Product catalog summary
Overview: The document provides technical specifications and details for the TRX 42 series of electro-magnetic encoders by TWK-ELEKTRONIK GmbH. These encoders are designed for robust applications in mechanical engineering, instrumentation, and outdoor environments. They feature absolute multiturn gearboxes and offer both digital and analogue interfaces.
Specifications:
  • Design: Compact and robust, available in seawater-resistant aluminum or stainless steel.
  • Resolution: 4096 positions per 360° (12 Bits), with an optional 13 Bits resolution.
  • Environmental Data: Operating temperature from -40°C to +85°C, storage temperature from -20°C to +60°C, shock resistance of 500 m/s², and vibration resistance from 10 Hz to 2000 Hz.
  • Protection Grades: IP 66 standard, IP 69K with optional potting.
Mechanical Data:
  • Operating Speed: Up to 1000 rpm, with an optional 10,000 rpm.
  • Torque: Operating torque ≤ 8 Ncm at 500 rpm, wind-up torque ≤ 4 Ncm.
  • Shaft Loads: Permissible axial and radial loads up to 250 N.
Electronic Interfaces:
  • TRE 42: Synchronous Serial Interface (SSI).
  • TRN 42: CANopen interface.
  • TRA 42: Analogue outputs (0-20 mA, 4-20 mA, 0-10 VDC, ±10 VDC).
Electrical Data:
  • Supply Voltage: +11 VDC to +28 VDC for TRE and TRN models, +18 VDC to +28 VDC for TRA model.
  • Output Code: Natural binary, with Gray code optional.
  • Measuring Range: Up to 4096 revolutions.
Functionality: The encoders convert absolute angle information into serial data, which is transmitted synchronously with a clock signal. This design minimizes data lines and enhances reliability.
CANopen Features: The TRN 42 model supports CANopen with features like NMT-Slave, emergency messages, and heartbeat. It adheres to CiA DSP 406 Version 3.0.
Analogue Outputs: The TRA 42 model provides analogue signals through a 12-bit D/A converter, with adjustable measuring ranges and signal sense.
Construction and Materials: The encoders are constructed with a two-chamber design to separate rotating components from electronic circuits, using materials like stainless steel and aluminum for durability.
Order Code Format: The document provides a detailed format for ordering different models and configurations, including material, interface type, and resolution.

xzriza Electro-magnetic Encoders Model TRE 42 Model TRE 42: Synchronous Serial Interface - 12 Function The absolute angle information derived by the encoder is converted into serial information by an internal parallel-serial converter and then transmitted to a receiving electronic circuit in synchronism with a clock. Important advantages are : Low number of data lines and high reliability. Maximum data transmission rate The date rate ist defined by the following factors: □ Clock frequency 1 MHz max up to 40 meters connection line □ Delay time of the overall electronics (between 40 and 150 meters)...

Electro-magnetic Encoders Model TRA 42 Functional description and adjustment modes The following parameters can be adjusted by the user in situ: Code sense, zero point, end point, preset value and default values, via the multi-functional entries MFP 0 and 1 (entry circuit E1). Before delivery the measuring range will be set at 0 to 3600 degree and the code sense increasing CW with view to the shaft end. The default value for the Preset value is the centre of the measuring range. Other values can be realized ex-work. The encoder will be supplied ex work with the default values. Table for multi-functional...
