Shaft and ange
Robust shaft sealing veried for IP66. O-ring for tight seal-
ing of the hollow shaft to its mating shaft. Hollow shafts for
xing with an axial screw. Shaft dimensions: Ø12 mm, Ø16
mm, Ø17 mm taper. Solid shaft Ø 11 mm with key nut, and
B10 Euro ange, for xing with a shaft coupling.
Through-going hollow shaft with dimensions Ø 25 mm or
Ø 1 inch.
Enclosure
Robust cover with ingress protection class IP67 for protec-
tion against dust and liquids. Veried for use in salt water
environments.
Model available with ATEX/IECEx certication for hazardous
environments.
Bearings
Insulated peek insert to protect the bearings from shaft
currents. Model available with ceramic bearings for
increased insulation and prolonged lifetime.
Heavy duty bearings allow the encoder to be placed in the
most demanding environments, where it can be subjected
to shock and vibrations daily without losing quality or
accuracy.
Shock, vibrations, and temperature resistance
High accuracy code discs and robust electronics veried
for powerful shocks, vibrations, and extreme temperatures.
Protected against electronic interference
Short-circuit protection and polarity protection as
standard.
Overvoltage protection for protection against voltage
peaks on the supply, for example due to lightning strokes.
Earthing strap to conduct currents away from the encoder
cover.
Stable and easy mounting
Torque bracket available in a variety of orientations, for
xing of the torque arm.
Separate back cover for connection of cable wires to screw
terminals.
Ample space for easy handling when connecting the
cables.
M23 connector or pre-mounted cable with or without ying
connector available.

Quality into every detail
Note that some features described in this overview may only be available on certain models.
Output signals
Square wave signal output with 6 channels for dierential
transmission and reference pulse for relative position.
Available with a big number of output signals according to
market standards, like HTL, TTL, RS422, or 1 Vpp, as well as
High Current HTL for transmission over long cables.
Dual output models are available, with double scanning
sensors and two galvanically insulated electronic circuits.
The dual output signals can be used in two separate
systems for dierent functions, or for achieving redundant
signals.
Resolution
Wide range of dierent pulse rates available from 1 to
10 000 ppr.
Data and encoder diagnostics
Leine Linde’s ADS solutions are advanced diagnostic sys-
tems, built into the encoder, enabling condition
monitoring and predicitive maintenance. ADS monitors
the encoder functions as well as parameters like vibration
and temperature in the motor installation.
Programmable speed switch
The 800 series can be bought with Overspeed, which is the
Leine Linde speed switch solution with four programmable
relays for the settings of your choice.
Relevant certications
Models available certied for use in hazardous areas,
ATEX/IECEx zone 1/21, or 2/22. Functional safety certied
encoders available up to risk level SIL2, PLd, category 3.

Mechanics
This page oers an overview of the dierent models in the 800 series. Each model is
available in several dierent variants when it comes to shafts, anges, resolutions,
electronics and connections. Please consult the code keys on pages 14-21 for detailed
overview of all options.
Model 850
Solid shaft encoder with B10 Euro ange.
Model 855
Dual solid shaft encoder with B10 Euro ange. Redundant scanning sensors and two
separate electronic circuits with galvanically insulated outputs.
