Sensors
Slotted photoelectric sensors, slot width 5 mm. A vane enters the slot and the output changes state. One for home, two for positive and negative limits.

Function
The infrared emitter and receiver sit on the two sides of one U housing. A vane entering the 5 mm slot blocks the beam and the output changes state. Detection does not depend on color, and nothing is mounted on the opposite side. It fits a stage, a nut block, or a home dog.
| Use | Qty | If you leave it out |
|---|---|---|
| Home | 1 | After power-up the absolute position is unknown and the move does not start from the same point |
| Positive and negative limits | 2 | A program error or a failed home can drive into the hard stop |
How to choose
- New bracket: start with SX674-WR, flush mount, 7 mm hole pitch, 1 m cable.
- Existing holes: use the table. Pitch 19: 670 / 671 / 672. Pitch 7: 673 / 674 / 676 / 677. Slot center height 10 mm: 675. Do not rework the holes to force a fit.
- Then the cable exit. 670–674 can be a connector or a cable. 675 / 676 / 677 are cable only.
- Then the logic. Limits usually use dark-ON (black wire). For home, choose black or white from the homing direction. Do not land both wires on the same input.
Standard models
Units are mm.

Order code
The usual code is SX674-WR. Home 1 + limits 2, three pieces by default.
| What to state | Example |
|---|---|
| Code | SX674-WR |
| Quantity | Home 1 + limits 2 |
| Cable exit | Cable 1 m; if longer, state the metres |
Other outlines use the model in the table plus a suffix. No suffix, or A, is the connector. -WR is a 1 m cable. 675 / 676 / 677 are cable only.
