• MD30-60 series flexible 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this state, the sensor output resistance can still respond to pressure changes, and the corresponding relationship is no longer applicable to the reference data sheet;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;
• After the sensor is stressed and maintains the pressure, the output resistance value will drift slightly over time, usually within 5%. This error can be reduced by the method of timing calibration. In the calibration operation, the waiting time after applying pressure is consistent with the waiting time in actual applications. Since the force state of the sensor is different in different application scenarios, it is recommended that the user arrange the sensor according to the actual application scenario and test the drift parameters by themselves.

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 weldedaccording 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.
