Speed sensors of type FA5 are non-contacting 2-channel hall effect encoders with a stainless-steel sensor tube. This solution has been established on the market for a long time and has proven to be very effective in a wide range of applications.

The sensors are available with various output signals:

Type	Measuring principle	Output signals
FAHZ5	Difference-Hall	2 square wave signals, Q2 to Q1 by 90° phase shift
FAHS5	Difference-Hall	2 square wave signals, Q2 to Q1 90° phase shift, 1 status signal for rotational direction detection
FAHD5	Difference-Hall	2 square wave signals, Q2 to Q1 90° phase shift, signals galvanically isolated
FAHQ5	Difference-Hall	4 square wave signals, Q2 to Q1 90° phase shift, Q1_N and Q2N are inverted signals of Q1 and Q2

Supply voltage U_B	9 ... 32 VDC
Frequency range	0.2 ... 20,000 Hz
Measuring channels	According to the type: 2 measuring channels 2 galvanically isolated measuring channels 2 measuring channels plus status channel rotational direction
