Frequently Asked Questions

Continuous duty ratings indicate the force a solenoid can maintain indefinitely without overheating. Intermittent duty ratings show peak force for short activation periods (typically 10% duty cycle or less).

Continuous duty ratings indicate the force a solenoid can maintain indefinitely without overheating. Intermittent duty ratings show peak force for short activation periods (typically 10% duty cycle or less).

Absolutely. Our engineering team provides detailed FEA modeling and custom force-stroke curves for all applications, ensuring optimal performance for your specific requirements.

Standard prototypes ship in 2-3 weeks. Custom prototypes require 4-6 weeks. Production quantities depend on volume but typically 6-12 weeks for quantities over 100 units.

Yes, we offer biocompatible materials, low-outgassing components, and can provide material certifications for medical device applications. USP Class VI materials available upon request.
