Connectors with built-in LEDs
LEMO was talking about a new HALO Led type configuration that includes an LED-lit flange used to display the connection status. The LEDs give users immediate visual feedback about whether the connector is securely connected and powered up. The connector includes a circular array of LEDs positioned on the connector flange. These LEDs can be either white, red, green or blue. Equipment designers can also set the connectors to display two different colors consecutively (green/red for instance), for purposes of diagnostics.
