Pressure Switch 811W25503-0244 Sinotruk Sitrak

Product Introduction

This Pressure Switch 811W25503-0244 is an OEM pressure monitoring component for Sinotruk heavy-duty trucks (e.g., HOWO T7H, SITRAK C7H/G7S, HOWO TX7). It features a robust brass threaded body for direct installation into the vehicle’s pneumatic or hydraulic system, a precision mechanical contact mechanism, and a sealed black plastic electrical connector. Manufactured to strict quality standards, it provides reliable pressure detection and switching in high-vibration, high-pressure operating environments.

Core Functions

1. Pressure Detection & Switching: Monitors the pressure of vehicle systems (e.g., air brake system, hydraulic system) and triggers an electrical signal when the pressure reaches a predefined threshold, acting as a safety or control switch.

2. System Protection: Integrates with the vehicle’s control system to activate warning lights or protective measures if pressure levels fall outside the safe operating range, preventing system damage or failure.

3. Durable & Sealed Design: The brass body and sealed connector provide excellent resistance to pressure, vibration, and corrosion, ensuring a long service life in harsh operating conditions.

4. Precision Actuation: The precision-engineered internal mechanism ensures accurate and consistent pressure threshold actuation, preventing false triggers or missed signals.

5. OEM Compatibility: Features factory-matched threads and connector pinouts for plug-and-play installation, fully compatible with the original vehicle’s pneumatic/hydraulic and electrical systems, eliminating the need for calibration or modification.
