- Encoder TONiC with a scale tape from Invar RELM
The new high-precision RELM line provides high speed and non-contact readout in combination with new solutions including dynamic signal processing and IN-TRAC ™ - optical zero mark with automatic synchronization. TONiC encoder system with the RELM ruler is exceptionally resistant to external influences, while providing the performance inherent only to encoders with a much smaller scale step. With an accuracy of ± 1 μm, low thermal resolution and resolution up to 1 nm, the RELM line meets the highest requirements for precision motion measurement systems.
The system includes the following components:
- invar ruler RELM with a step of 20 microns,
- reading head TONiC T1000,
- an analog or digital Ti-interface.
Features and Benefits of the TONiC T1010 and Ti-Interface Reader
- Periodic error: ± 30 nm, which ensures the accuracy of operation inherent in encoders with a smaller pitch.
- Compact overall dimensions: 10.0 × 35.0 × 13.5 mm (H×D×W).
- Extremely high signal stability under conditions not acceptable for most open optical encoders.
- User selectable automatic gain adjustment (AGC) mode allows to maintain a constant analog signal amplitude of 1 Vpp.
- Ability to work at speeds up to 10 m/s and temperatures up to 70 ° C.
- New opportunity! Increase the stability of positioning due to the optical signal filtering system, characterized by low noise (jitter).
- Standard analog and digital output signals.
- Easy setup and diagnostics of the system thanks to LED indicators on the reading head and interface.
- The flexible cable between the reading head and the UL-compliant interface is up to 10 m long.
- Compliance with the requirements of the RoHS directive.
Invar RELM ruler with 20 μm pitch
RELM ruler in 20 μm increments is made of Invar, a nickel-iron alloy having a low expansion coefficient. Due to the high strength of Invar from it, it is possible to produce rulers with a much smaller cross section than glass. At the same time it is easier to handle Invar rulers during transportation and installation, without risking to break them.
- A number of standard rulers are produced, custom-made lines of non-standard lengths are available on request.
- Accuracy up to ± 1 μm, certified for each line separately with verification in accordance with international standards.
- Low coefficient of thermal expansion: Invar, ≈ 0.6 μm / m /0С (0 0C — 30 0C).
- Optical zero mark IN-TRAC ™ with automatic synchronization provides two-way repeatability of arrival to zero point at speeds of up to 10 m/s.
- The mean (RELM) and the extreme (RELE) positions of the zero mark are provided as standard.
- Pair limit switches installed directly on the line provide an automatic feed of the signal that initiates the stop of the moved assembly.
- Easily installed, directly on the substrate, using the base bracket and clamps or self-adhesive base.
