What's this please? (Component Advice)

I'll have to trace the pinouts but yes I think it might be an Analog Devices clone of some kind or maybe a Cirrus. The board has a 2019 date on the silkscreen but I am certain it's an obsolete part that was cloned.

nali:
Does anyone recognise this type of encoder please? It's an Alps brand quadrature but I can't seem to find it on the 'net. The only markings are the "Alps" name and "140r" but Google doesn't throw up anything useful.

DC1MC:
@nali: This really look like a potentiometer, you sure that is an encoder (continuous rotation and giving pulses) and not a variable resistor, I've never seen this this stile of ALps encoders, even for the panel mounts ?

Could you measure in between the side  contacts and/or center and one side with an ohmeter and rotate the shat  ?

Bud:
Looks a potentiometer to me... 140 Ohm perhaps, though it seems a weird value. A simple test with an Ohm meter would tell.

In case is an actual encoder maybe you find some compatible one (same shaft length, diameter) on Leo Bodnar's store:
