This product page describes the Axial Sensor Target — an original Shimadzu option part used as an axial magnetic levitation positioning element for TMP-803 and 1503 series turbomolecular pumps. It is supplied as an OEM repair component intended to restore correct axial sensing and positioning performance in affected molecular pumps.
Key description
The Axial Sensor Target is the dedicated target element that works with the pump’s axial magnetic sensing assembly. It provides a repeatable magnetic reference for the axial levitation/position control system in TMP-803 and 1503 series molecular pumps. Supplied as an original spare part for repair and replacement, it helps ensure the pump’s rotor is accurately centered and axially stabilized under high-speed operation.
Applications & compatibility
- Designed specifically for TMP-803 and 1503 series Shimadzu turbomolecular pumps.
- Intended for use in repair, refurbishment or preventive maintenance of axial magnetic levitation assemblies.
- If you are ordering a set of non-standard maintenance or repair components for Shimadzu pumps, see our dedicated parts page: Shimadzu molecular pump non-standard maintenance parts.
Typical features
- OEM original part specification to match the factory axial sensor geometry and magnetic response.
- Precision machined target surface and magnetic material selection to maintain stable axial sensing.
- Balanced and verified for concentricity to minimize rotor imbalance after installation.
- Supplied ready for installation (may include fastening screws or alignment shims as applicable).
Installation notes
- Only qualified service personnel should remove and replace axial sensing components. Follow the pump service manual for disassembly sequence, cleaning and reassembly torque values.
- Maintain a clean, particle-free environment when handling the target. Even small particles on the target surface can affect magnetic sensing accuracy.
- During installation, verify axial clearance and sensor output per factory alignment procedure. After installation, perform recommended rotor spin and balancing checks.
- If you require guidance or additional non-standard replacement parts, visit our parts resource: Shimadzu Option Parts axial components.
Maintenance & inspection
- Inspect the target for surface damage, wear or contamination during pump service intervals.
- Replace the target if machining marks, scratches or mechanical deformation are observed, or if axial sensor diagnostics indicate degraded performance.
- Keep replacement parts in anti-static, clean packaging until installation to prevent corrosion or contamination.
Troubleshooting tips
- Symptom: axial instability or frequent axial trips — check target seating, contamination and sensor gap. Replace the target if alignment cannot be restored.
- Symptom: unusual vibration after replacement — re-check balance, concentricity and tighten fasteners to specified torque. Ensure no foreign objects remain in the rotor chamber.
- Symptom: inconsistent sensor readings — verify sensor electronics and cable integrity as well as correct target orientation.

Ordering information
When requesting a quote or placing an order, please provide the pump model (TMP-803 or 1503 series), serial number, and the service context (repair or preventive replacement). This ensures correct selection of the axial sensor target and any accompanying alignment accessories.
Safety
Follow all lockout/tagout procedures and ensure the pump is fully de-energized and free of hazardous gases before opening the vacuum chamber. Use appropriate ESD precautions with electronic or magnetic components.
For additional technical questions, compatibility confirmation or to request a quotation, contact your authorized parts supplier and reference the TMP-803 / 1503 series axial sensor target requirement.
