Making the Connection Different Types of Electrical Connectors and Their Uses
Introduction • There are literally thousands of different type electrical connectors, each with their own purpose. This presentation will introduce a select few which are fairly common and readily available.
Terms and Definitions • Male – Connector with exposed metal contacts which are “plugged into” or otherwise inserted into female connector. • Female – Connector, usually with recessed contacts. • Plug – Male Connector • Jack – Female Connector
Terms and Definitions • Polarization – Connector is made so that it cannot be plugged in incorrectly. • Example: Typical “lamp cord” has one prong larger than the other: Larger (Neutral) Prong Smaller (Hot) Prong
Terms and Definitions • Positions – Number of conductors/ contacts that connector has. • Some common connectors and the number of contacts for each:

TRS Audio Connector • This Type of connector is usually used for audio applications such as for headphones, instrument cables, and patch bays. • TRS – Tip, Ring, and Sleeve Ring Tip Sleeve
TRS Audio Connector • Available in three standard diameters • ¼” • 1/8” (3.5mm) • 3/32” (2.5mm) • Features: Quick and easy connect/disconnect, ¼” size is fairly durable, up to 3 contacts.
TRS Connector • Available in Monaural (Tip and Sleeve) and Stereo (Tip, Ring, and Sleeve). ¼” Mono Plug - MPHM ¼” Stereo Plug - MPHS Stereo Panel-Mount Jack Mono Panel-Mount Jack SPHJ-S PHJ-S
Banana Connectors • Banana Connectors are very commonly found in test equipment, such as multimeters and power supplies. They are NOT polarized and are typically not safe for high voltages. Banana Jack (A.K.A. – Binding Post) Banana Plug BPL-R 5-BP-B
Banana Connectors • Features: Good for currents up to approximately 10A, Good general purpose DC connector. • This is the type of connector used for the 12VDC connections on the Grid. Available in Pairs as well. Slot on one side of connector Typically denotes “Negative” side. BP-2 Shown
“RJ” Series Jacks and Plugs • The “RJ” series plugs and jacks are typically used for communications connects. The RJ-11 and RJ-12 connectors are used for telephone connects, and the RJ-45 is most frequently used for CAT-5 Networking cable. RJ-45 RJ-11/12
“RJ” Series Jacks and Plugs • Features: This type of connector is polarized, very inexpensive, and very common. • Drawbacks: These connectors can handle only small amounts of current and require a crimper to connect to cable.
“RJ” Series Jacks and Plugs • Jacks: RJ-12 Jack w/ Leads RJ-11 Wall Plate Jack MT-107 MT-61
“Molex” Multi-pin Connectors • Good general-purpose polarized power connectors. Available in 2 to 15 positions. • Requires some time wiring. 2 Position “Molex” connector Available from Radio Shack
“Cinch Jones” Multi-Pin Connectors • “Cinch Jones” connectors are very sturdy, polarized connectors capable of handling up to 10A. Available from www.mouser.com
