Fiber Optic Encoder suits harsh and hazardous environments.
May 24, 2006 -
With resolution of 1,024 ppr, ZapFREE(TM) M314 Hollow Shaft Rotary Encoder accommodates needs of large drive applications. There are no integral electronics within encoder housing, and all-optical design requires single 62.5/125 mm optical fiber connection. Intrinsically safe encoder is insensitive to EMI and RFI, and immune to lightning and atmospheric static. Operating from -40 to +80°C, standard model can be used in medical equipment and noisy industrial environments.

Micronor's New MR314 High Resolution Hollow Shaft Fiber Optic Encoder for Harsh & Hazardous Environments
Micronor Inc. is proud to submit this press release announcing the new M314 ZapFREE(tm) High Resolution Hollow Shaft Fiber Optic Rotary encoder for harsh and hazardous environments. This new product was specifically designed to accomodate the needs of Large Drive applications where these critical issues converge - EMI immunity, need for higher resolution (1024ppr) and mounting convenience of a hollow shaft encoder package. The very nature of large AC/DC motor drive signals is that the high voltage, high current motor drive signals emit EMI. You can suppress EMI to reduce encoder feedback problems where conventional optical or magnetic rotary encoders are employed BUT YOU CAN NEVER ELIMINATE IT. The difference is that the MICRONOR FIBER OPTIC ENCODERS ARE ENTIRELY PASSIVE AND IMMUNE TO EMI.
MR314 ZapFREE(TM) Fiber Optic Rotary Encoder
The MR314 ZapFree(TM) High Resolution (1024ppr) Hollow Shaft Rotary Encoder is an entirely passive, fiber optic incremental rotary encoder - ideal for a wide range of harsh and hazardous environmental applications. There are no integral electronics
within the encoder housing and the all-optical design requires just a single 62.5/125 MM optical fiber connection - the utmost in simplicity, reliability and ease of installation.
Downstream, an MR310 Remote Encoder Interface (REI) module converts the optical signals to an array of standard electrical outputs (both quadrature and analog) for interfacing to conventional counters, PLCs or computer interface boards. An RS232/RS422/RS485 serial interface is also provided for ease of interface to computers and PCs.
Features
o 100% passive sensing design
o Intrinsically safe and inert for use in hazardous and explosive atmospheres
o Insensitive to EMI and RFI for use in and around medical equipment and "noisy" industrial environments
o Immune to lightning and atmospheric static that "zaps" conventional encoders
o Outdistances copper, link lengths to 1000m
o Standard model operates -40°C to +80 °C; Extended option covers -60°C to +150 °C
o Special versions can be engineered for radiation and thermal-vac environments Company Information: Name: Micronor Address: 3483 Old Conejo Rd., Suite 203 City: Newbury Park State: CA ZIP: 91320 Country: USA Phone: 805-499-0114 FAX: 805-499-6585 http://www.micronor-inc.com
