Product Description:
Beckhoff's EL5021 is a small and multipurpose EtherCAT terminal that is intended for industrial automation applications that need accurate position measurement. With a weight of just around 55 grams, this terminal is very light and ideal for installations with limited space. For precise signal transmission, it efficiently reduces noise and interference by connecting to a single encoder with a differential input of 1 Vpp. The differential input improves signal integrity and system dependability by canceling common-mode noise by using two signal lines with opposing polarity. Because of its 24-bit maximum counter capacity, this terminal can monitor a large number of locations with excellent resolution.
High-speed encoder signals may be precisely captured and processed by the EL5021 because of its remarkable 250 kHz input frequency capability and 10-bit resolution. This feature ensures the system can keep up with dynamic changes in the encoder output, which is essential for applications requiring accurate positioning and quick motions. A number of special features that improve the EL5021's usefulness and adaptability are included. These include a reset function to reset the counter, a latch function to record and store particular encoder data, and the ability to alter the counting orientation, which enables flexible integration with various encoder types and motion control situations. The frequency-dependent period resolution optimizes performance across a range of operating situations by automatically modifying the measurement resolution according to the input frequency.
The purpose of the EL5021 is to endure the demanding conditions of industrial settings. It is protected against solid items bigger than 12mm, such as fingers or tools, thanks to its IP20 protection grade, which also helps to avoid unintentional contact with internal components. The terminal ensures constant performance even in difficult environmental circumstances by operating dependably in the temperature range of 0 to +55°C and being able to be kept at temperatures ranging from -25 to +85€. It is also appropriate for applications that are susceptible to mechanical stress since the EL5021 conforms with EN 60068-2-6 and EN 60068-2-27 requirements for shock resistance and vibration resistance, respectively. It also satisfies the strict electromagnetic compatibility criteria of EN 61000-6-2 and EN 61000-6-4, guaranteeing that its functioning won't interact with other devices or be impacted by outside electromagnetic disturbances. The EL5021 comes with a one-year guarantee from Wake Industrial, giving buyers confidence in its dependability and quality.
