Product Summary:
The GTM series of micro Hall magnetic induction self-resetting displacement sensors is a non-contact Hall magnetic induction sensor. It consists of two parts: an induction magnetic cylinder and a single-chip microcomputer chip processing circuit. The internal magnetic cylinder extends and retracts back and forth, and the Hall magnetic induction programming chip in the circuit generates magnetic induction. Different analog or digital signals are output through the internal processing circuit. The magnitude value of the output signal is in a direct proportional linear relationship with the actual displacement distance.
