FIBER OPTIC ABSOLUTE ENCODER MR332 ZapFREE Fiber Optic Absolute Position Sensor ® MR330 SERIES The MR332 Series ZapFREE® Fiber Optic Absolute Position Sensor measures absolute angular position from 0° to 360° with 0.025° resolution. This innovative sensor system outdistances conventional absolute encoders and resolvers – transmitting interference-free up to 300 meters! The system consists of a passive optical sensor and active controller linked via industry standard 62.5/125μm multimode fiber. Interconnect options include commercial Duplex LC or industrial grade ODVA IP-LC Duplex. U.S. Patent 8,461,514 B1 Inherently Safe, Simple Mechanical Device EPL Mb/Gb/Gc/Db/Dc With Duplex LC Pigtail With ODVA IP-LC Interface 24 VDC, SSI, RS485, Modbus, USB, Analog, Digital Duplex LC, Multimode 62.5/125 Fiber Optic Cabling Features • 100% passive sensing design - no electronics whatsoever • Absolute 0.025° (14-bit) single-turn resolution • Controller can also track up to 4096 (12-bit) turns • EX Classified “Inherently Safe, Simple Mechanical Device”, i.e. sensor can be installed in all manner of hazardous location or explosive atmospheres: mines, gas or dust • Immune to EMI and RFI for safe use in and around medical equipment and “noisy” industrial environments • Immune to lightning and high voltages • Outdistances copper, link lengths to 300 meters • Standard model operates over -40°C to +80 °C • Special versions can be engineered for radiation
