Omron EE-SX954-R 1M — amplified slot sensor for tight-registration sensing
The Omron EE-SX954-R 1M is an amplified through-beam photomicrosensor from the EE-SX95 series, with a 0.197 mm slot. It outputs an NPN open-collector signal selectable between Dark-ON and Light-ON. Supply voltage is 24 V. Rated for chassis-mount installation and operating from -25°C to 55°C.
The sensing slot is 0.197 mm wide. The flag or encoder wheel passing through must be thinner than that gap. Compare to the EE-SPX613 with a 0.236 mm slot.
That means Omron is still manufacturing it, and there's no last-time-buy deadline to chase. The 1-meter cable version (the 'R 1M' suffix) is the standard robotic-grade variant — the cable jacket handles flexing in cable-track applications better than the basic version.
