Micronor's latest CANbus encoder sets new standards for compact size in this sector.
Micronor's latest CANbus encoder sets new standards for compact size in this sector.
At just 36mm diameter, the tiny ENA 36M will offer the advantages of the CANopen interface standard to even more applications.
The multiturn device comes in an IP67 stainless-steel case and can handle 3000rev/min to 12bit resolution.
Its cost is impressively competitive.
The CAN (Controller Area Network) serial bus system was originally developed for automotive applications in the early 1980s.
The CAN protocol was internationally standardised in 1993 as ISO11898-1 and is now supported by around 40 semiconductor manufacturers in hardware.
It provides a multiple-master hierarchy, which allows building intelligent and redundant systems.
If one network node is defect the network is still able to operate.
A sender of information transmits to all devices on the bus, so all receiving devices read the message and then decide if it is relevant to them.
This guarantees data integrity as all devices in the system use the same information.
There are also sophisticated error detecting mechanisms and retransmission of faulty messages, which guarantees data integrity.
