Additional Miniature Cylindrical Connectorsoffered by AmphenolMiniature CylindricalProprietary/MIL-C-26482, Series 1 & 2ConnectorsThere are several additional connector series withinthe Amphenol ® MIL-C-26482 and similar types family.Each series offers varying design characteristicsand customer options to meet costconsiderations and to provide users with the mostdesign flexibility possible.The additional series within the Amphenol Miniature CylindricalFamily of Connectors are shown in detail in Amphenol catalog12-070, which can be supplied upon request. Briefly these additionalproducts are described as follows:• PT, SP, MS/PTProprietary/MIL-C-26482, Series 1These are bayonet type with solder contacts. Both the insertand main joint gasket are molded from resilient neoprene.This provides excellent moisture sealing at the gasket andsuperior electrical isolation of the contact in the inserts.Socket contacts are closed entry design. Printed circuitboard contacts are also available in this series.The SP is a modification of the PT providing special shellswith a wide mounting flange for back panel mounting. TheSP also has a durable non-conductive hard anodic “Alumilite”coating which provides abrasion and corrosion protection.There are 8 shell styles in the PT, SP and MS/PT series, andshell sizes are 6-24. The PT solder is UL recognized. Hermeticsare also available.• PT-SE, SP-SE, MS/PT-SEProprietary/MIL-C-26482, Series 1These are a derivative of the PT line, bayonet type. However,they incorporate crimp contacts that are rear insertable,front releasable. An MS approved spring towerretention system holds the contacts in place.• PT-CE, SP-CEProprietary crimp typeAnother derivative of the PT line, bayonet type. These alsohave crimp contacts that are rear insertable, front releasable,but the contacts are held in place by a nylon waferretention system. The voidless one-piece insert and grommetassembly provide continuous dielectric separationbetween contacts.• PC, PC-SE, PC-CEProprietary solder and crimp typeThe PC series within the Amphenol ® miniature cylindricalfamily is threaded coupling, rather than bayonet coupling.The threads are double-stubbed so they can not be crossthreaded.The PC is offered with solder contacts. The PC-SE hascrimp contacts in a spring tower retention system, while thePC-CE has crimp contacts in a nylon wafer retention system.Hermetics are availableAll miniature cylindricals are intermateable and intermountablewith each other except for the threaded coupling PC Series.For further information ask for catalog 12-070.
