New Scale Technology Offers New Low-Power Actuator In Small Package For Electronic Locks & Latches

New Scale Technologies, Inc. announced a new low-power actuator for next-generation electronic locks and latches. The SQLM Series SQUIGGLE Motor Lock Module are said to draw far less power than solenoids or stepper motors and uses only half the space. It is designed to drop into existing lock or latch assemblies, allowing lock manufacturers to reduce the size and power requirements of their electronic locks.

The SQLM-3.4-4 actuator assembly contains a patented piezoelectric SQUIGGLE™ motor with optical limit switches in compact polymer housing (approximately 6 x 6 x 17 mm). In a typical lock application, the tip of the SQUIGGLE motor screw is used to push a spring-loaded shear pin, which engages the latching mechanism. The SQUIGGLE motor provides four millimeters of stroke with high force and speed, and holds its position with power off.

A complete SQLM lock module includes the actuator and an MC-4012-3.4 driver card, powered by two AA batteries and controlled using TTL control signals. The 33 x 38 x 10 mm card is ready for installation next to the lock microprocessor and power source, or can be used as a reference design for ASIC implementation.

Engineering samples are available now for qualified OEMs.
