Vemo V38-72-0036 Sensor, wheel speed

Vemo V38-72-0036 Sensor – Wheel Speed

The Vemo V38-72-0036 is a high‑performance wheel speed sensor designed for modern automotive applications. It delivers precise rotational data to the vehicle’s electronic control unit (ECU), enabling reliable operation of critical systems such as Anti‑Lock Braking System (ABS), Traction Control, and Electronic Stability Program.

Key Functional Characteristics

• Signal Type: Hall effect sensor – generates a clean square wave proportional to wheel rotation.
• Operating Voltage: 12 V DC (typical automotive battery voltage).
• Output Frequency: Up to 20 kHz, allowing accurate speed measurement even at high vehicle velocities.
• Temperature Range: –40 °C to +125 °C, ensuring reliable performance in extreme climates.
• Mechanical Mounting: Standardized mounting flange compatible with most rear‑wheel assemblies on Nissan models such as Qashqai and Qashqai+2 I.

Design Features for Durability

The sensor’s housing is constructed from high‑strength, corrosion‑resistant alloy. It incorporates a sealed optical interface that protects the Hall element from dust, moisture, and road debris. The internal winding is shielded to minimize electromagnetic interference (EMI), which could otherwise corrupt speed signals.

Installation & Compatibility

The Vemo V38-72-0036 is engineered for seamless integration into existing vehicle architectures:

• Rear‑Wheel Mounting: Fits the standard sensor bay on the rear axle of Nissan vehicles, including Qashqai series.
• Electrical Interface: Direct plug‑and‑play connection to the ABS module; no additional adapters required.
• Calibration: Built‑in calibration constants allow the ECU to interpret sensor output without manual adjustment.

Performance in Safety Systems

By delivering accurate wheel speed data, the Vemo V38-72-0036 enables:

• ABS Operation: Rapid detection of wheel lock‑up and precise modulation of brake pressure.
• Traction Control: Identification of wheel slip to apply corrective braking or throttle reduction.
• Electronic Stability Program (ESP): Real‑time monitoring of individual wheel speeds for yaw control.

Quality Assurance & Standards Compliance

The sensor undergoes rigorous testing against automotive industry standards, including:

• ISO 26262 Functional Safety: Ensures the component meets safety integrity levels required for critical vehicle functions.
• EN 50125-1 (Railway) & ISO 9001: Demonstrates adherence to quality management and reliability benchmarks.

Applications Beyond Nissan
