    Default NPN or PNP Sensor?

    I moved my Shopbot and the only problem that I had was a broken proximity sensor. I found the sensor listed at http://www.clrwtr.com/PDF/SUNX/SUNX-...ty-Sensors.pdf . I'm not sure if I need the NPN or the PNP version? Any help would be greatly appreciated.

    PRT models have NPN, normally open. PRS are NPN, normally closed
