DC Input Jacks & Plugs

Body: 

Switchcraft’s DC Power input jacks feature a sleeve shunt spring that allows you to switch from DC to AC supply for your product. Typically this is used to change the unit from operating on the battery to either operating on AC voltage or charging the battery, or both. Additional switching circuits are also available.

DC Power input jacks are available in PC Board mount and Panel mount varieties. Many are compatible with automated manufacturing equipment. There are several pin sizes available:  2.5, 2.1, 2.03, 2.0 and 1.27mm.

Slip Rings 103: Defining the System Interface

Body: 

Slip rings are available in two basic mechanical configurations: drum style and platter style. Drum style has many advantages for most designs. Platter style is best for applications with limited length availability.

Drum style slip rings are available with and without through bores to pass fluid and pneumatic lines, waveguides, etc.  Sometimes it makes the most sense to use a through bore style for the power circuits and place a miniature slip ring capsule in the center.
