    Hi,

    I´m newbie in here and disassembling Bosch AHC 24V DC motor from adjustable table. There is also small circuit in the end of the same connection cable and I can not figure out what it is.

    Any suggestions are gladly welcome!
    Thank you.

    Pictures from circuit and motor attached.

    Really need a photo of the other side. Looks like it may be a reversing or limiting circuit.

    Appears to be a photo slot sensor or hall effect type sensor.
    Is there a No. on the 3pin devices?

    Yes, that circuit might very well be part of an encoder for position and speed monitoring

    Although with only three wires, two for power one for signal the info may be a little limited?;)
