Locking solenoid Bistable Locking Solenoid

compactbistable

The Kendrion bistable locking solenoid LLB is a compact, energy-efficient locking unit designed for safe and smart locking applications, with options for battery operation, position monitoring (Hall sensor) and manual emergency unlocking.

Key highlights

• Battery operation possible — suitable for mobile applications such as locking toolboxes or hospital side tables
• Energy-saving operating principle: only a short current pulse required for locking; permanent magnetic hold when de-energised
• Optional Hall sensor for end-position detection (minus switching, 5–30 V, max. 30 mA)
• Optional manual emergency unlocking

Benefits

• Very low energy consumption (suitable for battery use)
• Compact, cost-efficient design for space-constrained installations
• Simple integration with position monitoring and emergency release options
