We developed a custom solution for the AMG11S25H1024 encoder, intended for hazardous-area rotary feedback systems where multiturn absolute position tracking must operate together with 1024-pulse HTL incremental feedback. This configuration combines SSI absolute data transmission with HTL pulse output in a solid shaft Ø11 mm structure, giving the system better noise tolerance than TTL while keeping pulse load lower than 2048-pulse versions. It is not a high-speed margin design. It is a controlled dual-output configuration where signal quality and interface matching determine reliability.
Typical production lead time: 15 working days.

Signal usability at this interface level depends directly on the structure, cable routing, and installation quality shown here.
System Limits
This configuration is limited by SSI timing stability and HTL signal integrity, not by mechanical capability.
The absolute channel depends on stable SSI clock and data synchronization. The incremental channel uses 1024-pulse HTL output, which provides better noise tolerance than TTL and lower signal burden than 2048-pulse versions, but it still requires controlled installation quality. The system does not fail because of shaft load or rotation speed. It fails when SSI communication loses synchronization or when incremental pulse edges become unreliable under real cabinet conditions. The SSI clock range is 100…800 kHz, and the mechanical speed limit is 3500 rpm, so this version must be treated as a signal-controlled configuration rather than a mechanically limited one.
Priority of limits:
- Signal quality becomes unstable before mechanical limits are reached
- SSI synchronization and HTL edge integrity determine whether the system remains usable
This configuration is limited entirely by signal handling capability and installation quality, not by encoder structure.
Installation and Wiring Constraints
Electrical installation determines whether this encoder can remain usable.
- SSI requires stable clock and data timing
- HTL output still requires clean routing and correct input matching
- Poor shielding, grounding errors, or parallel routing with motor power lines will damage both absolute and incremental signal quality
Field boundary:
- Long cable without proper shielding control → controller cannot interpret position data reliably
- High-noise cabinet environment → incremental feedback becomes unstable before mechanical limits are reached
- Incorrect HTL input matching → pulse output cannot be used correctly
The mechanical platform is robust, with IP67 protection, Ø11 mm solid shaft, and admitted shaft load up to 250 N axial / 350 N radial, but signal-side mistakes will still cause failure first.
Replacement and Interface Mapping
- Only valid when the system supports SSI absolute input and HTL incremental input together
- Suitable for applications requiring multiturn absolute tracking with better noise tolerance on the incremental side
- Not applicable when cabinet EMC control or signal matching cannot be maintained
- Connection form and interface details can be adjusted within the custom solution scope
Delivery and Customization Scope
This solution can be customized in connection type, output matching, and mechanical interface details according to the target control system. Typical production lead time: 15 working days.
