Siemens 1XP8001-1/1024 ID538725-11 Incremental Photoelectric Rotary Encoder

1. Overview of the Siemens 1XP8001-1/1024 ID538725-11

The Siemens 1XP8001-1/1024 ID538725-11 is an industrial-grade incremental rotary pulse encoder that captures angular displacement and speed in real time with a high resolution of 1024 pulses per revolution. Its aluminum housing and stainless steel shaft ensure IP66 protection and long-term operation in harsh environments ranging from –20°C to +100°C. Its 10–30 VDC wide-range power supply and HTL push-pull output make it compatible with the Siemens SINAMICS/SIMATIC series and seamlessly integrates with various third-party controllers.

Featuring a Ø12 mm solid shaft and a compact 58 mm outer diameter flange, it weighs only 0.3 kg, has a maximum mechanical speed of 9000 rpm, and boasts an axial load capacity of 40 N and a radial load capacity of 60 N, sufficient to withstand high vibration and shock conditions. A 12-pin radial connector or a 2 m (1 ft) highly flexible PUR cable is available, and plug-in wiring allows for one-step installation and maintenance. Built-in short-circuit and reverse polarity protection prevents damage to the device even in the event of field wiring errors.
