Long-stroke Pin Puller
The long-stroke pin puller uses shape memory alloys as the trigger and a spring-driven mechanism for pin extraction. The pin is pulled out before use, and when powered, the pin contracts. It features a simple and reliable structure with low unlocking impact, making it an ideal replacement for pyrotechnic pin pullers.
Description
Key Features:
1. Low Power Consumption: Compatible with pyrotechnic ignition signals.
2. Fast Response: 50ms response time at 10A current at room temperature.
3. Good Environmental Adaptability: Not sensitive to temperature, humidity, vacuum, or static electricity.
4. Dual Shape Memory Alloy Drive: Dual-point and dual-line power supply with redundant mechanical and electrical designs.
5. Reusable: Can be repeatedly used and verified with high reliability.
6. Low Unlocking Impact.
7. Ease of Use: No special positions, tools, or operations required; screws are directly installed.
