OSTW Series connectors are standard size round pin 2 pole TC connectors. They connect or extend TC wire and cable to thermocouple sensors, temperature instrumentation and process controllers.This popular series of TC connector is available in all thermocouple calibration code colors. The contact washer feature allows the installer to use a straight wire strip. This greatly cuts installation/termination time and eliminates the torque that is normally associated with wire that is looped around a termination screw.
