Product Overview
The EE-SX674 is a T-shaped close-mounting slot photomicrosensor with a 5 mm slot width and 9 mm slot depth, from Omron's EE-SX47 / SX67 family of amplified through-beam sensors with built-in connector. The "T-shape, slot center 10 mm" profile (Omron calls this "close-mounting" because the slot is set back from the front face for close-coupling to a moving target) gives the SX674 a slightly deeper sensing throat than the SX672 (slot center 7 mm) — making the SX674 the right pick when the target arm or flag is 10 mm or wider, while the SX672 is better for narrower 7 mm arms.
Where the EE-SX674 fits in the EE-SX67 family
The EE-SX47 / SX67 family splits along three axes: profile (standard / L-shaped / T-shaped 7 mm / T-shaped 10 mm / F-shaped / R-shaped), output (NPN or PNP), and connection (connector model or pre-wired -WR). The "674" is the T-shaped close-mounting profile with slot center 10 mm, NPN output, connector model. The full T-shaped 10 mm lineup: EE-SX674 (NPN connector, this SKU), EE-SX674A (Dark-ON fixed), EE-SX674R (Light-ON fixed), EE-SX674P (PNP), EE-SX674-WR (NPN pre-wired), EE-SX674-WR 1M (pre-wired 1 m cable), EE-SX676-WR (pre-wired 5 mm slot different profile). Pick the EE-SX674 when you need NPN output, a 4-pin connector, and Dark/Light-ON selectable logic.
Connector, L terminal, and wiring the EE-1006 harness
The EE-SX674 ships as a bare sensor body with 4 PCB pins on the rear — you must purchase an EE-1006 (1 m / 2 m) or EE-1010 (1 m / 2 m) connector harness separately (the EE-1006A hold-down clip is optional). The harness has 4 colour-coded wires: brown = +V, blue = 0 V, black = OUT (NPN open-collector), pink = L terminal. For Dark-ON (output ON when beam is broken), leave the pink wire disconnected or connect it to 0 V. For Light-ON (output ON when beam is unblocked), short the pink wire to the brown +V wire with a small jumper.
Application fit and mounting
The EE-SX674 is the workhorse slot sensor for limit-switch-replacement applications on packaging machines, conveyor lines, and assembly automation — wherever a metal flag or plastic tab passes through a 5 mm slot. Common uses: end-of-stroke detection on a pneumatic cylinder rod, label-presence detection on a packaging line, pulse counting from a rotating shaft with a slotted disc (up to 1 kHz), home-position detection on a linear slide, cam-position verification on a rotary indexing table, and door open/closed detection on a control cabinet. Mount with two M3 screws through the 9.5 mm clearance holes in the sensor body, tightened to 0.4-0.5 N·m torque.

- Home-position detection on a linear slide — flags the slide at the home position
Buying Checklist
- Pick EE-SX674 for T-shaped close-mounting slot sensor with selectable Dark/Light-ON, NPN output, connector
- Pick EE-SX674-WR for pre-wired version
- Pick EE-SX674A for Dark-ON fixed
- Pick EE-SX674R for Light-ON fixed
- Pick EE-SX674P for PNP sourcing output
- Pick EE-SX672 for narrower target arms — slot center 7 mm

FAQ for EE-SX674
What's the difference between EE-SX674 and EE-SX672?
Both are T-shaped close-mounting slot sensors with NPN open-collector output and selectable Dark/Light-ON logic. The only difference is the slot center position: EE-SX674 (this SKU) has a slot center 10 mm from the mounting face (deeper sensing throat, suited for targets 10 mm or wider), while EE-SX672 has a slot center 7 mm from the mounting face (shallower throat, suited for narrower targets 7-9 mm wide).
Do I need to buy a connector harness for the EE-SX674?
Yes — the EE-SX674 ships as a bare sensor body with 4 PCB pins on the rear. You must purchase a connector harness separately. The compatible harnesses are: EE-1006 1M (1 m PVC cable, 4 conductors), EE-1006 2M (2 m PVC cable), EE-1010 1M (1 m PVC cable, 4 conductors, equivalent to EE-1006), EE-1010 2M (2 m PVC cable), and EE-1010-R 1M / 2M (robot cable for high-flex applications). The EE-1006A hold-down clip is optional and recommended for vibration-prone installations.
How do I wire the EE-SX674 for Dark-ON vs Light-ON operation?
The 4 wires on the EE-1006 harness are colour-coded: brown = +V (5 to 24 VDC supply), blue = 0 V (ground), black = OUT (NPN open-collector output), pink = L terminal (Light/Dark select).
Can the EE-SX674 be used to count pulses from a rotating shaft?
Yes — the EE-SX674 has a response time of 0.17 ms, which translates to a maximum counting frequency of about 1 kHz (500 pulses per second in each direction, since each pulse requires a transition). For a single-channel pulse-counting application, mount a slotted disc on the rotating shaft with the slot pattern passing through the EE-SX674's 5 mm slot.
