SF45-65 flexible thin film pressure sensor
Description
SF45-65 flexible thin film pressure sensor is a new type of sensor
which is using flexible pressure sensing technology with
independent intellectual property rights. It is printed on flexible
and thin materials with strong adhesion, bending resistance, and
high sensitivity flexible nano-functional materials., So that it
can achieve high-sensitivity detection of pressure.
SF45-65 flexible film pressure sensor is a resistive sensor. The
output resistance decreases as the pressure applied to the surface
of the sensor increases. The pressure can be measured through a
specific pressure-resistance relationship.
The SF45-65 flexible film pressure sensor is a pressure sensor with
a square sensitive area. The sensitive area has a size of 46*46mm
and can measure pressure within 5kg. It is suitable for pressure
measurement scenarios on flexible surfaces, and can be widely used
in smart home, consumer electronics, automotive electronics,
medical equipment, industrial control, smart robots and other
fields.

Reference Circuit
Instructions
SF45-65flexible thin film pressure sensor is a non-polar component,
there is no directionality in the circuit；
- When using, please place the pressure sensitive zone of the sensor
on a firm, flat surface. Using the sensor on a curved or irregular
surface will make the sensor initially conductive, that is, in a
"response" state when there is no pressure; in this state, the
sensor output resistance can still respond to pressure changes, and
the corresponding relationship is no longer applicable to the
reference data sheet;
- If the supporting surface and the force applying surface are both
rigid and hard surfaces, and the contact surface is larger than the
sensitive area of the sensor, due to the sensor's own structure,
the pressure response may be small and unstable. A round soft
rubber pad needs to be affixed to the center of the sensitive area,
the diameter is slightly smaller than the sensitive area, and the
area should be greater than 60% of the area of the sensitive area;
- You can use double-sided tape to fix the sensor on the supporting
surface. Pay attention that the supporting surface is tidy and
clean before pasting. It is recommended to use 3M brand
double-sided tape; provide customized services;
Announcements
- When using the sensor, try to make the load received evenly and
avoid direct contact with the sensor by sharp objects;
- Over-range use will reduce the performance of the sensor or even
destroy the sensor;
- The sensor terminal is made of copper and tin-plated material, and
the lead can be welded according to the needs. It should be noted
that the soldering temperature should not be too high, it is
recommended that it should not exceed 300°C, and the contact time
should not exceed 1 second, so as to prevent the high temperature
from melting and deforming the film substrate.
