1.3 Connectors

The 3-lead Contact package can be used with either compression or pogo-pin connectors. The choice depends on the overall solution of how the device must come into contact with the connector. The choice may also be different in an end application vs. a manufacturing environment.

Compression Connectors

The 3-lead Contact package is intended to be used with 2 mm pitch compression connectors. They can be standard off-the-shelf connectors or a custom connector can be created for a given application. The standard connectors listed below, or those with similar dimensions and mechanical characteristics, can be used with this package:
  • AVX Corporation 9155-800
  • Molex® 1050400001
Appendix C provides more details on these compression connectors.

Pogo-Pin Connectors

Pogo-pin connectors can be used instead of compression connectors. Pogo pins are spring-loaded connectors. Pins can come in different lengths and widths, and can have a different stroke length. Individual pogo pins can be implemented in a design, or a connector of three pins can be implemented. The pogo pins must be placed on the 2 mm center for optimal placement.

  • Mill-Max Mfg. Corporation 3-pin Through Hole Connector: 836-22-003-10-001101
  • Preci-Dip 3-pin Surface Mount Connector: 821-S1-003-30-015101 has more details on these compression connectors
Appendix D provides more details on these pogo-pin connectors.

Pogo pins, depending on the connector, can sometimes be readily replaced; so in a manufacturing environment, this may be a preferred solution. Pogo-pin connectors, where the length of each pin can be different, provide some additional flexibility in the manufacturing environment to minimize ESD damage (see ESD System Design Considerations).
