Shimadzu Option Parts AXIAL SENSOR UNIT ASSY V2304 for TMP-V2304 series Molecular pump

The Shimadzu Option Parts AXIAL SENSOR UNIT ASSY V2304 is a precision axial magnetic-floating sensor assembly designed for use with Shimadzu TMP-V2304 series molecular pumps. This unit is intended as an original-equipment repair rotor/sensor component and is also suitable for repair and refurbishment across the TMP-V1804 to TMP-V2304 family where axial sensing and rotor stabilization are required.

Functionally, the axial sensor unit monitors the rotor’s axial displacement and provides a stable feedback signal to the pump’s controller. Accurate axial sensing prevents unintended rotor-stator contact, reduces wear, and supports high-speed stable operation. When installed correctly, this assembly helps maintain vacuum performance, lowers vibration levels, and extends the life of the pump rotor system.

Compatibility and fitment: designed specifically for TMP-V2304 series molecular pumps, and applicable across refurbishing operations for TMP-V1804 up to TMP-V2304 rotors. For complementary non-standard maintenance parts and related repair items, see Shimadzu molecular pump non-standard maintenance parts.

Installation and service notes:

• Always follow Shimadzu service manual instructions for disassembly/reassembly of the pump and rotor. Improper handling can damage bearings or magnetic surfaces.
• Use cleanroom practices when handling sensors and rotor components — oils, particulates, or fingerprints can affect performance.
• Do not attempt to recalibrate or adjust axial sensor electronics without the correct OEM diagnostic tools; consult service documentation or authorized technicians.
• After replacement, perform rotor balancing and vibration checks per OEM limits before returning the pump to service.

Troubleshooting tips:

• No axial feedback signal — verify cable/connectors, inspect for bent pins, and confirm power to the sensor electronics.
• Intermittent readings — check for loose mountings, foreign particles, or damaged connector shielding that can introduce noise.
• Elevated vibration after replacement — re-check axial alignment and confirm the rotor was handled without disturbing balancing adjustments.

Ordering and support: order under the designation AXIAL SENSOR UNIT ASSY V2304 for direct fitment to TMP-V2304 series pumps.

Storage and handling: store in a dry, static-controlled environment away from magnetic fields. Avoid mechanical shocks and prolonged exposure to corrosive atmospheres. If a protective shipping package is supplied, retain it for temporary storage or return shipments.

If you need technical drawings, cross-reference information, or on-site support for installation, please contact the parts supplier or your Shimadzu-authorized service provider with your pump serial number and service history to ensure correct selection and fitment.
