The 977 000 series electronic hand throttle is a rugged, high-performance remote throttle control unit built for extreme conditions. Designed for use with electronic engines, it serves as a primary or secondary operator control for modulating engine RPM. The unit is housed in a durable enclosure, rated IP69K for complete protection against water and dust ingress, even under high-pressure washdowns. It is designed to operate reliably in extreme temperatures, from -40°C to +85°C. This hand throttle is a versatile solution for original equipment manufacturers (OEMs) and system integrators across various sectors, including construction, agriculture, and material handling.

Key Features

Engineered for harsh operating conditions, the 977 000 series combines rugged mechanical construction with advanced electronic programmability to deliver reliable, fail-safe throttle control.

IP69K Rated for Ultimate Environmental Protection: The 977 000 series offers an ingress protection rating of IP69K, ensuring total resistance against dust and high-pressure, high-temperature water jets. This makes it perfectly suited for outdoor applications and environments that require rigorous steam cleaning, safeguarding the internal electronics from damage.
Engineered for Extreme Temperature Ranges: Built to perform where other components fail. The hand throttle operates flawlessly in ambient temperatures ranging from -40°C to +85°C and can be stored safely between -40°C and +125°C, ensuring reliable engine speed control in arctic cold or scorching heat.
Programmable Output Signal for Seamless Integration: The output signal is factory-programmable to match your specific control system architecture. Whether you need a simple analogue signal, a digital PWM (Pulse Width Modulation), an Idle Validation Switch (IVS), a current-based signal, or advanced CAN protocols (J1939 or CANopen), the 977 000 can be configured to interface directly with your engine ECU or vehicle management system.
Compliance with Global Safety and Industry Standards: Safety and reliability are paramount. This throttle control complies with a comprehensive list of international standards, including FMVSS 124 for throttle returnability, FMVSS 302 and ECE R118 for flame resistance, ECE R10.06 for electromagnetic compatibility, and ISO 26262 part 5 for functional safety up to ASIL C (for specific sensor variants).
Optimized 60-Degree Travel Angle for Precise Modulation: The throttle features a smooth, progressive 60° travel angle, providing the operator with excellent tactile feedback and fine control over engine RPM. This ergonomic design reduces operator fatigue and allows for precise speed adjustments in critical applications.
Customizable Actuation Force and Connection Options: The 977 000 series offers optional customizable actuating force, allowing you to tailor the lever's resistance to operator preference or specific functional requirements. Additionally, optional connector kits or custom wire harnesses simplify installation and ensure a perfect fit with your existing electrical systems.

Applications

Construction & Earthmoving Equipment: Provides reliable throttle control for heavy machinery such as excavators, wheel loaders, graders, and dozers, enabling operators to maintain consistent engine power while managing other hydraulic functions.
Agricultural Machinery: Ideal for tractors, combine harvesters, and large sprayers, allowing for the setting and maintaining of a constant engine speed for power take-off (PTO)-driven implements or field operations.
Mining & Material Handling: A robust solution for drilling rigs, haul trucks, cranes, and forklifts, where high vibration, dust, and the need for fail-safe engine control are critical for safety and productivity in harsh underground or open-pit environments.
Specialty & Municipal Vehicles: Perfect for firefighting apparatus, emergency response units, airport ground support equipment (tugs), and municipal sweepers, providing a secondary station for controlling auxiliary engines or pumps.
Marine & Off-Road Equipment: Suited for workboats, barges, and heavy-duty utility vehicles (UTVs), delivering corrosion-resistant and water-proof throttle control for propulsion or for managing deck machinery in high-moisture marine environments.
Industrial Stationary Engines: An excellent choice for controlling the engine speed of generator sets (gensets), air compressors, hydraulic power units, and irrigation pumps, allowing for remote RPM adjustment from a control panel.
