Industrial Connector Amphenol GTS030-20-27P Designed for Quick Positive Coupling and Signal Transmission
Product Overview
Amphenol ACA-B and GT Series Connectors are heavy-duty, reverse bayonet coupling connectors designed for commercial and industrial environments requiring rugged, reliable connections for power and signal applications. These connectors are manufactured to MIL-DTL-5015 and SAE AS50151 standards, offering quick positive coupling with audible, tactile, and visual indication of full coupling. They are waterproof (IP67 rated), resistant to high shock and vibration, and do not require lockwiring. Common applications include automation, machine tool, robotics, instrumentation, process control, material handling, and test and measurement. The GT series is also preferred for mass transit applications.
