MAGNETIC PWM ABSOLUTE SINGLE TURN MODULAR SENSORS, ACW4 RANGE MAGNETIC PWM ABSOLUTE SINGLE TURN MODULAR SENSORS, ACW4 RANGE

 With its two-part design, the ACW4 PWM absolute single-turn sensor offers maximum flexibility when

installing it.

 Application fields : agriculture, construction, forestry vehicles, medical, solar panels…
 Robustness and excellent resistance t o shocks / vibrations.
 Standard IP 67 protection (IP69K option).
 Operating temperature range: -40°C to 85°C (-40..+125°C option).
 Magnetic technology.
 Supply 5 to 30Vdc – PWM output interface.
 Available resolution up to 12 bits per revolution.
 Also available : analog, CANopen and SSI outputs.
 Standard PVC or PUR cable output.

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 integ r ated 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.

MAGNETIC PWM ABSOLUTE SINGLE TURN MODULAR SENSORS, ACW4 RANGE

ELECTRICAL DATA

Power supply 5–30Vdc Introduction < 1 s
Comsumption without load < 40mA (at 24Vdc) Response time < 10 ms
Resolution 12 bits Sampling rate * 1 kHz
Accuracy ± 0.3 % >10kOhms (Voltage output)

Advised load

Repeatability ± 0.1 %

500Ohms (current output)

* Nota : Internal data refresh rate

PWM

Ou

r PWM mode is defined with the following char acte rist ic s :
Supply : 5 to 30Vdc
PWM frequency : 1kHz

High time = Period x Duty Cycle

Period

Duty cycle : 10 to 90% (special duty cycle range on demand,

for example 5% to 95%, consult us)

Output voltage : Minimum high level = V cc- 2, 5Vd c.
PWM output is sub m it ted neither to the dela y error Er nor to the a n gular range extremities distorsion previou s ly presented.
As encoders with numeric communication do, PWM absolute encoders fit in various applications where speed is significant as well as

where there are a lot of electric interferences : unstable subsequent circuitry supply, distance between sensor and subsequent circuitry…
Because encoder’s data are not contained in a voltage level but in a time, data are prevented from interferences.
