Gefran PC-M-0300 0000X000X00 300 mm Position Transducer
Product Identity and Intended Use
The Gefran PC-M-0300 0000X000X00, ordering number F003878, is a PC-series cylindrical potentiometric transducer configured for 300 mm of linear travel. It is intended for continuous position monitoring on longer moving assemblies where jointed mounting is more suitable than attaching a rigid profile sensor directly to a machine frame.
The sensor’s self-aligning rod-eye arrangement permits the transducer to follow an articulated linkage while maintaining continuous absolute feedback. Typical uses include actuator position measurement, material-handling mechanisms, movable machine sections and other equipment with a defined 300 mm working range.
What Distinguishes F003878
- Verified complete model string: PC-M-0300 0000X000X00.
- Gefran ordering number: F003878.
- 300 mm electrical stroke rather than the 100 mm stroke of F003846.
- Cylindrical body with jointed mounting instead of an LT-series profile installation.
- Longer mechanical envelope requiring independent pin-center and clearance checks.

Long-Stroke Installation Requirements
The extended length of a 300 mm transducer creates different installation constraints from shorter PC versions. Check for adequate clearance through the complete machine cycle, including surrounding guards, hoses and moving structures. The mounting pins should allow free articulation without axial binding, and the linkage must not exceed the sensor’s mechanical stroke at either travel limit.
Record both retracted and extended pin-center distances before replacement. A sensor with similar appearance but a different stroke cannot be corrected merely by rescaling the controller if its physical length prevents proper installation.
Control-System and Calibration Checks
Verify the excitation voltage, signal polarity, resistance configuration and analogue input scaling from the machine documentation. If the existing control system was calibrated for a shorter stroke, installing a 300 mm version may alter the displacement represented by a given output voltage. Any calibration change should follow the machine manufacturer’s commissioning procedure.
Related PC and Profile-Mounted Sensors
The PC-M-0100 0000X000X00 F003846 has a 100 mm stroke and a substantially shorter mounting envelope. The LT-M-0200-S 0000X000X00 F003538 provides 200 mm travel but uses a profile-style installation rather than PC rod-eye mounting. These differences affect linkage design, installation length and controller scaling.
Related models are provided for family reference only and are not automatically interchangeable.
Ordering and Condition Verification
Use F003878 together with the complete model string when requesting this product. Confirm the nameplate, stroke, mounting dimensions, connector, configuration characters and component condition. Photographs should show the identification label, both mounting joints and the electrical interface. Suggested internal-link anchor text is “Gefran PC-M-0300 300 mm Rod-Eye Position Sensor." No stock, lifecycle or interchangeability claim should be made without supplier or manufacturer confirmation.
