Notes on using recommended replacements
| Recommended replacements | Sensing performance | Specifications | Output circuit | Mounting dimensions | Dimensions | Case color |
|---|---|---|---|---|---|---|
| SF4D series (Hand protection type) | ◎ | ＊ | ＊ | ＊ | ＊ | * |
◎ Highly interchangeable
○ Almost no difference
＊ Large differences
- Differences in sensing characteristics, shapes and installation procedure.
- Mounting brackets and connector cables (bottom cap cable) are not supplied with the light curtain. Be sure to order them separately.
