Product ReleaseMICRONOR’S New MR121 ZapFREE Encoder Cable Solves Ground Loop and Interference Problems and Extends Reach Between Controller and Encoder Micronor’s new MR121 Encoder Cable is guaranteed to solve nagging ground loop and interference problems in motion control systems. The product uses Micronor’s ZapFREE technology which employs the use of fiber optic technology within the cable assembly, but in a manner completely transparent to the user. The MR121 product looks and functions like a standard electrical encoder cable. The equipment operator simply disconnects the existing controller-to-sensor connections and replaces them with corresponding MR121 ZapFREE Encoder Cables. No engineering redesign is required or needed.Micronor’s MR121 ZapFREE technology (patent applied for) provides transport of all controller-encoder signals from cable end-to-end via industry-standard 12-pole M23 electrical connectors found on popular encoders. The encoder’s A, B and M outputs (either single-pole or differential line driver formats) are internally converted from electrical-to-optical (E/O) on the encoder end, transported through optical fibers within the cable, and then converted back from optical-to-electrical (O/E) at the controller end. Controller-sourced shield, power, ground and power/ground sense paths are transported electrically Internal O/E and E/O converters require minimal current and a small regulated tap provides all internal power power requirements of the interfaces. Besides optical fiber’s natural resistance to EMI/RFI, ZapFREE takes advantage of fiber’s exceedingly low loss over distance. Low transmission loss allows separation of controller and a remote sensor to distances exceeding 3000 feet (1000 meters). MR121 ZapFREE Encoder Cables are made to order and any length. ZapFREE Encoder Cables are turn-key solutions for troublesome controller-sensor connections found in many heavy duty industrial and harsh environment applications; including plant machinery, robotic manufacturing systems, machine centers, elevators, conveyor belts, mining/drilling, radar antennae and transportation.

Micronor’s new MR314 ZapFREE™ High Resolution Fiber Optic Rotary Encoder was designed for large drive and rotary shaft applications requiring EMI immunity, higher resolution (1024ppr) and the mounting convenience of a traditional hollow shaft encoder package. There are no integral electronics within the encoder housing and the all-optical design requires just a single optical fiber connection – the utmost in simplicity, reliability and ease of installation. The MR314’s totally passive design outperforms conventional optical and magnetic rotary encoders over a wide range of harsh and/or hazardous environments: wide extended operating range (-60°C/+150°C); outdistances copper cable; intrinsically safe and ATEX-compliant; immune to EMI/RFI and ground loops; unaffected by high magnetic fields; and radiation resistant. Special versions can be easily engineered for thermal-vac environments.
This new Micronor product provides a simple and inexpensive solution for automating existing systems controlled by manually-operated potentiometers, rheostats or rotary cam switches. Motor Pots may not seem like a sexy control product but they fulfill a wonderful niche in process control! They are simple to use and easy to set up. No computers required or software to write. Easy to maintain and never obsolete. The user-specified potentiometers provide absolute positional feedback information or function as a variable resistor in an analog control or bridge circuit. The motor pot provides a smooth uniform ramp throughout its timing cycle. Rotary limit switches are programmed (via cams) to electrically control events (or provide status) at pre-stages. A few common applications include ramping up the field current of a DC motor or controlling the start-up of a generator.
Micronor’s MR310 ZapFREE Remote Encoder Interface (REI) Module is the system interface end of the ZapFREE Fiber Optic Rotary Encoder system – for motion control applications in harsh and hazardous environments.
Micronor’s new MR312 ZapFree Incremental Rotary Encoder (patent pending) is the world’s first commercially-available, entirely passive encoder for rotation sensing applications. There are no integral electronics within the encoder housing and the all-optical design requires just a single optical fiber connection – the utmost in simplicity, reliability and ease of installation. The MR312 offers immunity to lightning and atmospheric static that would “zap” conventional encoders; outdistances copper cable by allowing link lengths to 1000 meters (3280 feet); its inert nature proves ideal for use in hazardous and explosive environments; and its intrinsic EMI/RFI resistance allows for safe and reliable operation in and around medical equipment and other “noisy” industrial environments.
