This Product Selection Guide contains information to help select products in the Shock Sensors category on DigiKey.com
Shock Sensors are designed to detect and respond to the presence of a sudden change in acceleration, most often using piezoelectric principles. The characteristics are sensor type, sensing range, sensitivity, and mounting type. The sensor types are ball and vibration (Piezo film) with a sensing range of 0 to 1500 G, and sensitivities of 0.055 pC/G, 0.09 pC/G, 0.350 pC/G, 0.608 pC/G, 0.840 pC/G, or 1 mV/G.
SelectionCharacteristics
Sensor Type: Method by which the sensor measures its data.
Sensing Range: Indicates the range(s) of a physical input quantity over which a device is capable of producing a valid measurement.
Sensitivity: Typically, this would indicate the change in output corresponding to a set change in input. For example, a device with a sensitivity of .608pC/G, the output will change by .608 pico Coulombs for every change of 1G in input.
Output Type: Indicates the type of electrical signal the device provides, such as voltage.
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.
Package / Case: Indicates the type of protective case used on an electronic component to allow easy handling, installation, and protection. This selection was determined to be the closest industry standard applicable to the supplier device packaging. Typically it is best to check the actual dimensions from the datasheet rather than depend on this terminology when designing your circuit.
Mounting Type: Indicates how the device is attached.
Termination: Selection of termination style used to connect the device to a system.
