The SICK WE150-P430 is a highly robust, industrial-grade absolute multiturn encoder from SICK's extensive portfolio. It is designed to provide precise and reliable angular position data in the most demanding automation and drive technology applications.
Key Features & Technical Specifications:
Function: Absolute Multiturn Encoder. It provides a unique digital code for every single position of the shaft, both within one revolution (singleturn) and across multiple revolutions (multiturn). It maintains this position data without the need for a backup battery, even after a power failure.
Interface/Protocol: The -P in the model code signifies the Push-Pull (HTL) / Quadrature output signal. This is a common industrial interface that provides both an analog incremental signal (A, /A, B, /B) and a digital index signal (I, /I), often compatible with standard frequency inverter inputs.
Resolution (Singleturn): The number 430 indicates the singleturn resolution. This typically corresponds to a 13-bit resolution, providing 8,192 (2¹³) distinct positions per single revolution of the shaft.
Number of Turns (Multiturn): The 150 in WE150 specifies the number of full revolutions (turns) the encoder can mechanically count and store. This model can absolutely track and remember its position across 150 full revolutions.
Safety Option: Many variants in the WE series can be equipped with Functional Safety capabilities (e.g., according to SIL 2/PL d). If this is a safety encoder, it would have a designation like WE150S-P430.
Design & Build: It features an extremely robust metal housing (often stainless steel) and high protection ratings (typically IP65, IP66, or IP67), making it resistant to shock, vibration, oil, coolants, and other harsh environmental conditions found in industrial settings.
Mounting: Designed with a synchron or servo flange (e.g., according to IEC DIN 60 952), allowing for easy and direct mounting onto motors and machinery.
Power Supply: Operates on a standard industrial DC voltage range, commonly 10...30 VDC.
Summary of the WE150-P430:
In essence, the WE150-P430 is a battery-free, 150-turn absolute encoder with a 13-bit singleturn resolution and a Push-Pull (HTL) incremental output.
Typical Applications:
This encoder is built for heavy-duty applications where reliability is paramount:
Mobile Machinery (e.g., boom positioning, steering angle)
Crane and Hoisting Systems (for precise load positioning)
Packaging Machinery
Material Handling Systems
Drives and Motor Feedback systems requiring robust absolute feedback without batteries.
