nProtection from line-conducted interference in accordance with DIN ISO 7637-2 (SAE J
113-11)
nExtended temperature range
4.3 Operating principle
The QR20 miniature encoders have contactless operation based on the inductive resonant
circuit measuring principle. Measurement is immune to magnetic fields as the positioning
element is not based on a magnet but on an inductive coil system, through which the sensor
and the positioning element (resonator) can form an oscillation circuit. Sensor and positioning
element form an inductive measuring system. An induced voltage generates appropriate sig-
nals in the receiver coils of the sensor, depending on the location of the positioning element.
The signals are evaluated in the internal 16-bit processor of the sensor and output as analog
signals. The QR20 is an absolute encoder and outputs a unique analog value for every shaft
position.

Functions and operating modes
10 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4.4 Functions and operating modes
The devices are provided with an analog output (current or voltage). The device output
supplies an analog signal corresponding to the location of the positioning element.
4.4.1 Current output
The RI…-QR20…-LI… devices are provided with a current output that supplies a current signal
in the range of 4…20 mA, which corresponds to the location of the positioning element. If the
positioning element is not detected, for example due to damage to the shaft, the output signal
increases to a fault signal of 22mA. The following figures show the current signal of the devices
in relation to the particular angle ranges:

Commissioning
18 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
7 Commissioning
After connecting and switching on the power supply, the device is automatically ready for
operation.

V01.01 | 2022/03 19
8 Operation
8.1 LED indications
LED indication Meaning
Green Sensor power supply correct.
Green flashing Positioning element is within the measuring range with reduced
signal quality (e.g. gap too large).
Off Positioning element is not within the measuring range or no power
supply available.

Troubleshooting
20 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
9 Troubleshooting
The strength of the resonance coupling is indicated by an LED. Any faults are indicated via the
LEDs.
If the device does not function as expected, first check whether ambient interference is present.
If there is no ambient interference present, check the connections of the device for faults.
If there are no faults, there is a device malfunction. In this case, decommission the device and
replace it with a new device of the same type.
