H10045 Frequently Asked Questions

What is the difference between H10045-01 and H10045-02?

H10045-01 uses a keyed connection where the shaft engages with a keyway on the motor shaft, providing slip-resistant power transmission ideal for high-torque applications. H10045-02 uses a locking ring fixation that clamps onto the motor shaft without a keyway, simplifying installation and removal.

Can the H10045 be used with PLC systems?

Yes. The H10045 outputs A/B/Z differential RS422 signals, which are compatible with most PLCs and motion controllers. The K-type (RS422 line driver) output is recommended for long-distance transmission or noisy industrial environments.

What supply voltage does the H10045 require?

The H10045 supports two voltage ranges: DC 5V±0.25V (for L-type TTL output) and 5~26V wide voltage (for C/CP/F/K output types). Select the appropriate model based on your controller's voltage level.

What is the maximum cable length for the H10045?

With the K-type RS422 differential output, cable lengths up to 100 meters are achievable without signal degradation. For C/F/L-type outputs, cable length should be kept under 20 meters to maintain signal integrity.

Is the H10045 suitable for outdoor or wash-down environments?

The H10045 has an IP54 protection rating, making it suitable for environments with dust, oil splashes, and water spray. It is not recommended for submerged or high-pressure wash-down applications. For outdoor use, ensure proper cable entry sealing.
