General Specifications




   Micro Connector
 
     Micro connectors and nano connectors exhibit contacts with a pitch of 0.05" (micro) and 0.025'' (nano), respectively. 
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Gender       
   Your choices are...
 
      
 
   Male / Plug
 
     Male connectors or plugs are often referred to as header or free connectors. In coaxial RF connectors, the plug is normally the movable portion and is usually attached to a cable or removable sub-assembly. In shell type multiple-contact connectors, the plug usually contains the socket contacts and is mounted on the "hot" (rack) side of the system. Plugs mate with receptacles, jacks, outlets, etc.
 
   Female / Jack
 
     Female connectors or jacks are connecting devices into which plugs are inserted to make circuit connections.
 
   Other
 
     Other unlisted gender type.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Geometry       
   Your choices are...
 
      
 
   Straight
 
     The connector does not bend.
 
   Right Angle
 
     The connector is bent at a right angle.
 
   Other
 
     Other unlisted geometry.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Mounting Style       
   Your choices are...
 
      
 
   Surface Mount (SMT)
 
     Surface mount technology (SMT) places small components on the surface of a printed circuit board. Soldering permanently attaches connectors to PCB traces. Unlike PC mount connectors, however, SMT connectors do not require drilled holes in the PCB. Using smaller components allows for higher frequencies of operation, smaller board size, etc.  
 
   PC Mount
 
     Connectors directly attach to the printed circuit board through pre-drilled holes in the board. Soldering permanently attaches connectors to PCB traces.
 
   Receptacle / Dummy Receptacle
 
     Connectors with receptacle mounting are used in applications where the connector is required to fit a panel cutout. Dummy receptacles are receptacles that do not have provisions for attaching conductors. They are generally used for storage of a cable assembly connector plug.
 
   Other
 
     Other unlisted, specialized, or proprietary styles.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
Applications




   Applications / Categories       
   Your choices are...
 
      
 
   SCSI Connectors
 
     Small computer system interface (SCSI) connectors are used to connect peripherals to computers. These connectors are parallel devices.
 
   PCB Connectors
 
     Printed circuit board (PCB) connectors include USB, BNC, Centronics and D-Subminiature connectors, as well as headers, sockets, etc.
 
   IEEE 1284 Connectors
 
     IEEE 1284 connectors use a parallel port protocol. Three connectors conform to the IEEE 1284 standard: 1284 Type A (25-pin DB-25 connectors), 1284 Type B (full-size Centronics connectors), and 1284 Type C (half-size Centronics connectors).
 
   Other
 
     Other unlisted application types.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
RoHS Compliance




   RoHS Compliant
 
     Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006.
 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
Performance
The maximum current or maximum voltage defined by an approval organization may differ from the supplier's maximums. In many cases, the product can be used safely at an unapproved level. Check with the supplier for specific usage details.



   Number of Contacts
 
     The number of contacts is the number of conductive elements that mate with a corresponding element to provide an electrical path.
 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Contact Resistance
 
     Contact resistance is the measurement of electrical resistance of mated contacts when assembled in a connector under typical service use. Electrical resistance is determined by measuring from the rear of the contact area of one contact to the rear of the contact area of its mate (excluding both crimps) while carrying a specified test current. Overall contact resistance would be the wire-to-wire measurement.
 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Insulation Resistance
 
     Insulation resistance is the electric resistance between two conductors separated by an insulating material.
 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
More Specs




   Contact Plating      The contacts of a connector are conductive element in a termination assembly that mates with a corresponding element for the purpose of transferring electrical energy. Plating is the overlaying of a thin coating of metal on metallic components to improve conductivity, provide for easy soldering or prevent rusting or corrosion.
   Your choices are...
 
      
 
   None
 
     The connector contacts are not plated.
 
   Copper Plating
 
     Connector is available with gold-plated contacts copper.
 
   Gold Plating
 
     Connector is available with gold-plated contacts, for a more reliable electrical connection. Gold-plated contacts are more expensive than silver-plated or copper contacts, and are generally offered as an upgraded connector.
 
   Nickel Plating
 
     The connector is available with nickel-plated contacts.
 
   Silver Plating
 
     Connector is available with silver-plated contacts.
 
   Other
 
     Other unlisted, specialty, or proprietary contact plating.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Housing Material       
   Your choices are...
 
      
 
   Metal
 
     Housing is constructed of metal.
 
   Plastic
 
     Housing is constructed of plastic.
 
   Other
 
     Other unlisted or proprietary housing material.
 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
