VORGENS 12V Actuator With Feedback
The VORGENS 12V Linear Actuator provides a robust 2000 lbs dynamic thrust with an 8-inch stroke and IP65 protection. Its stainless steel shaft and metal gears deliver durable performance for heavy-duty operations. A built-in potentiometer enables positional feedback, allowing synchronized multi-actuator control and error compensation to extend service life. The unit also includes overload protection via a mechanical slip clutch, suitable for outdoor machinery and agricultural applications where exposure to dust and moisture is possible.
Progressive Automations PA-17-POT
The PA-17-POT is a heavy-duty 12V actuator with an 8-inch stroke, capable of 2000 lbs dynamic thrust and 4000 lbs static hold. Its stainless steel shaft and metal gears prioritize longevity in industrial settings. The actuator features an integrated potentiometer for precise position feedback, supporting synchronized control across multiple actuators. An IP65 rating provides protection against dust and water, and a mechanical slip clutch offers overload protection to safeguard equipment during peak loads.
Progressive Automations PA-04 (30 in)
The PA-04 family offers versatile 12V or 24V operation with a stroke range from 6” to 40” and a 400 lbs force rating. It features Hall effect feedback, IP66 water resistance, and broad use across automation, automotive, medical devices, and home projects. The design supports synchronized multi-actuator operations and is well-suited for outdoor setups such as gate openers, solar trackers, and equipment enclosures, where reliable feedback improves control accuracy.
Progressive Automations PA-04 (18 inch)
The 18-inch PA-04 variant keeps the same core advantages: 400 lbs force, IP66 protection, and Hall effect feedback. Its longer stroke makes it ideal for projects requiring more travel without sacrificing feedback accuracy. It is commonly used in outdoor automation, gate systems, and adjustable furniture, where steady, trackable motion is essential for performance and safety.
Progressive Automations PA-HD2 18 inch
The PA-HD2 is a heavy-duty 12V actuator designed for demanding industrial use, delivering up to 2023 lbs dynamic thrust and up to 2698 lbs holding force. It features IP67 protection for dust and water resistance and includes a mechanical slip clutch for overload protection. The Hall effect feedback enables precise positioning and synchronization across multiple units, making it suitable for manufacturing lines, agricultural equipment, and heavy lifting systems where reliability is critical.
Buying Guide: Key Purchase Considerations
When selecting a linear actuator with position feedback, consider the following factors to ensure you choose the best fit for your application:
- Load and stroke: Match the dynamic thrust and static holding force to your load, and choose a stroke length that meets your travel range needs without overextending components.
- Feedback technology: Potentiometer-based feedback is common and cost-effective, while Hall effect sensors offer higher reliability and resistance to wear in some environments. Decide based on accuracy requirements and environmental conditions.
- Protection rating: IP65/66/67 ratings indicate dust and water resistance. For outdoor or dusty environments, prioritize IP66 or IP67 to minimize maintenance and downtime.
- Duty cycle and protection: Consider overload protection like mechanical slip clutches, especially in applications with potential binding or jam conditions.
- Electrical compatibility: Verify voltage requirements (12V vs 24V) and control interfaces compatible with your system. Some models support synchronized multi-actuator operation for complex setups.
- Physical construction: Stainless steel shafts and metal gears improve durability in harsh environments. Look for corrosion resistance if exposure to moisture is expected.
- installation and dimensions: Check mounting options, bracket compatibility, and the overall footprint to ensure a straightforward integration.
- Cost of ownership: Factor in longevity, maintenance needs, and availability of replacement parts or feedback components when evaluating total cost of ownership.
In automated systems, the choice between potentiometer and Hall feedback can influence control strategy, especially in multi-actuator synchronization and precise stop positioning. For rugged outdoor use with heavy loads, models with IP67 protection and mechanical overload protection are typically preferred. For lighter-duty or indoor automation, IP65 with a potentiometer-based feedback may provide a balanced mix of cost and performance.
