The FSG Series Force Sensor provides precise, reliable force sensing performance in a compact commercial-grade package. The sensor features a proven sensing technology that utilizes a specialized piezoresistive micro-machined silicon sensing element. The low power, unamplified, noncompensated Wheatstone bridge circuit design provides inherently stable mV outputs over the 5 N, 10 N, 15 N and 20 N force ranges.
Force sensors operate on the principle that the resistance of silicon-implanted piezoresistors will increase when the resistors flex under any applied force. The sensor concentrates force from the application, through the stainless steel plunger, directly to the silicon-sensing element. The amount of resistance changes in proportion to the amount of force being applied. This change in circuit resistance results in a corresponding mV output level change.
The sensor package design incorporates patented modular construction. The use of innovative elastomeric technology and engineered molded plastics results in overforce capacities of up to three times the rated force.
The stainless steel plunger provides excellent mechanical stability and is adaptable to a variety of applications. Various electric interconnects can accept prewired connectors, printed circuit board mounting, and surface mounting. The unique sensor design also provides a variety of mounting options that include mounting brackets.

Notes:
1. All force-related specifications are established using dead weight or compliant force.
2. The range of voltage excitation which can be supplied to the product to produce an output which is proportional to force but due to ratiometricity errors may not remain within the specified performance limits. Non-compensated force sensors, excited by constant current (1.5 mA) instead of voltage, exhibit partial temperature compensation of span.
3. The output signal obtained when the zero force is applied to the sensor. Also known as "null" or "zero".
4. The change in the null resulting from a change in temperature .It is not a predictable error as it can shift up and down from unit to unit. Change in temperature causes the entire output curve to shift up or down along the voltage axis.
5. The algebraic difference between output signals measured at the upper and lower limits of the operating force range. Also known as "full scale output" or simply "span".
6. The maximum deviation of product output from a straight line fitted to output measured over the operating force range. The straight line through a set of points which minimizes the sum of the square of the deviations of each of the points from the straight line.
7. The ratio of output signal change to the corresponding input force change. Sensitivity is determined by computing the ratio of span to the specified operating force range multiplied by the supply voltage being used.
8. The maximum deviation in sensitivity due to changes in temperature over the operating temperature range, relative to sensitivity measured at 25 °C.
9. The maximum difference between output readings when the same force is applied consecutively, under the same operating conditions, with force approaching from the same direction within the operating force range.
10. The maximum force which may safely be applied to the product for it to remain in specification once force is returned to the operating force range. Exposure to higher forces may cause permanent damage to the product. Unless otherwise specified, this applies to all temperatures within the operating temperature range.

Notes:
1. The temperature range over which the product may safely be exposed without excitation or force applied. Under these conditions the product will remain in specification after excursion to any temperatures in this range. Exposure to temperatures beyond this range may cause permanent damage to the product.
2. MCTF is a basic measure of reliability for a non-repairable device. It is the mean number of cycles to maximum operating force over which
a sensor can be expected to operate until failure. The mean value is determined statistically from a probability distribution for failures
based upon test data. MCTF may vary depending on the specific application in which a sensor is utilized.

Notes:
1. The extreme limits that the product can withstand without damage to the product.
2. The temperature range over which the product may safely be exposed without excitation or force applied. Under these conditions, the product will remain in the specification after excursions to any temperature in this range. Exposure to temperatures beyond this range may cause permanent damage to the product.
3. The maximum temperature and duration to which the product may be exposed for processing the solder electrical connections.
