Shock Sensors - PKGS-00LDP1-R
The shock sensor, PKGS series, is acceleration
sensor with 2 terminals and detects acceleration &
shock to be applied from outside,
as electrical signal.
By bimorph piezo elements clamped at the one-end
(Cantilever construction) with original polarisation
technology, the shock sensor has high sensitivity
and excellent durability.
The shock sensor is reflow solderable SMD type.
The shock sensor can have inclined primary axis
so that appropriate shock sensor can be chosen
for shock detection in HDD (Hard Disk Drive) and
optical pick-up control in optical drive &
optical-magnetic Drive.
Features
1. Small size, low profile, high sensitivity
and excellent durability.
2. Excellent linearity
3. High resonant frequency and wide bandwidth
4. Available tape and reel packaging
5. Reflowable
Application
1. HDD data writing protection, while shock is
applied from outside.
2. Shock detection and protection in DVD, CD-R,
CD-RW etc.
3. Pick-up control for disk type storage
in Digital camera, Camcorder etc.
4. Other applications requiring acceleration
detection.

Reflow Chart
1. Sensor output is defined by generated electrical charge. Please use this shock sensor with a non
inverting voltage amplifier circuit.
2. Please do not apply DC voltage for this shock sensor.
3. Please contact Willow Technologies for washing conditions.
