330103-00-21-10-11-CN is a metric 3300 XL 8 mm proximity probe with an M10 × 1 case, 210 mm overall length and a 1.0 m total probe length with FluidLoc cable. Its unthreaded-length code is 00, so the case is threaded to the sensing-end region.
FluidLoc construction on 330103-00-21-10-11-CN is intended to limit oil migration through the cable interior, while option 11 adds a protector around the ClickLoc connection. The probe itself is not armored, so routing and support should suit the installed machine environment.
Within a correctly configured, interchangeable 3300 XL 8 mm system, 330103-00-21-10-11-CN and the extension-cable length must add up to the Proximitor Sensor system length. The CN suffix identifies the published China hazardous-area ordering option; project markings should be checked against the delivered nameplate.
