Product Overview

The Omron EE-SX670 is the standard-body model of Omron's EE-SX67 family — a fixed-gap slot photomicrosensor with a U-shaped body, 5 mm slot width, and a system connector on the rear of the unit. manufactured by Omron Corporation. Hengyixin Automation ships this sensor from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.

The slot houses an infrared LED on one side and a phototransistor on the other; any opaque part passing through the slot blocks the beam and toggles the output. The 25.4 × 22.2 mm rectangular PBT body has 2 mm mounting holes on each side and snaps directly to the EE-1001 connector harness — the wiring is field-replaceable without re-stripping or re-soldering.

For a pre-wired integral cable, skip the connector and order the EE-SX670-WR or EE-SX670-WR 1M which have the cable moulded in.

Key Features

  • 5 mm slot width for small-part detection
  • NPN open collector output, 100 mA direct switching
  • Standard-body EE-SX67 family — flat-mountable on brackets with 2 mm side holes
  • 0.17 ms response time — adequate for high-speed counting up to 1 kHz
  • SKU: EE-SX670
  • Series: EE-SX47 / EE-SX67 (EE-SX67 family, 50–100 mA direct switching)
  • Voltage: 5 TO 24 VDC

Best-Fit Applications

  • Edge / position detection on feeders and label applicators where a tab passes through the 5 mm slot
  • Part-out detection on vial or syringe counters in pharmaceutical assembly
  • Tape end-of-reel detection in automated tape feeders where the splice triggers an alarm

Buying Checklist

  • Pick the EE-SX670-WR when you want a 1 m integral pre-wired cable
  • Pick the EE-SX671 when the sensor must mount with the slot axis parallel to the bracket surface
  • Pick the EE-SX672 when you need to mount the sensor mid-air with a 7 mm slot center

FAQ for EE-SX670

What's the difference between the EE-SX670 and the EE-SX670-WR?
The SX670 (this SKU) has a connector system on the rear that mates with the EE-1001 (1 m) or EE-1001-1 (500 mm) harness. The SX670-WR has a 1 m PVC cable moulded directly into the housing with the same colour code. Pick the SX670 + EE-1001 when the cable route has a service loop or a kink point where you want the option to unplug the sensor without cutting the cable.
Can the EE-SX670 drive a relay coil directly?
Yes. The NPN output sinks up to 100 mA at 30 VDC, so it can drive small 24 VDC relay coils (G2R-1-S DC24 for example) or 24 VDC indicators directly. With the G2R-1-S-DC24 coil, the 24 VDC supply goes to the brown wire, blue to 0 V, and black to the relay coil positive (negative to 0 V).
How do I select Dark-ON vs Light-ON on the EE-SX670?
Use the pink (or orange, depending on harness revision) wire on the EE-1001 harness. Leaving the wire open (not connected) selects Light-ON — the output transistor is ON when the slot is clear and turns OFF when a part enters the slot. Tie the wire to 0 V (blue) to select Dark-ON — output is OFF when clear and ON when a part enters.
What's the smallest part the EE-SX670 can detect?
0.5 mm opaque material at high speed (sub-millisecond response) — but for reliable 5 ms response in industrial conditions target at least 1.4 × 5 mm opaque material. Translucent or thin coloured objects may need the EE-SX670-P (PNP with stronger IR drive) or the EE-SX970 visible-red LED slot sensor which can see red and amber translucent targets.
