Disclosed is a run-length limited self-resetting type limit encoder, comprising a driving motor (13), a motor output shaft (12), a control circuit board (3) and a transformer (4); a worm wheel box of the driving motor is provided with a motor cover plate (5), a through-hole is provided in the middle of the motor cover plate, and the motor output shaft is mounted in the through-hole; a front end of the motor output shaft is connected to a photoelectric encoding mechanism; the photoelectric encoding mechanism, the driving motor and the transformer are all connected to the circuit control board; a signal is transmitted between the circuit control board and the photoelectric encoding mechanism, the driving motor and the transformer via a circuit; and the circuit control board is provided in an electric motor. The run-length limited self-resetting type limit encoder has a simple structural design, low production costs, is convenient to mount, is accurate in limitation and can reset automatically. |
