The 500, 531, 531-SL, 521 and 521-SL series of high voltage connectors, kits and cable assemblies are designed to minimize the risk of electrical shock to personnel through the use of recessed contacts. Both the receptacle and plug connectors have recessed contacts positioned to stand-off the rated voltage in the unmated condition at sea level of each respective series.

In addition to the recessed contact, the connectors also feature a spring finger body contact which assures a reliable ground circuit prior to engagement of the center contact; further reducing the risk of electrical shock.

Operating Temperature Range
-40 to 85°C
