Incremental encoders are used in machines and plants in different resolutions. Due to simple technology, incremental encoders can be realized with less cost than absolute encoders. On the other hand, they detect position changes only and need power supply to detect movement.
Our universal encoder in 58 mm housing is available with a wide range of hardware determined resolutions and in a fully programmable execution. Beside this standard, we provide plenty of different sizes. By combining different shaft geometries (solid, blind and hollow shaft) with available flange types, you easily find the perfect fit encoder for the mechanics of your machine.
Safe detection of rotation speed, rotation direction or standstill is provided by safety certified incremental encoders by TR-Electronic. Certified for applications with demands up to SIL 3, they provide operation modes as SLS, SOS, SSR, SDI or SSM with suitable safety appliance.
Additionally, we provide several different housing options for ATEX surroundings, for heavy duty applications with high mechanical loads or in aggressive media.
SIL rotary encoders
The solution doesn‘t always have to be a big one. An
incremental rotary encoder is sufficient for the safe detection
of speed, direction of rotation or standstill. The use of
certified components considerably facilitates validation of
the complete application. TR-Electronic therefore offers the
safety-certified incremental rotary encoder IE58+FS. The
user can choose between square-wave signals (with TTL or
HTL level) and sine-cosine interface. The rotary encoder is
certified for applications up to SIL 3 or PLe depending on
the chosen interface and safety module. The rotary encoder
permits the operating modes SLS, SOS SSR, SDI and SSM in
conjunction with an appropriate safety module.
This is partly due to the fact that the transmission channel
can be checked by means of a simple calculation from the
signal: The following must apply at any time: Sin²(t)+Cos²(t)
= 1. If the calculated value differs, the safety module can
go into a safe status. Another component of this high
safety classification is the simple design with proven optical
scanning with fixed resolution on the glass disk. 1024, 2048

and 4096 periods per revolution and a zero pulse may be
selected. The signal paths are designed differentially. As a
result the signal is immune to disturbance and failure of
a driver can be reliably detected. The incremental rotary
encoder is connected to the driving axis either with a solid
shaft, blind shaft (IS58+FS) or a hollow shaft (IH58+FS).
The form closure necessary for reliable measurement is
implemented through a groove in the shaft - in the case of
solid-shaft rotary encoders the appropriate spring is included
in the scope of supply.
Incremental Encoders - Family I_ _ 58 - Housing 58 mm
Our programmable incremental rotary encoders offer the
optimal basis for every requirement and are available with
solid shaft, continuous hollow shaft, blind shaft or integrated
coupling. You adapt the resolution of our programmable incremental
rotary encoders (size 58 mm) via software to meet
your demands.
The new generation I__58:2 has wide range input of 4,5..32
V DC and number of periods per turn up to 65,536. Additionally,
it provides hollow and blind shaft diameters up to 15
mm resp. ½”.
Incremental Rotary - Family I_H110 - Housing 110 mm
Programmable incremental encoders from family 110 fit big
shaft diameters of up to 50 mm. You adapt the resolution of
our programmable incremental rotary encoders via software
to meet your demands.
Depending on the required resolution, IEH 110 with up to
8192 steps per turn or IOH 110 with up to 36,000 steps per
turn fit your needs.
Incremental Rotary Encoders - Resolution Factory Set
Our incremental rotary encoders with resolution
preconfigured in the factory can be used in all applications
which require the basic functions of incremental position
detection.
The resolution of these incremental rotary encoders is set
ex-factory by fitting a code disk with a defined number of
lines respectively programming the detection electronic
with the requested number of lines. These incremental
rotary encoders are available in different sizes from 24 mm
- 130 mm. Of course they are also available with different
mechanical connections such as solid shaft, continuous
hollow shaft, blind shaft or integrated coupling.
Incremental rotary encoders – I_58+FS - Housing 58 mm
For applications that require a safety classification according
SIL / PL, TR-Electronic provides the safety certified incremental
encoder IE58-FS. The user can choose between squarewave
signals (with TTL or HTL level) and sine-cosine interface.
The rotary encoder is certified for applications with SIL 3 or
PLe (dependingon used safety module). The rotary encoder
permits the operating modes SLS, SOS SSR, SDI and SSM in
conjunction with an appropriate safety module.
The encoders are not programmable; the resolution is provided
safely and long term stable by the coded glass disk. 1024,
2048 and 4096 periods per revolution and a zero pulse may
be selected. The signal paths are designed differentially. As
