Incremental rotary encoder MRH-TD

magnetichollow-shaftnon-contact

Product overview
The MRH-TD is a dual-channel, bearingless magnetic incremental encoder supplied as a tandem set. Two fully independent MRH sensing units are joined by a precision spacer to provide true redundancy in a compact footprint. Its non-contact architecture imposes zero shaft load, tolerates misalignment, and resists shock, dust and oil — making it suitable where reliable speed and position feedback is critical and installation space is limited.

Application background
Developed to meet severe envelope constraints for an automated guided vehicle (AGV) manufacturer, the MRH-TD replaces bulky paired hollow-shaft encoders. The tandem format yields cleaner mechanics, lower weight, elimination of bearing wear and improved availability for mobile platforms that require minimal downtime. Two isolated sensing paths deliver independent outputs for verification and continuity, supporting safety-conscious system designs without increasing footprint.

Why teams choose MRH-TD

• True redundancy: dual, isolated channels for continuous operation and signal cross-check.
• Compact by design: tandem format with a slim profile to simplify integration in constrained spaces.
• Non-contact durability: zero shaft load; tolerant to misalignment, shock, dust and oil.
• Cleaner mechanics: fewer wear components, easier assembly and reduced maintenance.

Tailored to your project
MRH-TD is delivered as a bespoke build and can be configured for different ring sizes, mounting hardware, electrical interfaces and cable/connector options. It is not a standard catalog item and is supplied through Hohner’s engineering team to meet exact specifications.
