That 1.5 m range and 0.3 ms response make it a classic pick for transparent material detection (bottles, film, glass) on packaging lines or conveyor gates. It runs on 12 to 24 VDC, outputs as PNP or NPN 3-wire (user-configurable light-on/dark-on), and draws a max load of 100 mA. The housing is ABS/polycarbonate rated IP67 and NEMA 3/4/4X/6/12/13, so it's fine in washdown or dusty environments. LED indicators show output (yellow) and stability (red). The only real difference between XUKT1KSMM12 and XUKT1KSML2 is the connection method. This part has a 4-pin micro DC connector (mate-in a pre-wired cordset); the ML2 version has a 2-meter PVR cable pigtail. Every other spec – sensing range, response time, output, voltage, IP rating – is identical. For a BOM line, if the panel was wired for a pigtail, you can still use this connector version with a cheap M12-to-flying-leads cordset (e.g., 4-wire, 24 VDC rated). No rewiring inside the sensor. If the design specifically called for the cable version to avoid an extra joint, the ML2 is a direct swap. For a new build, the connector version gives you flexibility to replace a damaged cable without swapping the whole sensor – margin lives in that ease-of-service. ## Integration notes for panel builders and techs Response time at 0.3 ms is fast enough for counting small bottles at moderate line speeds (1500 Hz operating frequency). If the application needs longer range, the non-polarized retroreflective XUK1APBNM12 offers 9 m but at a slower 2 ms response. For polarized, the XUK9APBNM12 gives 5 m with the same 2 ms trade-off – stay with this one if the 1.5 m reach and fast detection are what your machine needs.","metaTitle":"XUKT1KSMM12 Polarized Retroreflective Sensor, 1.5m, IP67","metaDescription":"Active Square D XUKT1KSMM12 polarized retroreflective sensor. 1.5m range, 12-24 VDC, PNP/NPN, IP67. 4-pin DC micro connector.
