| Cable |
0.1-mm2 4-core bending-resistant cabtyre cable, PVC, 1 m 3.281 ft long
(Note) : The cable is a bending-resistant cable usable on a moving base. When the sensor is mounted on a moving base, secure the sensor cable joint at the unit in place so that stress is not applied to it.
(Note) : When storing, make sure that the cable does not come into contact with the sensing section or operation indicator. |
| Wiring length |
Extension up to total 100 m 328.084 ft is possible with 0.3 mm2, or more, cable.
(Note 1) : If the cable is extended to 20 m 65.617 ft or longer, confirm that the supply voltage at the end of the cable attached to the sensor is 4.5 V or higher.
(Note 2) : For safety applications, do not exceed 30 m 98.425 ft. |
