ESD connectors are available for circular, rack and panel (ARINC), and d-sub receptacles. These connectors offer the utmost protection against EMI and ESD environments. ESD connectors have a faraday cage which protects the components inside the connector from electrostatic discharges. The composite material shell is able to resist severe corrosion up to 2000 hrs of salt spray and helps to increase durability (up to 1500 cycles).
