This Product Selection Guide contains information to help select products in the Force Sensors category on DigiKey.com
Force Sensors detect and respond to the presence or a change in the amount of pressure on their actuator, which can be a ball, button, diaphragm, flat membrane, plunger, or pushbutton. The three sensor types are force sensing resistor, load cell, and resistive. Their operating force ranges covering 0 to 1500 newtons (N), 0 to 22,680 kilograms force (kgf) or 0 to 50,000 pounds (lbs.), with output options of analog voltage, resistive, ratiometric, and voltage.
SelectionCharacteristics
Specifications to determine which force sensor is right for your application.
Operating Force: Describes the maximum force or force range over which a device is able to provide a valid measurement.
Output: Indicates the type of electrical signal the device provides, such as analog, digital, voltage, etc.
Sensor Type: Identifies the type of force sensor, such as load cell or resistive.
Accuracy: Typically listed as +/- and a percentage this is the maximum amount of variation in the force reading from the actual force that may exist.
Compensated Temperature: The temperature range over which the sensor will provide a valid measurement for an input of force, within manufacturer specified performance limits.
Voltage - Supply: Typically represented by a range, this indicates the low and high voltage limits which one can expect standard operation. Voltages outside this range may damage the device and other system components.
Actuator Type: The type of actuator used to measure the load, such as a switch or diaphragm.
Actuator Style/Size: Form factor of the device’s mechanical interface.
Includes: Everything included with the purchase of the product.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
