LC52S00012P1 High Pressure Sensor for Kobelco SK200-6 SK230-6E SK200-8 SK250-8

LC52S00012P1 50MPa High Pressure Sensor for Kobelco Excavator

The LC52S00012P1 high pressure sensor is supplied for Kobelco excavator hydraulic pressure sensing system repair. It is commonly searched as a 50MPa pressure sensor, hydraulic pressure sensor or high pressure switch for Kobelco SK200-6, SK200-6E and related excavator model references.

This page focuses on LC52S00012P1 as the main part number. YY52S00033F1 can be used as a checking reference in some aftermarket listings, but final fitment should be confirmed by the old sensor number, pressure rating, connector plug, thread type, sensor body shape and machine information before ordering.

Part Number and Sensor Type Notes

LC52S00012P1 is the main part number direction for this product page. The pressure rating should remain clearly visible because buyers often search this part together with 50MPa hydraulic pressure sensor wording.

This product should be described as a high pressure sensor or hydraulic pressure sensor, not as a general oil pressure switch catalog page. Similar-looking sensors may differ in pressure range, connector type, thread size, electrical signal and installation position.

For SEO clarity, this page should not keep the old general pressure switch list with Komatsu, Hitachi and Caterpillar part numbers. Those items belong to separate product pages or a category guide, not inside the LC52S00012P1 product description.

Application Reference for Kobelco Excavators

The strongest application direction for this page is Kobelco SK200-6 and SK200-6E excavator hydraulic system repair. Market references may also mention SK200SR, SK210LC-6E, SK230-6E, SK250LC-6E, SK290LC-6E, SK330LC-6E and other Kobelco model references depending on machine version and sensor position.

These model names should be treated as application references, not as the only fitment proof. Kobelco excavators may use different sensors according to serial number, hydraulic circuit layout, controller configuration and previous repair history.

For accurate ordering, compare the old sensor label, connector plug, thread area, sensor body size and installation position before quotation.

How to Confirm the Correct LC52S00012P1 Sensor

Before ordering, compare the removed pressure sensor carefully. A wrong pressure range, plug type or thread style can cause installation failure or incorrect hydraulic pressure signal.

• Confirm whether the old sensor number is LC52S00012P1 or a listed checking reference.

• Check whether the required pressure rating is 50MPa.

• Compare the connector plug, pin layout and wiring direction.

• Check the thread type, thread length and sealing method.

• Compare the sensor body shape, hex size and installation position.

• Send machine model, serial number and old sensor photos before quotation if you are not sure.

Common Failure Symptoms

A hydraulic high pressure sensor may need replacement when the excavator shows abnormal pressure warning, unstable pressure signal, sensor fault code, incorrect hydraulic pressure reading, intermittent signal loss or hydraulic control problems related to pressure feedback.

These symptoms are not always caused by the sensor itself. Wiring harness damage, loose connector pins, oil contamination, poor ground, controller signal problems, real hydraulic pressure faults or damaged hydraulic components can create similar issues.

Before replacing the sensor, inspect both the electrical circuit and the hydraulic pressure condition. Replacing the sensor without checking the circuit may not solve the problem if the wiring or hydraulic system is the real cause.

Troubleshooting Before Replacement

Before ordering an LC52S00012P1 replacement sensor, check the related electrical and hydraulic system. This helps repair shops and equipment owners avoid replacing the wrong component.

• Inspect the connector for corrosion, looseness, oil contamination or broken pins.

• Check wiring harness continuity between the sensor and controller.

• Confirm whether the displayed pressure value matches the actual hydraulic pressure test.

• Check hydraulic oil cleanliness, filters and possible pressure fluctuation in the circuit.

• Inspect whether the sensor thread or sealing area is leaking.

• Confirm whether the fault follows the sensor after testing or comparison.

Installation and Maintenance Notes

Stop the machine and release hydraulic pressure before removing the old sensor. Clean the surrounding area to prevent dust, water or metal particles from entering the hydraulic circuit.

Before installation, compare the replacement sensor with the removed unit. Check connector type, thread style, sealing surface and sensor body shape. Do not force the connector if the plug shape or pin layout is different.

After installation, check for oil leakage, abnormal warning codes and pressure signal stability. Clean hydraulic oil and stable electrical connections help reduce repeated sensor failure.

Buying Notes for Repair Shops and Parts Distributors

For repair shops, this LC52S00012P1 50MPa pressure sensor is suitable for Kobelco excavator hydraulic pressure signal troubleshooting when the old sensor is damaged, leaking or unable to provide stable feedback. For distributors, it can be supplied as a small electrical hydraulic replacement part for Kobelco excavator service demand.

Topvelsun supports small repair orders and bulk inquiries. To improve quotation accuracy, please send the required quantity, old sensor number, machine model, serial number and photos of the connector, thread and installation position.

FAQ

What is the main product on this page?

This page is for the LC52S00012P1 50MPa high pressure sensor used for Kobelco excavator hydraulic pressure sensing system repair.

Can YY52S00033F1 be used as a reference?

YY52S00033F1 appears together with LC52S00012P1 in some aftermarket listings and can be used as a checking reference. Final fitment should still be confirmed by the old sensor, connector, thread and machine information.

Which Kobelco models are the main references?

The main model references are Kobelco SK200-6 and SK200-6E. Other Kobelco models may appear in aftermarket references, but the old sensor number and physical configuration should be checked before shipment.

Is this sensor always 50MPa?

This product page is positioned for the 50MPa LC52S00012P1 high pressure sensor. Please confirm the pressure rating on the old sensor or service information before ordering.

What should I check before ordering?

Please check the old sensor number, pressure rating, connector plug, pin layout, thread type, sensor body shape and machine serial number. Clear photos of the removed sensor are recommended.

What can cause repeated pressure sensor failure?

Repeated failure may be caused by oil contamination, damaged wiring, loose connector pins, poor ground, unstable controller signal, hydraulic pressure shock or installation of a sensor with the wrong pressure range.
