Car seat sensors must be foolproof
As a very important part of automobile safety system, seat belt is closely related to seat occupancy sensor.When a passenger seat on, the sensor will be activated and connect to ECU,if the seat belt is not locked, the alarm from car speaker will remind the passenger to fasten the safe belt .FSRTEK has all kinds of seat sensors available in various shapes and sizes for customer to choose.At the same time, FSRTEK has rich experience in project development,able to design and customize the seat sensor for the specified seat.
FSRTEK design and production of seat sensors fully consider the requirements of the vehicle in different environments, all the sensor need to pass strict test before put into production,the tests include the high and low temperature test, trigger force test, product life test, voltage resistance test, waterproof test and a series of safety tests, to ensure the stability of the product performance.A qualified car seat sensor must be foolproof!
Seat sensor has more and more application now!
Now the seat sensor are not only used in the car seat belt alarm system, it can also be used in restaurants, library seat occupy statistics system, hospital patients in the bed or not identification system.

| 1. Select sensors that fit the shape and size of the seat.Please note that the contact point of the sensor cannot be placed in the seat groove(See chart 1), otherwise the sensitivity and performance will be affected. |
Chart 1
Chart 2
| 2. Select the sensor suitable for the seat size, too big sensor cannot be installed, too small sensor will have a blind area. |
| 3. The thickness and hardness of the sponge above the sensor have a great influence on the sensitivity of the sensor(See Chart 2).The best thickness of sponge is suitable for 2-3cm. The sponge should be medium hardness.The hardness of the surface under the sensor also has a great influence on the sensitivity of the sensor.The best trigger force and sensitivity can be achieved by adjusting the thickness and hardness of the sponge. |
Projects Using Seat Sensors
Custom Your Own MEMBRANE FORCE SENSORS!
We accept orders for custom seat sensors. If you need to customize production of seat sensors according to your needs, please let us know the information as below:
working size and shape
Tell us your demand size and shape of seat sensor, we can quickly complete the Preliminary confirmation.
lead length
Since seat sensor‘lead have no standard for length and materials , you need to provide the lead specifications in your mind.
connector type
We have six standard connector type for you to choose from.
trigger weight
The sensing area,force measure range,thickness and force repeatable of products you need.
Application
Tell us your application, our engineers can confirm your choice will be the best one, and give more suggestions to meet your budget.
FSRTEK 8 dimensional custom system
1. Shape customization
Any shape and irregular graphics can be made according to customer requirements (such as car seat size, seat position requirements). The high-precision laser machine can quickly complete the prototype confirmation.
2. Size customization
According to customer’s size specifications, professional tailor-made, the maximum size can be 1200*800mm.
3. Thickness customization
We can customize various AWG specification wires according to your requirements, non-UL and UL standards; the printed circuit can be as thin as 0.25mm.
4. Process customization
According to the customer’s drawing requirements or actual needs, select the appropriate process, such as insulation treatment, scratch-resistant treatment, and waterproof treatment .
5. Material customization
Provide suitable material selection, anti-scratch, anti-oxidation, frosting thickness, material softness and hardness. Commonly used materials such as American Kotutai PET, PVC, DuPont PET, American, Japanese and Korean silver paste.
6. Waterproof customization
According to customer requirements, custom IP65~IP67 standard waterproof requirements.
7. Flame retardant customization
Meet various flame retardant standards such as HB, V-2, V-1, V-0 and other high standards for automobiles.
8. Sensitivity customization
In response to the customer’s requirements for the size of the pressure, as well as the requirements of the installation location and installation method. We customize suitable sensitivity for customers to meet customer needs.
