The HS40 absolute rotary magnetic encoder with hollow shaft offers unparalleled durability, designed to withstand extreme conditions such as temperature cycling and liquid sprays. With massive bearings and the industry’s best shaft sealing system, the HS40 guarantees reliable performance in even the harshest environments.

The magnetic sensor can easily detect through oil, dust, and dirt, making it more reliable than ordinary optical encoders, which are often disabled by such contaminants. This makes the HS40 perfect for heavy-duty industrial applications that demand precision and longevity.

Additionally, the HS40 does not rely on batteries, capacitors, glass disks, or gears, as it uses Wiegand wire energy harvesting technology combined with magnetic sensors, ensuring long-lasting performance without the need for frequent maintenance.

The encoder is designed to fit full-size shafts, easily accommodating both NEMA and IEC frame motors without requiring special modifications.

It also features shaft current isolation and interchangeable bore sizing inserts for easy customization. Offering a wide range of communication protocols, including analog outputs, CANbus, DeviceNet, J1939, and SSI, the HS40 provides versatile integration for various positioning applications. Choose the HS40 for the most reliable and durable hollow shaft encoder for your critical systems.
