Cables with Connectors on Both Ends
for Branch Connector
| Appearance | Model | Cable length |
 | F39-JF1S | 1 m |
| F39-JF2S | 2 m | |
| F39-JF5S | 5 m | |

Mutual Interference Prevention Filter (for E3ZS)
| Dimensions | Model | Quantity | Remarks |
 | E39-E11 | 2 per Emitter and Receiver (4 total) | For use with E3ZS-T81A. This filter prevents mutual interference by changing the direction of polarized light of the 2 adjacent Emitter/Receivers. However, when the filter is attached, the maximum sensing distance of the E3ZS is reduced to 1.5 m. |
