Gefran PY-2-C-010 0000X000X00 Spring-Return Transducer

Short-Stroke Contact Measurement

The Gefran PY-2-C-010 0000X000X00 is a PY2-series spring-return potentiometric transducer with a 10 mm measuring stroke. The exact Gefran ordering number is F004190. It uses a stainless-steel ball tip to follow the surface of a moving component, while the internal return spring keeps the probe in contact with the measured target.

This operating method differs from rod-eye and profile-mounted displacement sensors. The PY2 probe is suited to short-stroke inspection, dimensional movement monitoring, fixture position feedback and machine mechanisms where the target acts directly against the spring-loaded tip.

Configuration Details

Ball-Tip and Return-Spring Considerations

The ball tip is intended to contact the moving surface without requiring a separate mechanical linkage. Mount the body so that target movement follows the probe axis. Lateral loading, a rough target surface or impact at excessive speed can wear the ball, bend the control rod or produce unstable readings.

The machine should not force the probe beyond its permitted travel. Confirm the installed preload and make sure the return spring maintains contact throughout the required measurement cycle without reaching a mechanical end stop.

C Connector Versus F Cable Version

The “C" designation identifies the PY2 version with a 5-pole DIN 43322 connector. PY-2-F variants use a three-wire screened cable and therefore require different cable routing and termination. A PY-2-F-010-S01M cable version should not be ordered as a connector-version replacement unless the wiring arrangement and installation requirements have been deliberately reviewed.

Stroke and Tip Comparisons

The PY-2-C-025 0000X000X00 F004199 provides a 25 mm stroke, while the PY-2-C-050 0000X000X00 F004207 provides 50 mm travel. Both require more axial installation space and different signal scaling than the 10 mm F004190 version. The Gefran PY3 family uses a precision bearing tip instead of the PY2 stainless-steel ball tip, which changes the mechanical contact arrangement.

Maintenance and Replacement Verification

Inspect the probe for smooth spring return, tip damage, contamination and side loading. Before ordering, confirm F004190, the full 0000X000X00 configuration, 10 mm stroke, C connector, terminal arrangement and M2.5 ball-tip construction. Market listings containing additional characters such as XL0202 or L000X000X00 represent different configurations and must not be merged with this page.

Inquiry and Supply Notes

Provide a readable nameplate photograph and images of the probe tip and connector with the inquiry. Suggested internal-link anchor text is “Gefran PY2 10 mm, 25 mm and 50 mm Spring-Return Transducers." Product condition, availability and delivery terms require separate confirmation.
