OMRON H8PR-16 Rotary Positioner – 16-Position Cam Switch Timer | H8PR Series
The OMRON H8PR-16 is a precision rotary positioner designed for demanding industrial automation environments where accurate, repeatable cam-based switching is critical. As part of OMRON’s proven H8PR Series, this unit delivers 16 independently programmable cam positions, enabling engineers to orchestrate complex multi-step machine sequences with a single compact device.
Product Positioning: Targeted at OEM machine builders, panel integrators, and MRO procurement teams requiring a reliable, standards-compliant rotary cam switch timer with direct PLC interface compatibility. The H8PR-16 is the preferred choice when sequence density, wiring simplicity, and long service life are non-negotiable.

Engineering Advantages
- 16 Independent Cam Channels: Eliminates the need for multiple discrete timers, reducing panel footprint and wiring complexity.
- Solid-State Reliability: Electronic cam switching eliminates mechanical wear, extending MTBF versus traditional drum switches.
- Direct PLC Integration: Output signals are PLC-compatible; no signal conditioning required for Siemens, Mitsubishi, Allen-Bradley, or OMRON PLCs.
- Front-Panel Programming: Intuitive rotary dial and LED indicators allow on-site cam angle adjustment without laptop or software.
- Compact DIN-Rail Form Factor: Minimizes panel space while supporting high channel density.
System Architecture & Signal Flow
The H8PR-16 accepts a shaft encoder or resolver input representing the mechanical angle of the driven axis. Internally, the unit compares the real-time position against 16 user-defined cam ON/OFF angle pairs stored in non-volatile memory. When the shaft angle enters a programmed cam window, the corresponding relay output energizes, driving downstream actuators, solenoids, or PLC digital inputs. The architecture supports both absolute and incremental position references, making it adaptable to new machine builds and retrofit projects alike.

Technical FAQ
Q: Is the H8PR-16 compatible with 24 V DC PLC output modules?
A: Yes. The relay outputs are voltage-agnostic on the contact side; ensure your PLC output module can drive the relay coil voltage specified in the datasheet.
Q: Can cam angles be changed while the machine is running?
A: OMRON recommends programming cam angles with the machine at rest. Some firmware versions support online editing — consult the H8PR operation manual for your specific firmware revision.
Q: What encoder interface does the H8PR-16 accept?
A: The H8PR-16 accepts standard incremental encoder inputs. Verify pulse count per revolution compatibility with your encoder specification before installation.
Q: Do you provide OMRON certificates of conformance?
A: Yes, CoC documents are available for volume orders. Contact us at [email protected].
Q: What is the minimum order quantity?
A: No minimum order quantity. Single units are available; volume discounts apply at 5+ units.
