measurement principleMaintenance- and wear-free operation due to non-con-
tact measurement of rotationSuitable for ferromagnetic target wheels Safe detection of slow rotation from 0 Hz without pulse
loss and for high-speed rotation up to 25 kHzTwo channels shifted by 90º provide the direction of ro-
tationRobust and compact stainless steel housing suitable for
harsh applicationConstant duty output signals Customized cable fittings
Features
Modul target wheel 1.00 to 3.50 Measuring range 0 Hz to 25 kHz Temperature range -40 to +120 ºC Protection class IP 68 Type testing according to EN 50155
Advantages

disturbancesCable break monitoring by current output or voltage out-
put with standstill voltageMaintenance-free due to significant measuring distance
(air gap up to 3 mm)
Fields of application
Rail vehicles
- Traction control
- Anti-slip

Signal pattern
Explanation | |
x- | = voltage output |
xI | = current output |
xL | = voltage output (low current)(1) |
xM | = voltage output (standstill voltage) |
1, 2 | = channel 1, channel 2 |
̅1, ̅2 | = inverse channel 1, inverse channel 2 |
= galvanically isolated | |
VS | = supply voltage |
Signal level
When using the current output, the resistor to be connected must not exceed a specific value:
RB,max = (VS– 4 V) / Imax
with VS = 10 to 20 V DC and Imax = 16 mA
Example for VS = 15 V:
RB,max = 11 V / 16 mA = 690 Ω
