Industrial Grade Miniature Connector Amphenol PTB-24-61PSZ with Solder and Crimp Termination Options
Amphenol PT, SP, MS/PT Series Miniature Cylindrical Connectors
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 offer high reliability with features like bayonet coupling, resilient inserts, and gold-plated machined contacts. They are suitable for instrumentation, monitoring equipment, machine tool automation, communications, industrial controls, robotics, and military/aerospace sectors. The series includes both MS-approved and proprietary styles, providing design flexibility with options for solder or crimp termination, various shell styles, insert arrangements, and specialized features like hermetic sealing and PCB contacts.
Key Advantages:
- Double the number of contacts in half the size of standard connectors.
- Environmental sealing achieved through grommet and clamp design.
- Wide operating temperature range (-55C to +125C).
- High dielectric strength and moisture barrier from resilient inserts.
- Machined, gold-plated copper alloy contacts for corrosion resistance and indefinite shelf life.
- Reliable mating with 5 key/keyway polarization and 3-point bayonet coupling.
- Intermateable with all miniature series connectors.
