Ⅰ、Overview
GTM series miniature Hall magnetic induction self-resetting displacement sensor, is a non-contact Hall magnetic induction sensor, the internal use of induction magnetic cylinder and microcontroller chip processing circuit in two parts, the internal magnetic cylinder back and forth retraction, the circuit of the Hall magnetic induction programmer chip to produce magnetic induction, through the internal processing circuit output different analog or digital signals, the size of the output signal value and the actual displacement distance is a linear relationship of proportional to the size of the signal. The size of the output signal is proportional to the actual displacement distance.
