KÜBLER
Kuebler - Magnet sensor LI20 with magnetic ring RI20
The combination RI20/LI20 is used to measure length via a rotary shaft, e.g. in woodturning machines, materials handling, overhead cranes, etc. This sensor is more or less totally impervious to chips, oil, dust and water and thus can be used in troublesome environments, it is sealed and has no moving parts. The sensor is fitted to read on a yoke. This yoke is available for shaft dimensions 8-30 mm. There are three different yoke sizes; 31 mm, 41.2 mm and 45 mm.
The yoke RI20 has a pole distance of 2 mm. The distance between the sensor and the yoke should be 0.1 to 1.0 mm (recommended 0.4 mm). For the magnet sensor, the slope must not exceed ±3°, the rotation must not exceed ±3° and the offset must not exceed ±1 mm.
The following information is required to select the right combination:
- yoke size
- max. shaft rotation speed (given the frequency to following systems)
Pulses/revolution | Yoke | Magnet sensor | Max. revolutions (rpm) |
250 | RI20.031.XXXX | LI20.11X1.2005 | 12000 |
1000 | RI20.031.XXXX | LI20.11X1.2020 | 2400 |
2500 | RI20.031.XXXX | LI20.11X1.2050 | 3900 |
1024 | RI20.041.XXXX | LI20.11X1.2016 | 7000 |
360 | RI20.045.XXXX | LI20.11X1.2005 | 12000 |
3600 | RI20.045.XXXX | LI20.11X1.2050 | 2700 |
- Robust and able to withstand vibration
- Easy to install
- High resolution
- IP67. Impervious to chips, oil, water, etc.
