Model 1000 Series (Extreme)
The Model 1000 Series is designed to meet the extreme robustness demands of the steel industry. With its sturdy bearings the product has an exceptional durability in all applications of high mechanical loads, vibrations and shock. The encoder has a high encapsulation level, IP67, to protect its inner parts from dust and liquids of a harsh environment. As a special option, the housing can be provided in stainless steel. Several incremental and absolute versions are available, and a combination of the two encoder types can be integrated in the same product. The absolute variants are available with interface for SSI, EnDat, PROFIBUS, DeviceNet™, CANopen and with parallel output.

The photoelectric rotary encoder is used to establish an informational link between the key components of machines, industrial robots, comparators and DCC, NC or Digital Readout units. It gives information about the value and direction of the motion components. The encoder is used in automatic control, on-line gauging, in process monitoring systems, etc.
The encoder consists of three parts: mechanical, optical and electronic.
The case of the encoder is fixed to an object by means of screws. The shaft of the encoder is connected with an object shaft by virtue of a compensating coupling.

Rotary Optical Encoder is a sensor that converts machinery positional information into corresponding pulse numbers or digital data by photoelectric signals. Therefore, it can detect the speed, position, angular velocity, distance and counts information relating to mechanical machine. It is usually applied on the angle-measuring device and equipment. Hence, it is a very important device in industrial automation field.
Delta ROE series provides precise positioning and speed sensor function. Major applications include main hoist of crane (crane control), CNC tooling machine, elevator, conveyer, textile machine, and storage equipment, etc. industry related machine. Also, it can also be built inside of many kinds of servo motors, brushless DC motor (BLDC) and induction servo motors, and converts rotary motion or position to electronic pulse numbers for phase change, speed and position detection.
