There are many optional configurations for PT series connectors, including a vast number of insert arrangements and shell size options. A variety of finishes, which include RoHS compliant black zinc cobalt, anodic, nickel, OD Cadmium, and more, are available. PT connector shell style offerings include jam nut, box mount, wall mount, straight plug, and inline. A wide variety of backshell and strain relief options are also offered. Contacts are available in three different wire gauge sizes (12, 16, and 20AWG) with solder, crimp, PCB, coax, and thermocouple termination options. Four different contact arrangement rotations can be specified to avoid incorrect connector mating in a complex, multi-connector system.
