Medium-duty absolute encoders, suitable for applications with moderate shaft loading and flexible shaft couplings, are used where position data must be retained through power cycles. Koyo TRD-NA series IP65-rated absolute encoders with 8mm solid shafts have open-collector (sinking) gray code output, and are available with up to 11-bit resolution (2048 PPR).
Why use an absolute encoder? When power is cycled using an incremental encoder, any positioning information is lost until home position is triggered. An absolute encoder uses gray code (a version of binary where the physical inputs only change state one bit at a time) to describe each position, so position data is not lost when power is cycled. Absolute encoders are wired to standard PLC DC input cards and do not require a high-speed input module.
Encoders are used in all types of motion sensing applications, including machine tooling, semiconductor positioning and multi-axis positioning. All Koyo encoders feature a reinforced aluminum diecast casing and come equipped with a two-meter cable or MS connector. Use the absolute encoders with standard DC PLC inputs. The Totem Pole output of the absolute encoders can work with sinking or sourcing DC PLC inputs cards (not high-speed inputs). The lowest resolution absolute encoder has 5 signal outputs and a resolution of 32 positions per encoder revolution. The highest resolution absolute encoder has 11 signal outputs and a resolution of 2048 positions per encoder revolution. Mounting brackets and flexible couplings in aluminum and glass reinforced resin are also available.
