DATA SHEET SP3D01_07 Issue 7, 25th October 2023 SpinCoTM Incremental Magnetic Encoder System SPINDLE ENCODER SpinCo is an incremental magnetic encoder system designed for use as primary position and speed feedback sensor for machine tool spindles. HIGH SPEED It consists of two key elements, a readhead and a magnetic ring. RLS proven AMR and GMR sensor technologies are used for sensing magnetized pattern on the magnetic ring to ensure accurate and reliable operation over the entire operating range. ROBUST DESIGN Signal stability From 50 to 556 sin/cos periods per revolution ABZ digital incremental outputs with up to 4,096 steps per sin/cos period Wide installation tolerances Small readhead size Analogue output signals (1 Vpp) High accuracy INDUSTRIAL AUTOMATION HARSH ENVIRONMENT MOTOR CONTROL

General information The encoder continuously calibrates the sensed signals to ensure accurate and reliable output signals, which are reported as industry standard 1 Vpp analogue incremental signals. The magnetic ring consists of an elastoferrite layer firmly bonded to a stainless steel hub. The elastoferrite layer is magnetised with alternating magnetic poles. The poles can be 1 mm or 2 mm long. To ensure safety and reliability even at the highest rotational speeds, all magnetic rings have a fully welded cover foil. This thin steel layer protects the elastoferrite from damage and the...

Storage and handling Storage temperature Operating temperature ߌ High resistance to humidity HANDLE WITH CARE. This encoder system is a high performance metrology product and should be handled with the same care as any other precision instrument. The use of industrial tools such as hammers and chisels or exposure to strong magnets such as a magnetic base is unacceptable and carries the risk of irreparable damage to the product. The magnetic ring should not be exposed to magnetic field densities higher than 25 mT on its surface, as this can damage the ring. Exposure to external magnetic...

Dimensions and installation drawings Dimensions and tolerances are in mm. Magnetic ring surface markings (engraved) Magnetic ring markings include serial number, QR code, logo, part number and reference mark. They are engraved on the hub. The reference mark engraving can deviate from the actual position of the reference mark magnetization for ±5 °. The engraving is for orientation purposes only.
