The 971 000 series electronic throttle position sensor is a high-performance sensing solution designed for electronic throttle control systems in demanding mobile and industrial applications. This potentiometric rotary position sensor converts mechanical throttle motion into electrical signals that engine control modules use to manage fuel delivery and engine speed. Built with a single return spring mechanism, the sensor ensures controlled motion and fail-safe operation. It is commonly deployed in heavy construction equipment, agricultural machinery, marine vessels, and commercial vehicles where reliable throttle position feedback is critical. The sensor supports multiple communication protocols and can be customized for specific actuation angles and lever configurations, making it suitable for OEM installations as well as retrofit projects.

The 971 000 series combines rugged environmental sealing with flexible electronics, delivering reliable throttle position feedback across heavy-duty industrial and mobile applications.

  • Factory-Programmable Output Configuration: The 971 000 series allows engineers to select from multiple output signals including analogue voltage, PWM, IVS, current loop, CAN J1939, and CANopen. This flexibility ensures seamless integration with various engine control units and vehicle management systems without requiring additional signal conditioning hardware.
  • IP69K Environmental Protection: With an IP69K ingress protection rating, this throttle position sensor withstands high-pressure water jets, steam cleaning, and complete dust immersion. This makes it particularly suitable for agricultural equipment, mining machinery, and marine applications where exposure to harsh washdown conditions is routine.
  • Wide Operating Temperature Range: The sensor performs reliably from -40°C to +85°C during operation and can be stored at temperatures from -40°C to +125°C. This thermal resilience ensures consistent throttle position measurement in arctic cold, desert heat, and high-temperature engine compartment environments.
  • Integrated Return Spring Mechanism: The built-in single return spring provides controlled mechanical motion and simplifies system integration. This feature enhances safety by ensuring the throttle returns to idle position when actuating force is removed, a critical requirement for industrial vehicle compliance.
  • ASIL C Functional Safety Compliance: The APS Dual 5V and APS CAN variants of this sensor meet ISO 26262 Part 5 requirements and are certified ASIL C (Safety Element out of Context). This makes the sensor suitable for safety-critical drive-by-wire applications where fault detection and system integrity are paramount.
  • AMP 6-Pin Connector Interface: The sensor features a standard AMP 6-pin connector that provides secure, vibration-resistant electrical connections. This industry-standard interface simplifies wiring harness integration and ensures reliable signal transmission in high-vibration environments typical of off-road vehicles and industrial equipment.
  • Heavy Construction Equipment: Excavators, wheel loaders, bulldozers, and motor graders rely on electronic throttle control systems for precise engine speed management. This sensor withstands the vibration, dust, and extreme temperatures found on construction sites.
  • Agricultural Machinery: Tractors, combine harvesters, sprayers, and forage harvesters operate in dusty, muddy conditions requiring sealed electronics. The IP69K-rated sensor withstands field conditions and pressure washing, ensuring reliable throttle feedback during critical planting and harvesting seasons.
  • Off-Highway Vehicles: Dump trucks, articulated haulers, and underground mining vehicles require rugged throttle controls that function in high-vibration, high-dust environments. The sensor's wide temperature tolerance and sealed construction ensure consistent performance in these demanding applications.
  • Marine and Workboats: Tugboats, barges, and commercial vessels expose electronic components to saltwater spray and humidity. The sealed housing and corrosion-resistant design maintain throttle position accuracy in marine environments where equipment reliability is essential for safe vessel operation.
  • Commercial Vehicles and Buses: Transit buses, delivery trucks, and specialty commercial vehicles benefit from the sensor's CAN J1939 output option for seamless integration with existing vehicle networks, enabling smooth accelerator response and compatibility with fleet management systems.
  • Material Handling Equipment: Forklifts, reach stackers, and container handlers require precise throttle control for safe load handling. The sensor's programmable output signals allow customization to match specific equipment control architectures.
  • Motorsport and Performance Vehicles: Rally cars, off-road race vehicles, and high-performance machinery demand throttle sensors with fast response and vibration resistance. The 971 000 series delivers reliable position feedback under extreme acceleration and shock loads.

How the 971 000 Series Electronic Throttle Position Sensor Works

The 971 000 series electronic throttle position sensor operates on a potentiometric principle to measure the angular position of a throttle linkage or pedal. When the operator actuates the throttle, the sensor shaft rotates proportionally to the input force. This rotation varies the resistance across the sensor's internal electrical element, generating a voltage signal proportional to the throttle angle.

This signal is transmitted to the engine control module, which interprets the voltage level and calculates the desired engine speed. The ECU then adjusts fuel delivery and air intake to achieve the requested throttle position. The integrated return spring automatically returns the sensor to the idle position when actuation force is removed, ensuring fail-safe operation.

For CAN-equipped variants, the sensor converts analog position data directly into digital CAN J1939 or CANopen messages, enabling direct communication with modern vehicle networks without analog-to-digital conversion at the ECU level. This reduces wiring complexity and eliminates signal drift common in long analog runs.
