our sensor used for the SSM winding machine, when you confirm the order, you didn't tell us you buy it for your own built machine, not the SSM machine, and our sensor can be used directly when you get it, but you changed the connector by yourself, that caused the problem. it is not our quality problem caused,okay? we send a lot to our clients and this sensor sells very hot, no any quality issues so far.

thank you very much and hope can work with you more. :)
