A502 sensors are square standard sensors with a 2-pin male connector. They have a force range of 0-222 N (0-50 lb), specified with Tekscan electronics. The model is linear through a much lower range of 0-22N (0-5 lb), and is capable of measuring loads up to 44,482 N (10,000 lb).
The dynamic range of this mini force sensor can be modified by changing the drive voltage and adjusting the resistance of the feedback resistor (see below in “How to Adjust the Force Range“).

How to Adjust the Force Range:
* In order to measure higher forces, apply a lower drive voltage (-0.5 V, -0.25 V, etc.) and reduce the resistance of the feedback resistor (1k? min.) To measure lower forces, apply a higher drive voltage and increase the resistance of the feedback resistor.
Linearity (Error):?< ?3% of Full Scale (Line drawn from 0 to 50% load)
Repeatability:?< ?2.5% (Conditioned Sensor, 80% of Full Force Applied)
Hysteresis:?< 4.5 % of Full Scale (Conditioned Sensor, 80% of Full Force Applied)
Drift:?<5% / logarithmic time (Constant Load of 111 N (25 lb))
Response Time:?< 5 ?sec (Time required for the sensor to respond to an input force; Impact load – recorded on Oscilloscope)
Operating Temperature:?-40?C – 60?C (-40?F – 140?F)*
* Force reading change per degree of temperature change = 0.36%/?C (?0.2%/?F)
