RENISHAW SiGNUM high accuracy
stainless steel scale RSLC A-9686-XXXX Renishaw: RSLM / E / R / C 20µm - Stainless Steel scale
RSLM / RSLE / RSLC high accuracy stainless steel scale
The RSLM spar scale is an exciting addition to the range,
which 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! RSLM is perfect for long travel
applications where metrology cannot be compromised. This high accuracy scale is offered with multiple IN-TRAC™ reference
mark positions: Scale mid-point (RSLM) 20 mm or 70 mm from the scale end-point (RSLE) Regularly spaced every 200 mm for customer selection (RSLC) The RSL range of scales are compatible with VIONiC™ and TONiC™ readheads Why choose the RSL range of high accuracy stainless steel
scale? Robust, yet highly precise, steel spar scale Total accuracy better than ±4 µm over 5 m Thermal expansion: 10.1 ±0.2 µm/m/°C @ 20 °C Mounted using specially formulated adhesive tape or
mechanical clips Available in defined lengths up to 5 m RSLM can be coiled for simple storage and handling, yet once
uncoiled behaves as a spar scale Can be used as part of a Functional Safety system when used
with TONiC™ FS readheads. IMPORTANT: Only self-adhesive mounted RSLM
scale is FS approved. Clip and clamps must not be used to mount RSLM
scale in an FS application.>/li>
RSLM20 is a stainless steel spar scale featuring 20 µm pitch
and a variety of IN-TRAC optical reference mark options, including
regularly spaced for customer selection or single reference at the centre or
close to the end.
It is comparable to fine pitch glass scales and offers a total accuracy
(including slope and linearity) better than ±4 µm over a 5 m length. It can
also be coiled for simple storage and handling yet once uncoiled behaves as a
spar scale.
System designers can choose between specially formulated adhesive tape or
mechanical clips to suit mounting requirements. Both mounting methods allow for
independent thermal expansion to that of the substrate.

RSLM / E / R / C 20µm - Stainless Steel scale
|
|
The following 16 digit alpha-numeric codes describe the scale.
|
|
RSLR = No reference mark;
RSLM = ref mark at midpoint;
RSLE = ref mark close to end of scale (see comments), not available for length < 80 mm.
|
|
RSLC = selectable ref mark every 200 mm (magnetic selector
maybe required - A-9653-0143). Not available for
lengths <280 mm.
|
|
Some part numbers will need to be added to the system, which
adds 2-3 weeks to the lead time for the initial order.
|
|
All scale lengths up to 1 metre are supplied with required
length of adhesive backing tape. For scale lengths over 1 metre the customer
will be supplied with a 5 metre roll of adhesive backing tape.
|
|
NOTE: Offering special
low prices for 5 length of RSLCs, with shorter lead time.

reference mark positions:
RSLE scales can be ordered with the reference mark either 20 mm (A option,
A-9683-xxxx) or 70 mm (B option, A-9689-xxxx) from the scale end. The A
option should only be used with 10 mm limit markers.
