The TR Electronic CDH75M-00001 operates from a wide voltage supply range of 11 … 27 V DC for flexible system integration.

Furthermore, its no-load current consumption stays below 150 mA at 24 V DC to ensure low power usage.

Specifically, the main measurement system offers a high resolution of 25 bit with 8192 steps per revolution.

Moreover, it supports up to 4096 total revolutions to meet complex multi-turn positioning requirements.

Additionally, the device uses a binary code format for consistent and accurate data output.

This encoder is built with two redundant detection systems for reliable safety performance in critical applications.

Meanwhile, each system provides separate output signals and includes mutual microcontroller monitoring.

It uses a CRC-secured SSI protocol with life counter signals to ensure data integrity at all times.

Notably, the CDH75M-00001 achieves SIL 3 according to DIN EN 61508 and VDE 0803 standards.

It also meets PL e under EN ISO 13849, with a PFH value of 10×10⁻⁹ per hour for the complete system.

Cross validation and safety analysis must be performed within the higher-level controller for full compliance.

The unit is equipped with two independent SSI interfaces for secure and redundant signal transmission.

Each channel transfers position data, error bits, life counter values and CRC checks for reliable diagnostics.

Additionally, it provides an unsafe incremental interface with A, A-, B, B- signals in RS 422 format.

Specifically, this model is configured with 4096 steps per revolution as a fixed pulse count setting.

Optional sine/cosine or different pulse rates are available upon further customer request.

The CDH75M-00001 uses a hollow shaft design with a shaft size of 20 H7 including a 5 JS9 groove.

It features a flange-side attachment to prevent unwanted rotation during operation.

Mechanically, the encoder permits a maximum speed of 3000 min⁻¹ for standard operation.

Bearing life reaches at least 3.9×10¹⁰ revolutions under speeds up to 1500 min⁻¹.

Permissible angular acceleration is limited to 10⁴ rad/s² to protect internal components.

The typical total mass of the unit is approximately 1 kg, supporting easy mounting and integration.

This safety encoder offers a protection class of IP54 according to DIN EN 60529 for reliable use in industry.

Standard operating temperature ranges from 0 °C to +60 °C, with an optional -20 °C to +70 °C version.

Relative humidity can reach up to 98% as long as conditions remain non-condensing.

Storage temperature spans from -30 °C to +80 °C in a dry environment for long-term preservation.

Vibration resistance is rated up to 100 m/s² at 50–2000 Hz, and shock resistance up to 1000 m/s² for 11 ms.

It also meets emission class B for use in industrial environments with strict EMC requirements.

First, mount the encoder using its flange design and secure the anti-rotation fixture properly.

Ensure the hollow shaft is correctly fitted to the application shaft to avoid misalignment or stress.

Next, connect power and signal cables through the two supplied cable glands for stable wiring.

The unit includes a removable connection cap to simplify installation and maintenance procedures.

For signal output, use the RS 422 incremental interface and dual SSI channels as required by the control system.

Finally, verify all connections before powering on the system to prevent damage or incorrect readings.
