7.51400 DT Temperature sensor

This DT Temperature Sensor and Switch is designed for use in the engine compartment of various vehicles. It offers technical benefits such as accurate temperature measurement up to 107°C, allowing for precise control over engine performance. Additionally, its compact size (62.0 x 32.0 x 32.0 mm) makes it easy to install and integrate into existing systems. Dimensions are provided by the supplier and may include packaging dimensions. Temperature sensors monitor the thermal state of various vehicle systems, including engine coolant, intake air, oil, and exhaust gases. These sensors are typically constructed with a thermistor or semiconductor junction, producing a voltage or resistance output inversely proportional to temperature. Data is transmitted to the Engine Control Unit (ECU), enabling adjustments to fuel delivery, ignition timing, and cooling fan operation. Common mounting locations include cylinder heads, intake manifolds, and within oil pans. Sensor accuracy and durability are critical for optimal engine performance and emissions control, with specifications varying by application and manufacturer. Modern sensors increasingly utilize digital communication protocols for enhanced data transmission and diagnostics.
