Amphenol ST^® Connector, Multimode, 128µm (micron) Ceramic Ferrule, Plastic Body, 900µm & 3mm Boot

The Amphenol Standard ST^® Connector (Straight Tip) features a secure bayonet fiber optic connector (BFOC) with a push-to-turn locking mechanism that ensures positive engagement while preventing overtightening and fiber face damage. Compatible with large-core fibers, this ST fiber connector is commonly used in applications such as temperature, pressure, and semiconductor test connectors, medical devices (non-MRI), and the semiconductor industry. It is also utilized in power transformers, EV testing, instrumentation, and high-voltage temperature measurement systems.

The Multimode ST Connector has a plastic body and a zirconia ferrule. A black strain relief boot is included to provide added protection for fiber optic cables.
