4 Product description
The inductive encoders of the RI360-QR24 series measure speeds and angle movements of up
to 360º. The sensor and the positioning element of the encoders are fully encapsulated and
designed as two independent and sealed units with protection to IP68/IP69K and contactless
operation. The optionally available adapter sleeves and mounting elements enable either the
front or the rear of the encoder sensor to be fitted to shafts with a diameter of up to 20 mm.
A mounting element for mounting on large rotatable machine parts is also provided in the pro-
gram.
The devices are available as absolute encoders with different output variants and also as
incremental encoders. A robust stainless steel EQR24 variant is available for use in the food and
beverage industry.
The QR24 encoders can be connected via a standard 8-pin male connector.

4.3 Operating principle
The QR24 encoders have contactless operation based on the inductive resonant circuit measur-
ing principle. This measuring principle makes it possible to design a fully encapsulated sensor
housing without seals, which is separated from the positioning element. Magnetic fields cannot
disturb the measuring process since 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. The inductive measuring principle of the QR24 encoder is absolute.
The inductive measuring principle of the QR24 encoder is absolute. To generate an incremental
output signal from the absolute rotation angle, the sensor detects the actual rotation angle per
millisecond and from this calculates the resulting number of pulses to be output.
4.4 Functions and operating modes
4.4.1 Output function
The devices are provided with an SSI interface according to the RS422 standard. The process
value is transmitted digitally via the interface either directly to the higher-level controller (with
an SSI card) directly or to a fieldbus device. The SSI interface can also transmit diagnostic bits in
the SSI telegram in addition to the process data. In an SSI transmission, the master sets a clock
signal by which the sensor responds in synchronization with the SSI telegram. The clock rate
and data frame lengths can be adjusted and are set by the master. The recommended clock
rate depends on the length of the connection cable.
The following tables describe the parameters and timings of the Turck SSI interface:

Dout dU min. Minimum output voltage at

> 2.3 V
Dout dU max. Maximum output voltage < 3.5 V
4.4.2 Update mode
The RI…-QR24…-HESG25… devices can be operated in synchronous or asynchronous update
mode. The operating modes can be changed via the Teach function. Asynchronous mode is
factory set. The synchronous update mode is not available for RI…-QR24…-HESG13 devices.
Asynchronous update mode
The clock signal rate of the controller sets the frequency for reading the position data. The
sensor transmits one position data bit to the controller with each pulse. The first clock pulse
edge of the controller indicates to the sensor to carry out a new position measurement. The
updated position data is transferred in the next read cycle.
NOTE
In asynchronous mode, the position data available for the controller is no more than
one update cycle old.
Synchronous update mode
The sensor synchronizes itself with the clock signal of the controller. The device starts position
measuring in time, before the next query is started by the controller. This reduces the contour-
ing error, but causes a precise scan pause (controller update) between two position queries of
the controller.

4.5.4 Encoders – protecting rings and mounting sets for QR24/EQR24 device types
Different mounting sets are required for different mounting types (see section “Installing”).
Each mounting set contains an aluminum protecting ring and an aluminum shielding plate.
The shielding plates enable the quality of the signal between the positioning element and the
sensor to be increased depending on mounting type and application. The protecting rings are
also available individually in aluminum and plastic.
