-in type.
- Two different holder heights to choose from: 13.6mm and 11.2mm.
