Slot sensor for tight registration and edge detection
The EE-SX674P-WR 1M: Through-beam photomicrosensor in the EE-SX67 series, detecting a flag through a 0.197 mm slot. PNP output selectable for Dark-ON or Light-ON, switching current 0.05 A.
Slot width and output — what they mean on the bench
The 0.197 mm slot is tight — it will catch a thin metal flag or a punched tape edge, but not a thick bracket. The EE-SPX613 sibling uses a 0.236 mm slot and NPN output; if your PLC input card is sinking (NPN), that part avoids a level shifter. Both are through-beam chassis-mount modules, but the EE-SX674P-WR 1M gives you the PNP selectable output and a narrower slot for finer resolution.
