Omron / Sentech E3AS-F1000I TOF Laser Distance-Settable Photoelectric Sensor

E3AS-F1000I

The Omron E3AS-F1000I is a compact distance-settable photoelectric sensor in the E3AS-F series that uses time-of-flight (TOF) measurement with a 940 nm infrared Class 1 laser to detect objects from a 50 mm minimum distance out to a teachable set distance of up to 1,000 mm (white paper), independent of target color or surface. It offers a 90 ms maximum response time, NPN or PNP control outputs (100 mA), and IO-Link communication (Ver. 1.1, COM2 38.4 kbps / COM3 230.4 kbps) for fast startup and changeover. The sensor is available in a SUS316L stainless-steel body or a PBT/PC plastic body, both rated IP67/IP67G/IP69K with antifouling lens coatings and Ecolab certification for washdown environments. It operates on 10 to 30 VDC over an ambient temperature range of -20 to 55 C, with the lens made of PMMA.

Technical overview

The Omron E3AS-F1000I is a distance-settable photoelectric sensor that uses time-of-flight (TOF) measurement rather than triangulation or intensity thresholding. It emits a 940 nm infrared Class 1 laser (IEC/EN 60825-1:2014) and times the round-trip of the reflected pulse, so it reports presence based on absolute distance to the target. The teachable set distance spans 100 to 1,000 mm (against white paper) with a 50 mm minimum sensing distance, and because TOF measures distance directly, detection is largely independent of target color and surface finish. In practice that means one sensor can be taught to a single background-suppression threshold and then reliably catch dark, glossy, matte, or mixed-color objects crossing the beam without re-tuning per SKU. The 90 ms maximum response time (operate or reset) places this firmly in the presence-detection and trigger role rather than high-speed counting of fast-moving small parts.

Electrically, the sensor runs on 10 to 30 VDC (Class 2, 30 mA max) and provides switchable NPN or PNP control outputs in a push-pull/open-collector configuration, with OUTPUT1 as normally-open and OUTPUT2 as normally-closed, each rated to 100 mA. That dual NO/NC pairing lets you wire both a 'part present' and a complementary 'clear' signal into a PLC or vision controller without external logic. Beyond simple switching, it carries IO-Link Ver. 1.1 (COM2 38.4 kbps / COM3 230.4 kbps), which is the feature that changes how it is designed in: the set distance, output behavior, and diagnostics can be configured and stored centrally, so changeover and sensor replacement become a parameter download rather than a manual teach. Connection options cover pre-wired 2 m / 5 m cables, an M8 connector, an M8 pre-wired pigtail (0.3 m), or an M12 Smartclick pre-wired connector (0.3 m), giving flexibility between hard-wired runs and quick-disconnect maintenance.

The mechanical and environmental side is built for harsh, hygienic lines. The body is offered either in SUS316L stainless steel or in PBT/PC plastic, with a PMMA lens, and both versions are rated IP67 / IP67G / IP69K with antifouling lens coatings and Ecolab certification for chemical washdown. At just 11.4 x 38 x 22 mm and approximately 90 g (metal, 2 m pre-wired) or 30 g (M8 connector), it fits tight conveyor framing and guarding. The operating range of -20 to 55 C (storage -40 to 70 C, no icing or condensation) covers chilled and ambient food, packaging, and logistics environments. Together these specs describe a sensor meant to be installed once across any conveyor-line width within the 1,000 mm reach, survive high-pressure cleaning, and serve as a stable presence/trigger source that does not drift as product mix changes.

Best for

  • Object-present triggering across conveyors of varying width, since a single taught set distance up to 1,000 mm works regardless of belt span within range
  • Detecting mixed-color, glossy, or dark packaging where intensity-based sensors fail, because TOF distance measurement is independent of target color and surface
  • Washdown food and beverage lines requiring IP69K, antifouling lens coating, and Ecolab certification with a hygienic SUS316L stainless body
  • Logistics and sortation gates where a stable 'box present / clear' signal is needed via the NO/NC dual outputs into a PLC
  • Lines using IO-Link for centralized setup and fast changeover, where set distance and parameters are downloaded rather than manually re-taught on each replacement

Selection notes

  • Confirm the 90 ms maximum response time is fast enough for your line speed; at high belt speeds or for small, closely-spaced parts this sensor is a presence/trigger device, not a high-rate counter
  • The 1,000 mm set distance is rated against white paper, so very low-reflectance or extreme-angle targets may reduce usable range; validate the worst-case target at the actual mounting distance (50 mm minimum)
  • Choose the body variant deliberately: SUS316L stainless for hygienic washdown and chemical exposure, or the lighter PBT/PC plastic body where cost and weight matter more than full metal robustness
  • Decide on the output and connectivity early: NPN vs PNP plus NO (OUTPUT1) / NC (OUTPUT2) wiring, and whether you will use IO-Link Ver. 1.1 (COM2/COM3) for configuration and diagnostics versus standard SIO switching
  • Match the connection style to maintenance needs: pre-wired 2 m / 5 m for permanent runs, or M8 / M12 Smartclick pre-wired connectors for quick-disconnect replacement and reduced spares downtime
  • Verify the -20 to 55 C operating window and avoid icing/condensation; for sub-zero chilled rooms confirm the installation point stays within the rated range
