As an absolute encoder, it provides a defined position on power-up, supporting reliable startup sequencing and closed-loop control in equipment such as conveyors, packaging lines, robotics, and machine tools. The 845A series is built to withstand rugged industrial environments and integrates with Rockwell Automation hardware and software ecosystems, making it a common choice for OEMs and maintenance teams seeking durable, long-life position feedback. The model designation 845A-SJZ1FN1AK3 identifies a specific configuration within the series suitable for single-turn absolute measurement, enabling straightforward interpretation of shaft angle by controllers and drives that expect an absolute code per revolution. This encoder is typically used where predictable, repeatable positional data is required for motor control, indexing, and synchronization tasks, helping to reduce errors during startup and in continuous operation across a range of manufacturing and material-handling applications. In practice, users mount and interface it following Allen-Bradley guidelines for 845A encoders, ensuring reliable performance in environments such as automated packaging lines, material handling, and robotic assembly.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46245620547818,"sku":null,"price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-081.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-845a-sjz1fn1ak3-optical-absolute-encoder","provider":"GTG Hardware","version":"1.0","type":"link"}
