Product Overview

Amphenol PT, SP, and MS/PT Series miniature cylindrical connectors, based on MIL-DTL-26482, Series 1 specifications, offer high reliability and design flexibility for general duty and environmental applications. These connectors provide twice the number of contacts in half the size of standard connectors. They are suitable for a wide range of industrial and military markets, including instrumentation, monitoring equipment, machine tool automation, communications, geophysical exploration, industrial controls, robotics, rail/mass transit, and military/aerospace sectors. Key features include environmental sealing, a wide operating temperature range (-55C to +125C), and high voltage ratings up to 1000 VAC (RMS) at sea level. Contacts are machined from gold-plated copper alloy for corrosion resistance and indefinite shelf life. Available in both solder and crimp termination styles, with bayonet coupling for secure mating.
