Dynapar HS35iQ Series Hollow-Shaft Encoder with PulseIQ™ Technology, 1024 PPR, 6-28 mm Bore, IP67 Sealing

The Dynapar HS35iQ Series hollow-shaft incremental encoder with 1024 PPR resolution combines optical sensing with integrated PulseIQ™ fault detection technology to enable proactive diagnostics and minimize equipment downtime. This encoder features a 1024 pulses-per-revolution output with two-channel quadrature (AB) format and optional index (Z) channel, suitable for precision motion control and position feedback applications across industrial automation, manufacturing, and heavy-duty environments. The hollow-shaft design accommodates bore sizes from 6 mm to 28 mm, eliminating the need for flexible couplings while reducing installation complexity and cost. Built for reliability, the unit withstands 400G shock loading, operates across a -40°C to +100°C temperature range, and offers IP67 environmental sealing, making it suitable for demanding mill and plant floor operations. The HS35iQ encoder integrates fault detection capabilities—including monitoring for supply voltage anomalies, cable integrity failures, shaft slip, overspeed conditions, electronic faults, and thermal stress—with status indication via onboard LEDs and optional direct PLC integration. Electrical specifications include 5–26 VDC input power (80 mA maximum) and output options ranging from 40 mA push-pull and differential line drivers to 100 mA high-power drivers, providing flexible integration into existing control architectures. The encoder supports maximum operating speeds to 6,000 RPM with vibration tolerance rated to 20G across 5–3,000 Hz, and features electrically isolated bore design for enhanced noise immunity in electrically noisy environments.
