Product Description:

The HA5250050004129 Encoder is a heavy-duty incremental encoder in the H25 line, manufactured by Danaher. The encoder is made for precise motion control tasks in industrial robotics, where correct feedback is very important. The encoder has a solid shaft and a square flange fitting design, which means it can be used with a lot of common mechanical setups.

The HA5250050004129 encoder is a type E device that sends out incremental output data. It has a resolution of 500 PPR, which makes sure that the signal output for position and speed feedback is accurate. The type of shaft is solid and has a 3/8-inch width. The reader has a type B electrical output that works with TTL. The connector is a circular 10-pin MS type with a back axial orientation. The housing is constructed out of either aluminum or stainless steel, both of which are sturdy metals that contribute to the mechanical safety of the encoder. The termination style is electrical type E, and it works with MS-style connections for common interfaces. There are four mounting holes on type H mounting flanges, which have a 2.5-inch square shape and are used for a stable connection.

The encoder can work in temperatures ranging from -40°C to +100°C and can be stored in temperatures ranging from -55°C to +125°C. It can handle shocks of up to 50 g for 11 ms, which means it works well even when the mechanical load changes. The HA5250050004129 encoder is designed and built in a way that makes it work well in complex mechanical systems. All parameters were maintained to ensure reliable signal generation and structural compatibility. The HA525 encoder performs admirably in terms of motion control.
