Application
The Temposonics®sensor is used for measurement and conversion
of the length (position) variable in the fields of automated systems and
mechanical engineering.
Principle of operation and system construction
For position measurement, the absolute, linear Temposonics®position
sensors make use of the properties offered by the specially designed
magnetostrictive waveguide. Inside the sensor a torsional strain pulse
is induced in the waveguide by momentary interaction of two magnet-
ic fields. The interaction between these two magnetic fields produces
a strain pulse, which is detected by the converter at the sensor elec-
tronics housing. One field is produced by a moving position magnet,
which travels along the sensor rod with the waveguide inside. The oth-
er field is generated by a current pulse applied to the waveguide. The
position of the moving magnet is determined precisely by measuring
the time-of-flight between the application of the current pulse and the
arrival of the strain pulse at the sensor head. The result is a reliable
position measurement with high accuracy and repeatability.

Modular mechanical and electronic construction
• The sensor housing (rod/profile) protects the sensor element.
• The sensor electronics housing, a rugged aluminum/stainless steel
construction, contains the complete electronic interface with
active signal conditioning.
• The external position magnet is a permanent magnet. Mounted
on the mobile machine part, it travels along the sensing element
and triggers the measurement through the housing wall.
• Depending on the type, the sensor is connected to the controller
via a plug.
• The sensor can be connected directly to a control system.
Its electronics generates a strictly position-proportional signal
output between zero and end position.

Installation of EP
The position sensor can be installed in any position. Normally, the
sensor is firmly installed and the position magnet is fastened to
the mobile machine part. Thus it can travel along the sensor rod
contactlessly.
The sensor is fitted on a flat machine surface using mounting clamps
(Fig. 4). A length-dependent number of these clamps are delivered
with the sensor and must be distributed over the profile at regular
distances.
For fastening, we recommend using M5×20 screws according to
DIN 6912 that should be tightened with a maximum fastening torque
of 5 Nm.

NOTICE
Do not mount the sensors in the area of strong magnetic or electric
noise fields. Take care to mount the sensor in an axially parallel
position to avoid damaging the carriage, magnet and sensor rod.
The sensor is isolated from the machine ground. For this reason,
grouding via grounding lug on the sensor electronics housing is
indispensable (Fig. 5).

Installation of EH
The rod-style version has been developed for direct stroke
measurement in a fluid cylinder.
Mounted on the bottom of the piston, the ring magnet travels over
the rod contactlessly and marks the position exactly through the
rod wall – independent of the hydraulic fluid.
Hydraulics sealing
The sealing via a 15.3 × 2.2 O-ring in the undercut is possible (Fig. 9).
A screw hole based on ISO 6149-1 (Fig. 10) must be provided.
• The flange contact surface must be seated completely on the
cylinder mounting surface.
• The cylinder manufacturer determines the pressure-resistant gasket
(copper gasket, O-ring, etc.).
• The position magnet should not grind on the rod.
• The plunger borehole (Ø 10 mm rod: ≥ Ø 13 mm (≥ Ø 0.52 in.) /
Ø 7 mm rod: ≥ Ø 10 mm (≥ Ø 0.4 in.)) depends on the pressure
and piston speed.
• The peak pressure should not be exceeded.
• Protect the sensor rod from wear using suitable constructive
measures.

Mounting the U-magnet
Using a non-magnetizable mounting device is mandatory. The magnet
must not grind on the sensor rod. Alignment errors are compensated
via the air gap.
• Max. surface pressure: 40 N/mm2
• Max. fastening torque for M4 screws: 1 Nm; use washer,
if necessary
Large stroke lengths from 1 meter (39 in.)
Horizontally installed sensors should be supported mechanically
at the rod end. Longer rods require evenly distributed mechanical
support over the entire length. In this case (Fig. 13) the sensor rod
can be supported by fixing clips and an U-magnet can be used for
measurement.
NOTICE
A maximum permissible air gap of 3 mm (0.12 in.) must not be
exceeded.

4.6 Electrical connections
Placement of installation and cabling have vital influence on the sensor
EMC (electromagnetic compatibility). Hence correct installation of
this active electronic system and the EMC of the entire system must
be ensured by using suitable metal connectors, shielded cables
and grounding. Overvoltages or faulty connections can damage its
electronics despite protection against wrong polarity.
NOTICE
Never connect/disconnect the sensor when voltage is applied.
Instructions for connection
• Use low-resistance twisted pair and shielded cables and connect
the shield to ground externally via the controller equipment.
• Keep control and sign leads separate from power cables and
sufficiently far away from motor cables, frequency inverters,
valve lines, relays, etc.
• Use only connectors with metal housing and connect the shielding
to the connector housing.
• Keep the connection surface at both screening ends as large
as possible.
• Keep all non-shielded leads as short as possible.
• Keep the earth connection as short as possible with a large
cross section. Avoid ground loops.
• With potential differences between the ground connection of the
machine and the electronics, no compensating current flowing
over the shield is allowed. We recommend using an equipotential
bonding conductor with large cross-section or a cable with separate
dual shielding and connecting the shields only at one end.
• Use only stabilized power supplies and make sure that the specified
connecting values are met.
• Install potential compensating leads with large cross section, or use
cables with separate double shielding, and connect only one end of
the shield.
• Use only stabilized power supplies in compliance with the specified
connecting values.
NOTICE
The E-Series EP and EL sensors must be grounded via grounding
lug on the sensor electronics housing (Fig. 5).
Connection types
Connect the sensor directly to the control system, indicator or other
evaluating systems as follows:

CANopen bus interface
CANbus (Controller Area Network) is designed for high-speed data
exchange at machine level. CAN is a vendor independent open fieldbus
system, based on standard ISO 11898. CAN specifies the functional
and technical parameters with which the intelligent digital automation
devices can be networked via a master-slave serial link by using a
communication profile. Protocol architecture of functional and
applications data is oriented to the OSI reference model (ISO 7498).
Bus technology is administrated and developed by the user
organisation CiA (CAN in Automation).
5.1 Encoder functionality system description
Temposonics®sensors are linear transducers and are suitable for a
CANopen protocol network. That is a CAN based higher layer protocol.
The sensor can be used as a CAN bus slave in networks with the
CANopen data protocol (CiA Standard DS 301 V4.02), the encoder
profile DS 406 V3.1 and the LSS Service DS 305 V2.1.1.
The sensor is performing Class C2 functionality.
Network Management (NMT) – Slave
The NMT state machine defines the communication behavior of the
CANopen device.
Layer Setting Services (LSS) DS 305
Layer Setting Services (LSS) are used in order to configure the sensor
in terms of node ID and / or the baud rate. The sensor can be switched
to LSS configuration mode either globally or selectively.
Service Data Object (SDO)
SDO messages are used for reading and writing access to all entries
of the object dictionary. SDOs are used for device configuration in the
first place.
Identity objects
Identity including vendor ID, product code, revision number and
serial number.
Variable Process Data Object (PDO) mapping
The real-time data transfer of position, velocity and limit switch states
is performed by PDO messages. Data is transmitted within four
TPDO’s (transmit PDO) and each with a maximum 8 byte wide data
block. Variable PDO mapping can be configured via SDO messages.
Special Function Object (SFO) sync object
The sync object is broadcasted periodically by the synchronisation
device to all application devices. Synchronous PDOs will be
transmitted to the controller after receiving the sync message.
Emergency object
Emergency messages are triggered by the occurrence of a device
internal fatal error situation and are transmitted from the application
device concerned to the other devices with highest priority.
This makes them suitable for interrupting type error alerts.
Nodeguard object
The nodeguard object is used to monitor the whole network state.
The nodeguard object is sent cyclically to detect the sensor that the
controller works well. On a missing nodeguard object (i.e. controller
stopped) the sensor automaticly can stop PDO data transmission to
reduce the busload.
Heartbeat function
Instead of the node-guarding the heartbeat-function can be used.
The Producer-Heartbeat-Time defines the time frame in which
a new heartbeat message is sent.
Event timer
The event timer defines the asynchronous transmission period
for PDOs.
Encoder profile DS 406
Up to four work areas with upper and lower limits and corresponding
status register. Up to four cam switches with upper or lower threshold
level and status register
CANbus connection
The CANopen encoders are equipped with a bus trunk line in various
lengths and can be terminated in the device.
The devices do not have an integrated T-coupler nor they are looped
internally. If possible, drop lines should be avoided, as in principle they
lead to signal reflections. As a rule the reflections caused by the drop
lines are not critical, if they have completely decayed before the point
in time when the scanning occurs.
