Passive encoder survives hostile environments
The MR312 ZapFree incremental rotary encoder (patent pending) is the world's first commercially available, entirely passive encoder for rotation sensing applications.
Interface sends encoder signals a kilometre
Micronor's MR310 ZapFree remote encoder interface module allows the all-optical, totally passive MR312/MR314 ZapFree fibre optic rotary encoders to remotely operate up to 1km away.
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 pending) 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 fibres 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 requirements of the interfaces.
Besides optical fibre's natural resistance to EMI/RFI, ZapFree takes advantage of fibre's exceedingly low loss over distance.
Low transmission loss allows separation of controller and a remote sensor to distances exceeding 1km.
Short or long, Micronor MR121 series ZapFree encoder cables are turnkey solutions for troublesome controller-sensor connections found in many heavy duty industrial and other harsh environment applications; including plant machinery, robotic manufacturing systems, machine centres, elevators, conveyor belts, mining/drilling, radar antennas and transportation.
MR121 ZapFree encoder cables are made to order and any length from 3m to 1km - with other connector options also available.
A typical 15m cable would be $589 each in quantities of 100. Request a free brochure from Micronor ...
