Northstar North Star Encoder HSD351024PA4

Northstar Corporation was founded by Lake Shore Cryotronics, a well-known company in the United States. Its products have won the reputation of "pioneers" in the field of industrial process control and related motion control markets. The product is at the forefront of similar products in terms of reliability, quality, technology, and service in the world. Northstar's magnetic impedance technology has changed the industry standard for encoder feedback and improved product reliability.

The NORTHSTAR brand heavy-duty encoder, medium load encoder, and digital pulse tachometer can provide high-performance speed and position feedback on large electric motors under extreme environmental conditions. These encoders also have industry standard resolution: up to 2048 PPM. Currently an important member of Danaher Industrial Control Group. Its products are widely used in heavy industries such as metallurgy, electricity, and papermaking.

HSD351024PA4 was originally named the Northstar trademark and is the star model of the Northstar heavy-duty encoder. In the early 1990s, it was widely used in industries such as steel and heavy industry. The initial model of this encoder was MH1024Z1K2S1; Subsequently, the NORTHSTAR brand under the DANAHER group updated the encoder model to HSD351024MA34/HSD351024MA340; In 1995, DANAHER Group acquired the HENGTLER brand in the United States. Shortly thereafter, the encoder model was upgraded to HSD351024PA4; In 2016, after HENGTLER was acquired by FORTIVE in the United States, the product brand was uniformly updated to HENGTLER, and the encoder model remained unchanged, still HSD351024PA4. In summary, the evolution history of this encoder model can be summarized as: MH1024Z1K2S1- HSD351024MA34- HSD351024PA4. The biggest feature of HSD351024PA4 is the use of magnetic resistance technology, which achieves higher stability. The magnetic encoder overcomes the shortcomings of traditional photoelectric encoders in principle, ensuring reliable operation in heavy-duty situations. If optical principles are used, then the encoder must also be made of materials that will not break, usually metal or polyester film materials. In order to match the application of high-power motors structurally, heavy-duty encoders generally adopt a large aperture design and can be directly installed on the end faces of various motors. In terms of shaft protection, thermal isolation and electrical isolation are generally provided.
