Mini Shaft information system LIMAX1M position detection up to 90 m conveying height
The pseudo-absolute shaft copying system offers not only the smallest sensor in the entire LIMAX series, but is also a particularly cost-effective solution for the detection of conveying heights up to 90 meters.
During commissioning, a one-time referencing is required, which must be requested by the lift control. LIMAX1M is then auto-referencing, i.e. the system automatically detects the absolute position after a travel of 240 mm. Flexible mounting options ensure simple and fast mounting during initial installation or when the measuring system needs to be replaced.
- Fits into the smallest gap - extremely compact design
- Attractive price
- Low power consumption
- Pseudo-absolute shaft information system
- Connection via RJ45 or Mini-USB
- Simple assembly
- Suitable for cloud applications
