Since 2001, Shanghai Hengxiang Optical Electronics Co., Ltd. has been developing high-precision rotary encoders for industrial automation. Among our portfolio, the absolute encoder series stands out for applications where position data must be retained even after a power loss.
ZM35 Series – The Latest Innovation
Our newest addition, the ZM35 multi-turn absolute bearing-less encoder, is engineered for space-constrained applications. With an outer diameter of just 35mm and a thickness of 11.8mm, it weighs approximately 80g. It delivers ±80″ accuracy and single-turn resolution of 24 Bits, expandable to 32 Bits, with up to 24 Bits of multi-turn data retention. The non-contact photoelectric reflection principle ensures durability, while BiSS_C/SSI interface support makes it ideal for servo motors and robotics.
Comprehensive Product Line
For larger applications, the PM82 series offers an 82mm diameter with a thickness of just 12.5mm, providing up to 24 Bits resolution and ±80″ accuracy. The KM60 series features a robust 60mm housing with IP65 protection and -40°C to +95°C operating range. The SJ50-T and SJ58-T series deliver up to 12-bit (4096 PPR) resolution, with wide voltage support (DC5V & DC8-30V) and IP65 protection. For servo motor feedback, the KN40-J series achieves resolution up to 40,000 P/R.
From miniature 22mm designs to heavy-duty 82mm models, Hengxiang absolute encoders are trusted across CNC, robotics, elevators, medical equipment, and beyond.
