Durable Miniature Cylindrical Connectors Including Amphenol PTB-22-36PS Suitable for Harsh Environments
Amphenol Miniature Cylindrical Connectors - PT, SP, MS/PT Series
Product Overview
Amphenol Miniature Cylindrical Connectors, including the PT, SP, and MS/PT Series, are designed for general duty and environmental applications in both industrial and military markets. These connectors offer high reliability and design flexibility, providing twice the number of contacts in half the size of standard connectors. They are suitable for demanding applications requiring environmental sealing or pressurized connections. Key markets include instrumentation, monitoring equipment, machine tool, factory automation, communications, geophysical, industrial controls and robotics, oil and petrochemical industries, rail/mass transit, and military/aerospace.
