(CMC) is the better fit, here is a relatively comprehensive list of parameters to consider: ■ Gender (Male/Female): The male end incorporates the contact pins that plug into the female sockets (Figures 4 and 5). Most plugs and receptacles are designed to mate within their own brand or manufacturer. Connectors from different manufacturers typically do not interconnect, so in general, connectors will be sourced as a mated pair. ■ Number of Contacts: The number of conductive pins in the connector required to carry the signals, data, or power. This number can range from 1 into the hundreds. ■ Termination: How the wire or cable will mate with the conductive contacts in the connector, including solder, wire wrap, lugs, or crimping. ■ Contact Size: The diameter of the individual contacts or gauge of wire that can mate with each contact. ■ Voltage & Current Rating: The maximum voltage, expressed as volts (V), or current, expressed as amps (A), that the connector is designed to carry.
■ Insertion Frequency: How often the connector will be connected and disconnected. Also known as mating cycles, the frequency of connection may require a more robust connector or cable protection accessory. ■ Mounting Style: Common mounting options include cable mount, panel mount, or surface mount. ■ Coupling or Locking Style: Offers secure mating of the connector and can include bayonet, latch, push-pull, threaded, and quick-disconnect. ■ Backshell Type: Threaded onto the cable side of a circular connector to offer secure cable support, backshell types include straight, right angle, braid tail, spring, strain relief, sealed, and crimped. ■ Materials Used: Common materials used for the connector body are stainless steel, aluminum, plastic, composite, or brass, depending on design requirements and budget. ■ Ingress Protection: IP ratings are defined by the IEC 60529 standard that covers protection against solids and liquids entering the body of the connector. ANSI 60529 covers IP in the United States and EN 60529 covers it in Europe.
■ Plugs & Sockets: There is no standard naming convention so different manufacturers may use alternate terms, but typically sockets and jacks are associated with panel mounted circular connectors, while plugs relate to circular connector cable assemblies. Conclusion Will the connector be exposed to environmental contaminants or subject to immersion? Does the connector require protection from EMI or RFI signals? Will the connector be subject to excessive vibration or frequent impacts? The answers to each of these will help determine the quality, features, and accessories needed, but regardless, circular connectors have proven to be a reliable and rugged interconnect solution when dealing with harsh application conditions. Same Sky offers a diverse range of circular connectors and circular cable assemblies that can meet these design challenges head on.
