Mini I/O – Big on Reliability, Small in Size

Big on Reliability, Small in size

When it needs to be small, it needs to be mini. TE’s Industrial Mini I/O connector provides increased reliability and vibration resistance at a quarter the size of an RJ45.

More reliable than RJ45. With only one quarter the size of conventional RJ45 plugs, the Industrial Mini I/O connector provides critical space saving on a PCB – space that can now be used more efficiently. Accidental unplugging of a network connection due to shock, vibration or pulling on cords causes expensive downtime in an industrial environment. The Mini I/Os unique locking system is specified to 100N of pull force. With its innovative piercing termination, the Mini I/O Field Installable version decreases the time usually needed to terminate the wires through soldering and with an easy to use hand tool, the field assembly in virtually any environment is now possible.
