I’m working on adding extra access control to elevator calling buttons and i would like to identify the connector type of the wires connecting elevator buttons to the elevator panel
I have tried Micro JST 1.25MM 3-Pin Male & Female Connector Plug, it has the same Pitch Mating size of 1.25mm but unfortunately the connector itself is smaller than the original one.
Maybe you can use this to find more connectors that could match yours: https://connectorbook.com/identification.html?m=NT&n=lo_prof_1r_w2b_conn_1p2 It has a pretty handy identification tool (you can even browse by pictures). It usually suggests quite an amount of connectors but it can guide you in the right direction and you can look at the according datasheets to find out more. By the way the creator of this community made that homepage and a book related to it (or probably the other way round 😅).
I just want to say I appreciate the hell out of the way you annotated the photo
