Bistable Rotary Solenoids

Bistable Rotary Solenoids can be driven to rotate in either direction and hold in either end position with no power applied. Only a short power pulse is required to stimulate movement.

Bistable Rotary Solenoid Technical Overview

Bistable Rotary Solenoids

Bistable Rotary Solenoids are especially well suited to paper transportation and sorting systems: for example, ATM machines and other banknote sorting mechanisms. These versatile rotary solenoids can be driven in either direction and hold in either end position with no current applied.

Bistable Rotary Solenoids offer a torque of up to 0.4Nm as well as an angle of up to +/-55°. Ball bearings ensure a high life expectancy while eliminating axial movement.

Characteristics of Bistable Rotary Solenoids:

• Rotary angle up to +/-55° around center position
• Torque up to 0.4Nm
• High life expectancy due to ball bearings
• No axial travel
• Fast response: Cycle times <5ms possible
• No integral mechanical endstops (must be supplied either in the customer mechanics or as a custom option)
• Options: Viscous damping with ferro-fluids: smooth operation, soft mechanical endstop, less noise
