FG40 EPM is an electro-permanent magnet designed for aerospace and robotic applications. It combines the advantages of electro- and permanent magnets by being able to switch between the on-state and off-state on demand (like an electromagnet); while consuming zero power in either state (like a permanent magnet).
The device supports the following communication interfaces:
- Cyphal/CAN FD control with diagnostic telemetry;
- RCPWM control input;
- voltage level control input;

Variants
Three types of EPM are available:
- FG401M - optimized for cost-sensitive applications.
- FG401MA - nearly a drop-in replacement for OpenGrab EPM v3.
- FG402M - optimized for mission-critical applications.
