Hitachi 4436535 Low-Pressure Sensor (42CP2-4) – Genuine OEM for ZX200-3 / ZX210-3 / ZX230-3 / ZAX130 / ZAX330 Excavators

1. Key Features & Benefits

• Genuine Hitachi OEM low-pressure sensor – OEM part number 4436535 (cross‑reference 42CP2-4). Manufactured by Hitachi to original equipment specifications for the ZAX and ZX series excavators. This is a brand‑new, factory‑spec sensor – not an aftermarket substitute.

• Critical hydraulic system monitoring component – This low‑pressure sensor is installed on the main control valve (distribution valve) and swing motor circuit. It continuously monitors hydraulic pressure in the low‑pressure circuits, converting pressure readings into electrical signals that are sent to the machine’s controller. This enables precise, real‑time control of hydraulic functions.

• Robust construction for heavy‑duty applications – Housed in a durable casing with a hardened sealing surface, the sensor is designed to withstand the extreme vibration, temperature fluctuations, dust, moisture, and contamination common in mining, quarrying, and heavy construction environments.

• Fast response time – Provides timely and accurate feedback on pressure changes, ensuring smooth, responsive machine operation.

• Plug‑and‑play replacement – Direct bolt‑on replacement for the original Hitachi sensor. Fits the existing wiring harness with standard 3‑pin connectors – no modifications, no adapters.

• Wide compatibility across Hitachi Zaxis and EX series – Fits a broad range of Hitachi excavator models including ZX200-3, ZX210-3, ZX230-3, ZAX130, ZAX330, ZX120, ZX110, ZX70, ZX225, ZX240, ZX350, ZX470, ZX670, ZX870, as well as EX200-2, EX200-3, EX200-5, and EX1200-5 series.

• Pre‑shipment visual verification – Before packing, we send you detailed high‑resolution photographs of the actual sensor. You approve shipment – we never ship blind.

• Fast delivery – 3–7 working days lead time from our Guangzhou warehouse. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight.

3. Applications

The Hitachi 4436535 low‑pressure sensor is a critical monitoring component for ZX200-3, ZX210-3, ZX230-3, ZAX130, ZAX330, and compatible excavators used across a wide range of demanding job sites:

• Large‑scale construction & earthmoving – Highway excavation, dam building, bridge footings, and large‑scale earthmoving projects. The sensor provides real‑time low‑pressure feedback from the main control valve, ensuring smooth, predictable machine response – from delicate grading to heavy bucket loads.

• Urban construction & utilities – Sidewalk repairs, water and gas line trenching, and small‑scale demolition in tight urban spaces. The sensor‘s fast response time and precise pressure monitoring enable the “fine‑touch” control needed for working near existing structures.

• Quarrying & aggregates – Loading trucks, stockpile management, and material handling in granite, limestone, and basalt quarries. The sensor’s robust, sealed construction withstands the harsh, dusty environment, ensuring reliable pressure monitoring shift after shift.

• Mining support – Site cleanup, road maintenance, and drainage works. A genuine new sensor provides predictable performance and eliminates the risk of hydraulic control failure – avoiding costly unplanned downtime in remote mine sites.

• Equipment rental fleet – 20–30 ton excavators are high‑value rental assets. A genuine new low‑pressure sensor ensures reliable hydraulic control and eliminates the risk of sensor‑related breakdowns – avoiding costly mid‑rental failures and customer complaints.

4. FAQ – Frequently Asked Questions

Q1: Is this low‑pressure sensor an exact replacement for my Hitachi ZX200-3, ZX210-3, ZX230-3, ZAX130, or ZAX330?

A: Yes. The 4436535 (42CP2-4) is the genuine Hitachi low‑pressure sensor for these models and a wide range of compatible Zaxis and EX series excavators. To confirm compatibility for your specific machine, send us your machine serial number and a photo of the old sensor – we will verify within 2 hours.

Q2: Where is this sensor located on the machine?

A: The sensor is typically installed on the main control valve (distribution valve) and also monitors the swing motor circuit. It measures low hydraulic pressure in these circuits, providing critical data to the machine‘s control system.

Q3: What does the “42CP2‑4” cross‑reference mean?

A: “42CP2‑4” is an interchangeable part number for the same Hitachi low‑pressure sensor. Both 4436535 and 42CP2‑4 refer to the identical OEM sensor and can be used interchangeably.

Q4: Is this a new sensor or a remanufactured unit?

A: It is brand new / genuine original, not remanufactured. All internal components are new. The sensor is manufactured to Hitachi‘s original specifications and meets all OEM performance standards.

Q5: What are the physical specifications of this sensor?

A: The sensor has a thread diameter of approximately 13 mm, an overall length of 54 mm, and features a 3‑pin connector.

Q6: What is the warranty on this sensor?

A: The warranty period is 3 to 6 months depending on product details. We do not provide warranty service for genuine original parts. Our value is delivered up front: genuine Hitachi components, new‑condition sensor, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote aftermarket alternatives – ask our sales team.

Q7: How long does delivery take?

A: Delivery is 3–7 working days after order confirmation. Flexible shipping options including DHL, TNT, UPS, FedEx, and sea freight are available.

Q8: What payment methods do you accept?

A: We accept T/T (wire transfer), Western Union, and PayPal.

Q9: How can I verify the sensor is genuine before shipping?

A: Before packing, we send you clear, high‑resolution photographs of the actual unit – part number markings, connector, and overall condition. You approve shipment only after reviewing these images. We never ship blind.

Critical installation tip for the 4436535 low‑pressure sensor:
– Clean the mounting area – before removing the old sensor, thoroughly clean the mounting area to prevent contamination from entering the hydraulic system.
– Inspect the electrical connector – check the existing harness connector for corrosion or damaged pins. Replace the connector if necessary.
– Use thread sealant carefully – apply a small amount of thread sealant to the sensor threads, taking care not to block the pressure sensing port.
– Torque to specification – do not overtighten, as this can damage the sensor housing or the valve body.
– Test after installation – after installation, start the engine and verify that the machine‘s hydraulic system operates correctly and that no fault codes are present.

Warranty note: The warranty period is 3 to 6 months depending on product details. We do not provide warranty service for genuine original parts. Our value is delivered up front: genuine Hitachi components, new‑condition sensor, and pre‑shipment visual verification. For customers who require a warranty‑covered option, we can quote aftermarket alternatives – ask our sales team.

The low‑pressure sensor is the eyes of your Hitachi ZX200-3, ZX210-3, ZX230-3, ZAX130, or ZAX330‘s hydraulic control system. When it fails, your machine loses precise hydraulic control and responsiveness. A genuine new 4436535 from Hongtengda Parts restores accurate pressure monitoring and machine performance – not with unknown or reconditioned components, but with factory‑fresh Japanese engineering. Send us your machine serial number – we will confirm compatibility and provide a quote within 24 hours.
