Shimadzu Option Parts AXIAL SENSOR TARGET 3304 for TMP 3304 Series Molecular Pump

This is a product introduction and technical overview for the Shimadzu Option Parts "AXIAL SENSOR TARGET 3304" designed for the TMP-3304 series molecular pump. The AXIAL SENSOR TARGET 3304 is a precision option part used in axial magnetic-levitation sensing systems of TMP-3304 pumps to provide reliable rotor axial position reference for the levitation control electronics.

Product Overview

The AXIAL SENSOR TARGET 3304 is an OEM-compatible option part engineered to interface with the axial sensor assembly of TMP-3304 series turbo molecular pumps. Its primary role is to present a stable, repeatable target surface or magnetic signature so the axial position sensor can detect rotor displacement and maintain proper axial levitation and clearance.

Key Features

• Designed specifically for TMP-3304 series molecular pumps.
• High manufacturing precision for repeatable sensor signals and stable pump control.
• Material choices optimized for vacuum compatibility and long-term stability.
• Easy replacement design—fits into existing axial sensor target seat without pump modification.
• Quality control and inspection prior to delivery to ensure concentricity and flatness tolerances.

Function and Benefits

The axial sensor target provides a defined reference that the axial sensor reads to determine rotor position. Accurate feedback enables the pump controller to:

• Maintain correct axial levitation gap and reduce mechanical contact risk.
• Improve long-term stability and reduce vibration.
• Enhance protection against incidental rotor displacement during transient events or starts/stops.

Compatibility

Compatible model: TMP-3304 series only. For related or alternative non-standard spare parts for Shimadzu molecular pumps, please consult the relevant parts catalog or support pages such as Shimadzu molecular pump non-standard maintenance parts.

Mechanical and Material Notes

Typical construction uses vacuum-compatible materials and finishes (stainless steel, plated alloys, or specially treated surfaces) to avoid outgassing and maintain dimensional stability. Exact material and finish options depend on the supplier batch—confirm when ordering if you require a specific metallurgy or coating for bake-out or UHV use.

Installation Summary (General Guidance)

1. Power down the pump and remove high-voltage sources; allow rotor to come to rest following the manufacturer's safety procedure.
2. Access the axial sensor area per TMP-3304 service manual instructions. Work in a clean, low-particle environment.
3. Remove the old sensor target carefully—note orientation and seating surfaces.
4. Clean mating surfaces with recommended solvents compatible with vacuum hardware; avoid abrasives that change geometry.
5. Install AXIAL SENSOR TARGET 3304, ensuring correct orientation and full seating. Use specified torque values for any fasteners—do not over-torque.
6. Reassemble sensor assembly and perform sensor calibration or self-check sequence per the pump controller manual.

If you need detailed service instructions, spare part references, or calibration procedures, consult the pump service manual or contact authorized service providers. For assistance with non-standard option parts, see Non-standard option parts and maintenance.

Inspection and Maintenance

Inspect the axial target for wear, scratches, deformation, or surface contamination during routine maintenance intervals. Signs of degradation can lead to incorrect sensor readings and should be addressed immediately. Replacement is recommended if any mechanical damage or severe contamination is observed.

Ordering Information

Standard designation: AXIAL SENSOR TARGET 3304 — for TMP-3304 series. When ordering, provide:

• Pump model: TMP-3304 series
• Part name: AXIAL SENSOR TARGET 3304
• Required quantity and any special material/finish requirements

For non-standard or special-request parts and support, you can refer to the manufacturer and authorized distributors; one resource for non-standard maintenance parts is: Shimadzu molecular pump non-standard maintenance parts.

Precautions and Safety

• Always follow the TMP-3304 safety and service manual before attempting disassembly or replacement.
• Avoid contaminating the target surface—use lint-free gloves and tools rated for cleanroom or vacuum service.
• Verify sensor alignment and controller diagnostics after installation to ensure correct operation.

Packaging and Quality Assurance

Parts are typically packaged to prevent mechanical shock and particulate contamination. Each AXIAL SENSOR TARGET 3304 should be inspected for dimensional conformity and cleanliness prior to shipment. Request a certificate of conformity or inspection report if required for critical applications.
