Product Description:
The E4809-024-019-A Type E Absolute Encoder by Okuma is a precision device designed to provide reliable position feedback in CNC machinery and industrial automation systems. As a relative encoder, it still holds shaft position information even in the event of a power loss. It negates the homing procedures and provides an accurate restart operation.
The E4809-024-019-A Type E Absolute Encoder has an optical sensing technology, coupled with an integrated circuitry. This allows it to be accurately measured and eliminates signal drift, and is therefore highly effective in machine tool applications. The encoder runs on a 5V DC power supply with a constant current. This provides consistent control system outputs. It provides absolute position data with high resolution to ensure that every axis location is measured precisely. The E4809-024-019-A Type E Absolute Encoder has multi-core shielded wiring and a solder PCB interface. This can reduce electrical noise and ensure that there is good communication between the encoder and the CNC control system. It has vibration resistance of 10-55 Hz with 1.5 mm amplitude. The shock resistance of the unit is also rated at 98 m/s2 (10G) to withstand severe operational stresses. The encoder can also work reliably even up to 1000 meters high. It has an environmental tolerance of 20-85% operating humidity (non-condensing) and 90% storage humidity.
