Loop Research LT210 – Laser Ride Height Sensor 0-40" with Track Temperature Sensor

The LT210 is a combination time of flight distance measurement sensor and track temperature sensor. It is ideally suited for ride height measurement applications where getting the most data is paramount. Available distance measurement ranges of 0-40” mean that even large wheel stands, or jumps can be accurately measured. High ambient light immunity means that even measuring in direct sunlight is not an issue. Track temperatures of 32-212ºF (0-100ºC) are measured with a separate sensor mounted on the bottom of the LT210 enclosure. Using the same M12 connector as the LT110, the LT210 can be powered with 5-36V and provides a 0-5V outputs to interface with the vehicle ECU or data logger.

Notes:

• Distance output is linear 0-5V to 0-39.4inches (0-100cm). At 4.8V (37.8inches) unit will clip output.
• Temperature output is linear 0-5V to 32-212F (0-100C).
• If unit is unable to detect a distance signal from out of range, or unable to detect surface, the distance output will go to 5V.
• If unit is unable to detect a highly reflective surface, it may be beneficial to angle the unit slightly relative to the surface, rather than perpendicular.
• Distance sensor lens material is acrylic. Do not use acetone, brake cleaner, etc. to clean as this will damage the lens and affect sensor performance. Clean distance sensor and temperature sensor lenses with microfiber or other soft cloth to keep dirt and debris from affecting performance.
• Distance sensor has blind zone of approximately 4 Inches. This means that objects closer than this cannot be measured accurately.
• Temperature sensor has a field of view of approximately 12deg.
• It is recommended to mount sensor with logo on the sensor mounted fore-aft. i.e. Logo on sensor body pointed forward or backward on the car.
• Removable thread locking compound on the mounting hardware is generally a good idea, especially in high vibration environments.
• Connector pinout as shown (as viewed from top of sensor):
