Product Details

Flexible Thin Film Pressure Sensor SF45-65 Quick Response Better Sensor Better Life

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this state, the sensor output resistance can still respond to pressure changes, and the corresponding relationship is no longer applicable to the reference data sheet;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.
