Solenoid lock Ultra Compact Lock

electromechanicalfor doorcompact

Overview
The Ultra Compact Lock (UCL) is a compact, energy-efficient door locking solution using Shape Memory Alloy (SMA) actuation. It is designed for battery-powered, space-constrained applications where long battery life and minimal installation space are required.

Key benefits

• At least 50% lower power consumption compared with comparable electromechanical solutions.
• Very compact dimensions to maximize product-design freedom in battery-powered systems.
• European engineering and manufacturing for reliable supply and local support.
• Competitive global performance for demanding OEM applications.

Operating principle
The UCL uses an SMA wire that is activated by a short electrical pulse to release a spring-loaded locking bolt. The bolt re-engages automatically when the door closes, eliminating the need for continuous power and minimizing energy consumption while ensuring secure locking.

Applications and suitability

• Parcel lockers and package stations — secure access with extended battery life for 24/7 systems.
• Lockers and smart cabinets — compact form factor with holding forces suitable for heavy use.
• Hotel room doors — quiet, low-energy access for battery-driven door systems.
• Vending and self-service machines — space-saving integration with high security.
• Medical and laboratory devices — suitable for equipment exposed to high mechanical stress (optional shock resistance).

Why OEMs choose the Ultra Compact Lock

• Significantly reduced energy per unlock (short activation pulse only).
• Smaller installation envelope enabling more compact end products.
• Options for customization and local engineering support in Europe.
• Longer battery life and fewer maintenance interventions.

Technical highlights

• Very low power consumption; unlock requires only a short electrical pulse.
• Dimensions: 45 × 45 × 15 mm.
• Maximum static holding force: 5,000 N (until material failure).
• Optional shock resistance: up to 300 g (all axes).
• Service life: approx. 30,000 switching cycles.
• Includes door hook and emergency opener options.

Integration details
The UCL is ready-to-install and operates at a nominal 1.7 V DC. Example activation profile: peak up to 2 W for approx. 500 ms to unlock. Mechanical design includes two mounting holes Ø 4.1 mm for straightforward integration. Actual battery life depends on number of operations, battery chemistry, control electronics and ambient temperature.

Applications-specific performance notes

• Holding force up to 5,000 N supports high-security and load-bearing locking applications.
• Optional shock resistance up to 300 g makes the unit suitable for medical and laboratory equipment subject to high mechanical stress.
• Energy profile (1.7 V operation and pulse actuation) is optimized for battery-powered systems.
