Product catalog summary

Overview: The SpinCo Incremental Magnetic Encoder System is engineered for high-speed machine tool spindles, delivering precise position and speed feedback. It consists of a readhead and a magnetic ring, employing AMR and GMR sensor technologies for accurate functionality.

Key Features:

Capable of operating at speeds up to 55,000 rpm.
Provides 50 to 556 sin/cos periods per revolution.
Delivers ABZ digital incremental outputs with up to 4,096 steps per sin/cos period.
Includes analogue output signals (1 Vpp) and IP67 protection.
Compact readhead size with high accuracy.

General Information: The encoder system continuously calibrates signals for reliable output. The magnetic ring, made of elastoferrite and stainless steel, is protected by a welded cover foil and supports diameters from 31 mm to 176 mm. Installation methods include shrinkage press fitting, press fitting, gluing, or fasteners.

Storage and Handling: Components are packed in antistatic packaging. The readhead is ESD sensitive, and the magnetic ring should not be exposed to magnetic fields over 25 mT. Proper handling is essential to prevent damage.

Installation: Offers multiple readhead configurations and installation methods, such as press-fitting, fasteners, and gluing. Installation tolerances are specified for optimal performance.

Technical Specifications:

System data includes pole lengths of 1 mm or 2 mm, with less than 1 electrical degree of hysteresis.
Electrical data specifies a supply voltage of 5 V ±10% and a current consumption of less than 50 mA.
Environmental data covers operating temperatures from -40 °C to +85 °C and IP67 sealing.

Electrical Connections: Offers various connector options with detailed pin configurations for power and signal connections. Includes an automatic gain control (AGC) to maintain signal amplitude.

Maximum Speed: Provides a method to calculate edge separation for high-speed operation, ensuring error-free performance.

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 effects...

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 fields...
