Rotary Sensor
touchless technology
transmissive
with 2 PNP switched
outputs
Series RFC4800
The RFC 4800 utilizes a
separate magnet or magnetic
position marker, attached to
the rotating shaft to be
measured.
The fully touchless transmissive
measurement through any nonferromagnetic material is an
advantage over shaft type
sensors.
The orientation of the magnetic
field is measured and an
analog voltage representing
the angle is the output signal.
Two PNP switch outputs are
available with fieldprogrammable angular
positions, replacing the function
of separate limit switches.
The two-part design, with the
RFC sensor itself, and its
magnetic position marker,
offers great flexibility when
mounting. The absence of
shaft and bearing makes the
assembly much less sensitive
to axial and radial application
tolerances. Measurements
can be made transmissively
through any non-ferromagnetic
material.
Special features
• fully touchless - no shaft or
seals to wear
• measure directly through any
non-ferromagnetic material
• electrical range up to 360°
• 4-20 mA current output and
2 additional programmabled
PNP switch outputs
• linearity ±0.5 %
• simple mounting
• large allowable radial offset
for magnetic pickup
• protection class IP67
• unlimited mechanical lifetime
• resolution 12 bit
• wide temperature range
-40°C up to +85°C
• for other analog or digital
interface versions, see
separate data sheet

The housing is made of high
grade temperature-resistant
plastic material. Elongated
holes allow for simple mounting
and easy mechanical adjustment. The sensor is totally
sealed and is not sensitive to
dust, dirt or moisture.
Electrical connection is made
via a shielded cable or lead
wires, or by optional M12
connector.
The two-state switched
outputs can be positioned by
the user anywhere within the
electrical range of the sensor.
Teach-In is accomplished
through the electrical cable.
The cable length for
programming can be up to
10 m. Programmed switch
positions are stored nonvolatile memory for at least
50 years.
Setting limits in multiple
sensors can be easily
accomplished by using the
Teach-In Box (Z-RFC-T01),
which offers easy eletrical
connection. The user is
guided by LEDs and programs
the sensor via push buttons.

Working distance A / magnet constant
Z-RFC-P01: A = 0 ... 1.5 mm / magnet constant = 1.85 [°/mm2]
Z-RFC-P02: A = 0 ... 4 mm / magnet constant = 0.8 [°/mm2]
(See separate position marker data sheet)
Lateral magnet offset
(Results in additional linearity error)
max. ±3 mm (Z-RFC-P02), max. ±1.5 mm (Z-RFC-P01)
The maximum additional linearity error due to lateral offset between sensor and position
marker may be approximated as follows:
Error [°] = magnet constant x ( offset [mm] )2
The magnet constant depends from the position marker.
Example: Z-RFC-P02: magnet constant = 0.8 °/mm2; offset = 0,5 mm
Error [°] = 0.8°/mm2 x (0.5 mm)2 = 0,2°
