Red Dot Corp., a leader in climate control systems for heavy-duty vehicles, has introduced a sealed, microprocessor-controlled rotary actuator for 12V and 24V mobile HVAC applications.
Designed for commercial trucks, military vehicles and off-highway equipment used in construction, agriculture and other demanding environments, Red Dot’s actuator is ideal for managing air-distribution doors, water valves, and other functions where durability and precise, electronically controlled actuation are required.
Its microprocessor control is designed to maintain a constant torque across the range of operating voltage and automatically reduce torque in a stalled condition. “This level of precision means less stress on components and the potential for longer service life,” said Gary Hansen, vice president, Red Dot.
The actuator is sealed to IP68 standards (+/- 5 psi internal or external pressure) to resist moisture and other contaminants. Also, its dual-voltage capability allows it to be used in 12V or 24V applications, providing versatility from a single part number.
Additionally, the Red Dot actuator offers these benefits:
- Adjustable using linear voltage (potentiometer) or pulse-width modulated (PWM) signals.
- Meets the highest flame retardant specifications: UL 94-V0 and UL 94-5VA standards.
- Maximum torque: 13 in./lbs.
- Vibration tested to 9.8Gs.
- Rotation angle: 104 degrees standard.
- Rated for 300,000 cycles.
- Rated for operation between -40° and 185°F (-40° to 85°C)
- Diagnostic position feedback.
- Customizable functionality available.
- Reverse-polarity protected.
- 24V load-dump protected.
