The Electronic Rotary Control 978 000 series converts mechanical rotary input into a proportional electronic signal that communicates with an engine control module (ECM), vehicle control unit (VCU), or programmable logic controller (PLC). When the operator rotates the control knob, an internal non-contact sensor detects the angular position and generates an output signal corresponding to the rotation angle. This signal is factory-programmed to match the target system’s input requirements — whether analogue voltage, PWM duty cycle, IVS switching, current loop, or CAN-based protocol (J1939 or CANopen). The ECM interprets this signal and adjusts engine speed, actuator position, or other controlled parameters accordingly. The device’s IP69K-rated sealed housing and rugged internal construction ensure reliable operation even under high-pressure washdown, extreme temperatures, and continuous vibration. For safety-critical installations, select models (APS Dual 5V and APS CAN) incorporate ISO 26262 ASIL C design principles, providing redundant monitoring and fault detection to meet stringent functional safety requirements for throttle-by-wire applications.
An electronic rotary control converts mechanical rotary input into an electrical signal to control engine speed, throttle position, actuators, or other electronic systems. The 978 000 series is commonly used in off-highway machinery, agricultural equipment, marine systems, and industrial automation for throttle-by-wire and drive-by-wire applications.
The 978 000 series offers factory-programmable output signal types including Analogue, PWM (Pulse Width Modulation), IVS (Idle Validation Switch), Current, CAN J1939, and CANopen. Outputs are configured at the factory according to customer specifications to ensure seamless integration with your engine control system.
The 978 000 series is rated IP69K for water and dust ingress protection. This means it is fully protected against dust ingress and can withstand high-pressure, high-temperature water jet washdowns, making it suitable for outdoor and harsh industrial environments such as agriculture, mining, and marine applications.
The electronic rotary control 978 000 series operates reliably from -40°C to +85°C and can be stored from -40°C to +125°C, ensuring consistent performance in extreme cold and high-temperature environments such as arctic mining operations or desert construction sites.
The 978 000 series complies with FMVSS 124 (throttle control return), FMVSS 302 / ECE R118 (flame resistance), 72/245/EEC and ECE R10.06 (electromagnetic compatibility). Select models (APS Dual 5V and APS CAN) are developed to ISO 26262 Part 5 ASIL C as a Safety Element out of Context (SEooC) for functional safety applications.
The 978 000 series offers extensive customisation including choice of control knobs, multiple mounting configurations, customisable actuation force, optional detent feeling for tactile feedback, connector kits or custom wire harnesses, and full support for CAN J1939 protocol.
Our engineers will confirm the correct Electronic Rotary Control 978 000 series configuration for your specific vehicle, equipment or automation requirements. Whether you need a standard unit with analogue output or a CAN J1939 variant with custom actuation force and detent, we provide full technical documentation and a competitive quote tailored to your operational environment.
