223632 – ERNI

The ERNI 223632 is a female connector insert from the ERmet HM series, specifically designed for high-speed, hard metric backplane applications. This component features a HM-A footprint, indicating compatibility with standard ERmet HM male connectors. The “FST” designation signifies a Fast Straight Termination, optimized for press-fit assembly into plated through-holes on a printed circuit board, ensuring a robust and reliable mechanical and electrical connection. The “no shield” specification indicates the absence of electromagnetic interference (EMI) shielding, making it suitable for applications where EMI is not a primary concern or is addressed through other system-level mitigation techniques. “Selective loading” refers to the deliberate omission of specific contacts within the connector body, allowing for customization of signal routing and impedance matching to optimize signal integrity for particular application requirements. This selective population can be used to manage crosstalk or to accommodate specific signal assignments within the backplane architecture.
