ELGO Mix 4 series Magnetic Type
Encoder type: Non contact, magnetic, open type. Open scale linear encoders are used
primarily where environmental conditions are clean, dry and free of oils. The magnetic
encoder scale is susceptible to damage from magnetic fields. Great care should be taken
to isolate the magnetic scale from magnets, static electricity, and electrical current.
Mechanical design: Magnetic scale with stainless steel protective cover, magnetic
sensor unit, high flex twisted shielded cable. The magnetic linear encoder system
features an integrated sensor and translator with a one shot marker pulse output (Elgo
Mix 4). With the one shot marker pulse, the encoder can send a marker pulse once after
power–up when it passes the marker tape (maximum speed 0.1 m/second). Encoder is
bonded to the stage surface with a double sided industrial adhesive tape. (DO NOT
attempt to remove the scale from the stage surface, for this will permanently damage the
encoder scale. Contact Baldor or an authorized distributor for assistance).
Maintenance: The encoder scale can be cleaned with soapy water or alcohol. Avoid
chemicals such as acetone, MEK, and other solvents. The encoder magnetic scanning
unit should be treated with great care as not to scratch or mar the external read head
surface. If cleaning is required, the encoder read head surface can be cleaned with
soapy water or alcohol. (Avoid submersion). Using a cotton swab, lightly wipe clean the
contaminated surfaces. If removal of the encoder magnetic read head is required,
consult with Baldor or an authorized distributor.
