T42-1 Push-In Terminals For Circuit Boards

  These pins are a less expensive alternative to screw type terminal blocks for use on printed circuit boards. They are described as "Push-In Terminals for 0.042" Diameter Holes" and require soldering of external connections.

  While not as convenient as regular terminal blocks they are considerably less expensive and would be easy use where access is not restricted and if a terminal on a board is not to be used the Push-In Terminal could simply be left off the board.

  Many holes for PCB terminal blocks are slightly larger than 0.042" Diameter but the pins can usually be splayed open for a good fit.

  When installing these pins, do not apply too much solder as the wire insertion area of the pin will fill with the excess solder.

Please Read Before Using These Circuit Ideas

  The explanations for the circuits on these pages cannot hope to cover every situation on every layout. For this reason be prepared to do some experimenting to get the results you want. This is especially true of circuits such as the "Across Track Infrared Detection" circuits and any other circuit that relies on other than direct electronic inputs, such as switches.

  If you use any of these circuit ideas, ask your parts supplier for a copy of the manufacturers data sheets for any components that you have not used before. These sheets contain a wealth of data and circuit design information that no electronic or print article could approach and will save time and perhaps damage to the components themselves. These data sheets can often be found on the web site of the device manufacturers.

  Although the circuits are functional the pages are not meant to be full descriptions of each circuit but rather as guides for adapting them for use by others. If you have any questions or comments please send them to the email address on the Circuit Index page.
