TONiC™ RSLM encoder system

The new RSLM stainless steel spar scale offers performance to rival fine pitch glass scales yet is available in lengths up to 5 m. RSLM offers a total accuracy (including slope and linearity) better than ±4 μm over 5 m – an industry first! With ±30 nm cyclic error, patented filtering optics, resolution to 5 nm and simple installation, RSLM retains all of the benefits of a 20 μm encoder yet provides the performance of a fine pitch system.

RSLM 20 µm pitch stainless steel scale

20 µm RSLM stainless steel scale is perfect for long travel applications where metrology can not be compromised.

• The robust spar scale is available in defined lengths up to 5 m
• Total accuracy better than ±4 µm over 5 m
• Thermal expansion: 10.8 µm/m/°C
• RSLM can be coiled for simple storage and handling, yet once uncoiled behaves as a spar scale
• Mounted using specially formulated adhesive tape or mechanical clips
• IN-TRAC™ auto-phase optical reference mark, bi-directionally repeatable even at maximum speed (10 m/s)
• Multiple IN-TRAC™ reference mark positions: scale mid-point (RSLM), scale end-point (RSLE), distance coded for short travel indexing (RSLD) or regularly spaced for customer selection (RSLC)
• Dual optical limits provide on-scale end-of-travel indication
