330878-90-00: 3300 XL 50 mm Proximitor Sensor configured for 9.0 meters (29.5 feet) system length, panel mounting, and no agency approvals.
The 3300 XL 50 mm proximity transducer system consists of a separate 50 mm probe, extension cable, and Proximitor sensor. It offers a maximum linear range of 27.9 mm (1100 mils) to measure differential expansion (DE) or rotor expansion (RX) on large steam turbine generators. Unlike variants with option codes -50 or -51 (5.0 m system length) or those configured for DIN-rail mounting (options -51 and -91), this panel-mounted 9.0-meter option (90) matches with a 1.0 m probe and an 8.0 m extension cable, or a 9.0 m total calibration length. The -00 agency option specifies a configuration where hazardous area certifications are not required.

| OUT | Signal Voltage Output (approximately -1.5 Vdc to -12.5 Vdc) |
| COM | Signal Common / Ground Reference |
The Proximitor Sensor utilizes SpringLoc terminal strips requiring no special tools for field wiring, supporting conductors from 0.2 to 1.5 mm2 (16 to 24 AWG). A three-conductor shielded triad cable is recommended for signal routing. When installing, ensure that the total system length (9.0 meters) corresponds precisely to the probe and extension cable combined lengths. The panel mount bracket is secured to the panel using the mounting holes provided in the base plate.
