Active Latch Overview

---

The Active Latch is an electro-mechanical release module, driven by a piezo-ceramic actuator, designed and made to normal manufacturing tolerances. It is available in two formats

AL1 - Power to Block
AL2 - Power to Unblock

Features

• Our Design Guides (see Downloads) illustrate how the Latch may be deployed.
• Low power permits operation via network wiring, small batteries and even solar cells.

Benefits

• Low power consumption - Active Latch typically requires down to 25mJ per operation, significantly lower than typical solenoid or motor mechanisms. It also operates for a longer period without high inrush or stall currents; see the effect on our Power Calculator.
• Networked control - Active Latches low power makes them ideal for networked and/or digital applications.
• Virtually silent to operate.
• Speed less than 100mS operating time, for responsive control.
• Integrated electronics in the AL1a, requiring only a simple dc control voltage to operate. The wide operating voltage range (3.6 - 6.8V) ensures long battery life and reliable operation from digital systems.
• The compact size fits into door leaf and standard hole sizes, ideally suited for lockers and cabinets.
