Product Overview

The Omron EE-SX674-WR is the pre-wired sibling of the EE-SX674 slot photomicrosensor — same T-shaped close-mounting body with 5 mm slot width and 9 mm slot depth, but with a permanently attached 4-conductor robotic cable instead of a 4-pin system connector. 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. This makes the EE-SX674-WR the right pick when the sensor head is mounted in a location where a separate harness would be at risk of vibration loosening (presses, stamping machines, robotic weld cells) or when a sealed cable entry through a control cabinet wall is preferred to a removable connector. The EE-SX47 / SX67 family is split along three axes: profile (standard / L-shaped / T-shaped 7 mm / T-shaped 10 mm), output (NPN or PNP), and connection (connector model or pre-wired -WR). The slot is set back 10 mm from the mounting face (the close-mounting feature), which means the moving target can come within 10 mm of the sensor face without mechanical interference — useful for short-stroke pneumatic cylinders.

Key Features

  • Response time 0.17 ms
  • Current consumption 12 mA max
  • NPN open-collector output, 100 mA switching current
  • T-shaped close-mounting slot photomicrosensor, slot center 10 mm
  • SKU: EE-SX674-WR
  • Series: EE-SX47 / SX67 (Slot-type photomicrosensor, non-modulated)
  • Voltage: 24 VDC

Best-Fit Applications

  • Home-position detection on a linear slide where the sensor body sees direct cable flex — the EE-SX674-WR robotic cable is.
  • End-of-stroke detection on a pneumatic cylinder where vibration risks loosening a connector — the pre-wired cable eliminates that failure mode
  • Label-presence detection on a packaging line where the sensor head is mounted inside the machine frame and the cable routes.

Buying Checklist

  • Pick EE-SX674P-WR for PNP sourcing output
  • Pick EE-SX674R for Light-ON fixed — typical for fail-safe absence detection
  • Pick EE-SX674A for Dark-ON fixed — cannot be accidentally switched to Light-ON

FAQ for EE-SX674-WR

What's the difference between EE-SX674-WR and EE-SX674?
The only functional difference is the connection method. EE-SX674 (this SKU's connector sibling) ships as a bare sensor body with 4 PCB pins on the rear and requires a separate EE-1006 (1 m / 2 m) or EE-1010 (1 m / 2 m / robot-cable) connector harness. EE-SX674-WR (this SKU) ships with a 1 m robotic cable permanently attached to the sensor body — no separate harness to buy, no connector to loosen over time.
What are the four wire colors and what does each do?
The EE-SX674-WR has 4 colour-coded wires moulded into the robotic cable: brown = Vcc (5 to 24 VDC supply), pink = L (Light/Dark select terminal), blue = GND (0 V supply), black = OUTPUT (NPN open-collector output to the PLC input). The colour coding is identical to the EE-1006 / EE-1010 harness used with the connector-model EE-SX674 — so if you migrate between the connector and pre-wired variants, the wiring is the same.
How long can the cable be on the EE-SX674-WR?
The EE-SX674-WR is available in four standard cable lengths: 1 m (this SKU), 2 m, 5 m, and 7 m. The model number changes to EE-SX674-WR 2M, EE-SX674-WR 5M, or EE-SX674-WR 7M.
Can I cut and re-terminate the cable on the EE-SX674-WR?
Yes — the cable can be cut to length and re-terminated with any standard 4-conductor connector (M8, M12, or terminal block) provided the conductor-to-connector mapping is preserved (brown = +V, pink = L, blue = 0 V, black = OUTPUT). The cable is a standard 4-conductor robotic cable, so any M8 / M12 4-pin connector can be attached.
