TCW4
PRELIMINARY - MAGNETIC CANopen ABSOLUTE MULTI TURN MODULAR SENSORS, TCW4 RANGE
With its modular design, the TCW4 CANopen absolute multi-turn sensor offers maximum flexibility
when installing it.
Application fields : agriculture, construction, forestry vehicles, medical, solar panels…
Robustness and excellent resistance to shocks / vibrations.
Standard IP 67 protection (IP69K option).
Operating temperature range: -20°C to 85°C.
Magnetic technology.
Universal supply 5 to 30Vdc – CANopen interface.
Available resolution up to 12 bits per revolution.
Turn counting up to 16 bits.
Also available : analog, PWM and SSI outputs.
Standard cable output with SUBD9 connector.
STANDARD TCW4 DIMENSION
Advised mechanical working conditions (for optimal performances) :
- recommanded air gap: 0,5mm to 3mm (between magnet's and sensor's faces),
- recommanded parallelism : +/-1° (between magnet and sensor),
- Misalignment tolerance : +/-0,5mm (between magnet's and sensor's centers).
Shaft system with magnet to be ordered separately (cf specific data-sheet M9105).

ADAPTATION POSSIBILTY
BEI Sensors distinguishes itself by its flexible approach and ability to react to customers needs, with us no limit exists; we shall always
try to supply you the product offering the best solution to your specifications.
Modified mechanics: Precision prototypes units, small and medium size. Units that will match themselves exactly to your mechanical
configuration or to your dimensional constraints.
Specific shaft system: for example with integrated coupling.
Send us your subset: we can integrate our encoder into your subset and return you the complete assembly with the guarantee of
an optimal mounting.
Connection / Cable assemblies: On the whole range of our sensors a wide selection of electrical connections are possible.

ELECTRICAL DATA
* Nota : Internal data refresh rate
PROGRAMMABLE PARAMETERS
Resolution: defines the resolution per revolution (0 à 4 096).
Transmission speed : programmable from 10kBaud (1 000m) to 1 Mbaud (25 m) ; value per default : 20 Kbaud.
Address : defines the software address of the encoder on the bus (1 à 127, Value per default : id = 1).
Direction : defines the direction of count of the encoder.
RAX : define the value of the current position (stationnary shaft).
Cames : high and low limits.
COMMUNICATION MODES
Encoder configuration : Reading/Writing of the encoder objects dictionnary (SDO mode).
3 modes are available to interrogate the encoder position/speed :
CYCLIC mode : the encoder transmits its position in an asynchronous manner. The frequency of the transmission is defined by the
programmable cyclic timer register from 0 to 65 535 ms,
SYNCHRO mode : the encoder transmits its position on a synchronous demand by the master.
POOLING mode (Answer to a RTR signal) : the encoder only answers to a request.
CANOPEN CONNECTION, CABLE + DB9 CONNECTOR
Nota : Refer to the bus standards for the maximal derivation length.
