± 10, ± 5, ± 3 µm/m accuracy grades

The LMBA-1100/2100 stainless steel measuring scale is installed using a double-sided adhesive tape with release paper for direct application to the mounting surface.

Scale type LMBA-1110 is for lengths to 9200 mm and scale type LMBA-2110 is for lengths greater than 9200 mm to 32 meters.

± 10, ± 5, ± 3 µm/m accuracy grades

The LMBA-1410/2410 measuring scale is designed for fluid flooded environments or where the mounting surface is either segmented or not of a matching CTE. Slim stainless steel spars are first mechanically attached to the machine bed with screws then a full-length stainless steel grating scale is mounted and held in position with a “snap cover” strip.

IP-67 Rated

The LMKA-11100 / LMKA-21100 is an open, non-contact scanning head with integrated signal conditioning electronics. It can be combined with measuring scales LMBA-1110/2110 or LMBA-1410/2410.

Direct output of Drive CLiQ, EnDat 2.2, Fanuc, Biss C, Mitsubishi or SSI serial communications.

The LMFA 1310/2310 Measuring rail is a size 20 mm profile rail bearing with an absolute measuring scale integrated into the top surface using a “snap cover” strip. The measuring rail is available in a single section to 3940mm. Longer lengths (to 32 M) utilize multiple rail sections with a full-length absolute measuring scale. Ideal for long bed segmented machine tools and machine tool retrofits.

IP-67 Rated

The LMKA-1310x/2310x scanning head is guided precisely by the matching LMFA bearing guided measuring scale for assured sensor alignment without difficulty. The sensor is integrated into the bearing carriage and the scanning head contains all signal conditioning electronics for direct output of Drive CLiQ, EnDat 2.2, Fanuc, Biss C, Mitsubishi or SSI serial communications. A flexible coupling (rigid in the direction of travel) connects the scanning head to the machine and absorbs lateral mechanical deviations of non-parallel machine motion.

Absolute Encoder Catalog

The AMOSIN absolute linear measuring systems consist of a stainless steel inductive Grating Scale and a non-contact electronic Reader Head. With an IP-67 rating and inductive sensor technology, they have high tolerance to many industrial contaminants. These encoders can be employed in both clean and polluted environments.

The AMOSIN absolute linear measuring systems deliver high-performance position feedback that is suitable for closed loop motion control either as the primary encoder (direct drive linear motor) or as the secondary encoder in a ball screw driven axis. They are of value in general for drives where high dynamic range and stiffness is required. The environmental attributes of the AMOSIN design are similar to that of magnetic encoders but they are not magnetic. Neither the grating scale nor the reading head are harmed by direct contact to a magnet. Unlike magnetic encoders they exhibit no hysteresis (backlash) of motion and can operate in close proximity to direct drive motors.

Unlike magnetic encoders they exhibit no hysteresis (backlash) of motion and can operate in close proximity to direct drive motors.

The Grating Scales can be applied directly to the mounting surface with a dual sided adhesive tape or integrated into a screwed stainless steel spar system with a snap cover that locks the scale tape into the spar without any adhesives. Linear scales are available to 32 meter lengths in three different accuracy classes. The absolute linear gratings are produced, using a precision etched photo-lithographic process, with two highly accurate grating tracks – one incremental and the other a coded absolute pattern.

The Reader Head incorporates micro coil array sensors and includes both analog and digital evaluation electronics The absolute position value is acquired in real time without either hysteresis or significant periodic error. Several types of serial interfaces are available, including Drive CLiQ, EnDAt 2.2, Fanuc, Biss C, Mitsubishi and SSI. As an option, the system electronics can also deliver 1 Vpp SINE /COSINE signals with a 40µm period. All absolute linear encoder heads have a high degree of immunity to contamination due to their IP-67 rating and inductive sensor technology. Grease, oil, coolant, dust and dirt have no deleterious effect on the read head function.

Typical absolute linear measuring system applications include:

Machine Tools
Water, Laser and Plasma cutting machines
Sheet Metal Forming
Factory Automation
Linear Actuators and Stages
Metrology and Gaging
SMT Pick and Place machines
