This is a DIY cable kit to make your own thermistor/end-stop/other 2 pin extensions. In this bag we have 5 pieces of JST-XH 2 pin housing with 15 pcs female socket pins. Crimp tool not included. You can use needle nose pliers but for best results a proper crimp tool is best. This piece will connect to the standard end-stop/thermistor plug found on most printers.
