RJ45 jacks integrate mis-mating protection

From Suyin comes 12-pin, low-profile, in-board RJ45 jacks that measure 18.05mm x 20.25mm x 11.45mm and can be installed on the board in an offset manner to save further space.

The 100073FR012S173ZL (halogenated) and 100073HR012S173ZL (optionally free of halogen) series of RJ45 jacks, when installed in an offset manner, can reduce their height above the circuit board by 2mm to 9.45mm.

As an additional distinctive feature, two springs are contained within the housing to provide mis-mating protection by ensuring that other types of connectors, such as telephone connectors, cannot be inserted.

The matching plug can only be inserted when these springs are pressed down completely. These unique characteristics are supplemented by other features, such as two integrated LEDs (green and yellow) as well as extensive shielding measures that have been implemented on the sides and in the upper portion of the connector to reliably prevent electromagnetic radiation and interference.

Two soldering brackets located on the sides improve the connector's grounding connection and provide it with high mechanical retention forces on the board.

The service life is specified at a minimum of at least 5,000 mating cycles, operating temperatures range from -40°C to +105°C, and the maximum electrical load capacity per pin is rated at 11Vdc and 1.5Adc.

Typical fields of application include space-critical broadband data connections in 10/100/1000Base-T Ethernet networks in the telecommunications and consumer goods industry and in medical device electronics.
