Victor, NY - September 18, 2007 - New Scale Technologies, Inc.
today announced a new low-power actuator for next-generation electronic locks and latches.
The SQLM Series SQUIGGLE Motor Lock Module draws 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.

Applications
Traditional mechanical lock and key systems are rapidly being displaced by magnetic cards,
key panels and biometric sensors in many commercial applications. Electronic access systems
improve security, allow companies to monitor and flexibly control access to different areas,
and reduce total system cost. In addition to building and facility access, electronic locks
and latches are increasingly used for applications such as pharmaceutical cabinets and carts
in hospitals, safety interlocks in automotive applications, and protective interlocks on IT hardware.
Engineering samples are available now for qualified OEMs.
