Product catalog summary
Overview: The document details the specifications and features of the TKN single and multiturn rotary encoder construction set with a CANopen interface, produced by TWK-ELEKTRONIK GmbH. It includes design, function, technical data, and connection details.
Design and Function: The encoder uses a Hall sensor for angular position recording and signal processing. It can output both position and speed signals. The device connects to a CANopen network and complies with CiA Draft Standards 301 and 406, and DSP 305. The multiturn version records revolutions in a counter, retaining position data even when power is off.
Key Features:
  • Contactless, wear-free sensor system based on the Hall principle.
  • Resolution of 4096 steps per 360° (12-bit).
  • Operating temperature range from -40°C to +85°C.
  • CANopen interface with various modes and emergency messaging capabilities.
Technical Data:
  • Output data includes position (2 or 4 bytes) and optional speed (2 bytes).
  • Programmable parameters include code direction, resolution, total steps, reference value, and gate time.
  • Electrical specifications include a voltage range of +17 VDC to +26 VDC and a typical operating current of 70 mA.
  • Mechanical data specifies a maximum rotation speed of 10000 min-1 for multiturn and singleturn versions without speed signal.
  • Environmental resistance to shock and vibration is specified according to DIN standards.
Connection and Installation: The encoder can be connected via a 5-pin screw clamp or PTFE pigtail connectors. The document includes diagrams illustrating the principle circuit and CANopen data profiles. Installation recommendations for the position magnet are provided, highlighting the impact of axial and radial offsets on linearity.
Ordering Information: The document outlines the order number structure, detailing options for electrical and mechanical variants, interface type, and resolution. Accessories such as additional position magnets and magnetic hubs are also listed.

Rotary encoder TKN46-1

Single and multiturn rotary encoder construction set TKN with CANopen interface Contactless, wear-free sensor system according to the Hall principle CANopen interface according to CiA, Device Profile for Encoders DS 406 Model TKN: construction set consisting of printed circuit board and magnet Single or multiturn versions (up to 4096 revolutions) Optionally with speed signal Other PCB types are possible on request CANopen features Recording of the angular position by means of a Hall sensor and signal processing including generation of the output signal - in addition to the angular position, a speed signal can also be output in digits / time unit - electrical connection via screw clamp (5-pin, conductor cross-section max. 0.5 mm²) or PTFE pigtail connector, 300 mm long - a CAN controller at the output enables connection to the CANopen network. According to CANopen Application Layer and Communication Profile, CiA Draft Standard 301, Version 4.1 and according to Device Profile for Encoders CiA Draft Standard Proposal 406, Version 3.0 and CANopen Layer setting Services and Protocol (LSS), CiA DSP 305.  NMT master: No  NMT slave: Yes  Maximum boot-up: No  Minimum boot-up: Yes  COB ID distribution: Default, SDO  Node ID distribution: Via Index 2000 or LSS  No. of PDOs: 2 Tx  PDO modes: Sync, async, cyclic, acyclic  Variable PDO mapping: No  Emergency message: Yes  Heartbeat: Yes  Node guarding: No  No. of SDOs: 1 Rx / 1 Tx  Device profile: CiA DSP 406 version 3.0 In the multiturn version, the number of revolutions is recorded in a counter. The position value is saved on shutting off the supply voltage. In voltage-free condition, the position value is recorded on movement of the shaft in a range of ≤ ± 90°. Optionally, node guarding may also be implemented instead of the heartbeat. The details of the profile are exhaustively described in the TXN 11551 user manual. TWK-ELEKTRONIK GmbH Heinrichstrasse 85
