Vemo V10-72-0950 Sender Unit – Interior Temperature Sensor

The Vemo V10-72-0950 is a precision interior temperature sender unit designed to provide accurate cabin climate data for modern automotive electronic control systems. It is engineered to integrate seamlessly with the vehicle’s body control module (BCM) and climate control units, delivering reliable temperature readings that enable optimal HVAC performance.

Key Functional Characteristics

• Temperature Measurement Range: -40 °C to +125 °C – suitable for all climatic conditions encountered in automotive environments.
• Output Signal: 0–5 V analog voltage proportional to the measured temperature, compatible with standard vehicle sensor interfaces.
• Response Time: < 1 second from temperature change to signal output, ensuring real‑time cabin monitoring.
• Power Supply: 12 V DC (typical automotive battery voltage), with a low power consumption of < 0.5 W during operation.
• Mechanical Design: Compact rectangular housing, 30 mm × 20 mm × 10 mm, with a robust metal shell to withstand vibration and shock.

Electrical Specifications

Mechanical and Environmental Robustness

• Operating Temperature: -40 °C to +125 °C – covers extreme automotive climates.
• Humidity Resistance: Up to 95% RH (non‑condensing) – suitable for humid cabin environments.
• Shock and Vibration: Tested up to 15 g shock and 20 Hz vibration, ensuring durability in high‑performance vehicles.
• Ingress Protection: IP65 rating – protected against dust ingress and water jets.

Installation Guidelines

1. Location Selection: Mount the sensor in a spot where it can accurately reflect cabin air temperature, typically near the dashboard or HVAC vent, avoiding direct airflow from vents that could skew readings.
2. Connection: Use the supplied two‑wire harness. Connect the positive wire to the vehicle’s 12 V supply (often via a dedicated sensor power line) and the negative wire to the common ground.
3. Signal Routing: Route the signal cable away from high‑temperature components such as the engine bay or exhaust system to prevent thermal drift.
4. Secure Mounting: Fasten the unit with the provided mounting screws and ensure a snug fit to minimize vibration. Use anti‑vibration pads if necessary.
5. Calibration Check: After installation, verify that the sensor output matches the vehicle’s climate control display within ±1 °C. Adjust the BCM calibration settings if required.
