Introduction
Product Overview
Amphenol PT, SP, and MS/PT Series miniature cylindrical connectors are designed for general duty and environmental applications in industrial and military markets. These connectors, compliant with MIL-DTL-26482 Series 1, offer high reliability with features like bayonet coupling, resilient neoprene inserts, and gold-plated machined copper alloy contacts. They provide environmental sealing through grommet and clamp designs, operating from 55C to +125C with voltages up to 1000 VAC (RMS) at sea level. Available in solder and crimp termination styles, these connectors are intermateable with other miniature cylindrical series and offer options for hermetic sealing, coaxial contacts, and printed circuit board tails.
