R56 supports 56 C-Face or foot mounting.
Rotor and stator selection is treated as a matched assembly.

Cables, couplings and measuring wheels

Accessories connect the encoder with its mechanical installation and control input. Specify cable length, both connectors and pin assignment. A coupling needs both shaft diameters; a measuring wheel enquiry also needs the contact surface and the intended linear measurement arrangement.

CPL flexible couplings are listed in metric and inch sizes.
Encoder cables and cable assemblies support different output arrangements.
Measuring wheels convert linear movement into encoder rotation.
RIM SS2 is a signal splitter; RIM SSW is a signal switch.

RIM Tach components and upgrade kits

Pulse wheels, sensor modules and generation upgrade kits form separate supply items within the RIM Tach system. Identify the required component independently from the complete encoder. Attach its own marking, bore measurement and the designation of the assembly that will remain installed.

NSRT replacement wheels are listed for RT8 and RT1 families.
RIM Tach sensor modules form a separate component group.
Upgrade kits are available for NexGen RT8 and RT1 conversion.
Wheel bore, PPR and index configuration require individual identification.

Compact F18, E14 and E23 encoders

HDP30: 30 mm housing diameter.
HDN58: 58 mm housing diameter.
Incremental or absolute output follows the available configuration.

Define the feedback task

Begin with the machine function: speed feedback, angular position or linear measurement using a wheel. State whether the purchase covers a new device, a complete feedback assembly or a replacement component. Identify the motor, drive or controller that will use the signal.

Specify incremental or absolute measurement

An incremental enquiry should state the pulses per revolution, the required A/B channels and whether the index channel is used. Include the receiving input specification and the operating speed range. Keep the required pulse count distinct from any multiplication configured inside the controller.

For absolute feedback, state the interface, resolution and single-turn or multi-turn requirement. Attach the existing controller settings where applicable.

If the installation is new, describe the position information needed by the application and identify the proposed connection to the control system.

Match the electrical connection

Record the supply voltage, output circuit and receiving input from the equipment documentation. Include the complete pin assignment rather than relying on connector appearance.

Photograph the connector key, contact arrangement and cable entry so the proposed assembly can be checked against the installation.

Check the shaft and motor interface

Provide the shaft diameter, engagement length and fixing arrangement. Preserve inch dimensions in their original units and distinguish them from metric measurements. A hollow-shaft installation also needs the anti-rotation arrangement and the clearance around the encoder body and cable outlet.

Prepare the AI25 control information

Write the exact protocol and controller model in the specification. EtherNet/IP, EtherCAT, PROFINET and serial interface versions belong to different configurations.

Preserve the existing device description file, connection diagram and communication settings when replacing an installed encoder within a working control system.

Select the HS35iQ diagnostic arrangement

Identify whether a standard or programmable HS35iQ is required. For a programmable device, attach the intended configuration or existing settings. Specify how diagnostic information will be used and include the actual connector arrangement so the enquiry covers the relevant electrical connections.

For a replacement related to a diagnostic indication, record the indication and the conditions in which it appears. Include the motor, drive and cable identities.

Keep observed symptoms separate from confirmed measurements so equipment selection starts with an accurate description of the installed feedback chain.

Define the RIM Tach package

A complete RIM Tach enquiry should identify the motor interface, encoder generation, pulse wheel and sensor arrangement. When only one component is required, retain the identity of the assembly that stays installed.

Photograph the component marking and its mounting position before equipment is dismantled.

Specify a resolver assembly

Provide the resolver designation, electrical cycles, excitation voltage and frequency from the equipment documentation. Attach the converter model and connection diagram.

A frameless installation needs the rotor and stator drawings, mounting diameters and axial positioning within the motor or machine assembly.

State whether the enquiry covers a matched pair, a housed resolver or an assembly with mounting accessories. Preserve the winding and terminal identification shown in the original documentation.

For installed equipment, add the motor identity and photographs that connect the resolver to its actual operating location.

Separate the sensor and its accessories

For non-contact equipment, show the target magnet, sensor position and spacing on a section drawing. Identify the required output and control input. For a measuring wheel arrangement, describe the contact material and the installation that converts linear travel into rotation at the encoder.

Prepare the equipment supply enquiry

Send a position list containing the complete code, equipment function, quantity and supporting file references. For an existing machine, add its model and serial number. For new equipment, include the technical specification and installation drawing. Name photographs and documents by list position.

State the delivery destination, packaging and documentation requirements. Define complete equipment, replacement assemblies and additional accessories as separate supply items.

If installation or commissioning assistance is required, describe that scope separately from the hardware package so the enquiry can be evaluated against explicit requirements.

Availability, price, lead time, documents and compatibility are checked for the specific enquiry. This page does not establish official dealership or authorised service status; specifications apply to the named families and particular configurations.
