LCA2 Absolute Magnetic Encoder
The LCA2 provides precise position and speed feedback for motion control systems.
Key features:
Non-contact magnetic measurement
Rugged stainless steel scale with chemical-resistant ferrite layer
Dual-track design:
• Incremental track: 2mm pole pitch (S-N)
• Absolute track: 13-bit PRBS code
Advanced sensing:
• Hall sensor array (absolute position)
• AMR sensor (incremental tracking)
Onboard MCU processes data for accurate positioning
Fast response electronics
Built-in diagnostics via serial interface and status LEDs
This robust design ensures reliable operation in industrial environments.
