Product Profile: Posital IO-Link Rotary Encoder

February 18, 2022
Product name: POSITAL Rotary Encoder with IO-Link Communications Interface
What is it? IO-Link is a low-cost, easy-to-implement communications system designed to simplify connections between large-scale fieldbus or industrial Ethernet networks and sensor or actuator devices located on the factory floor. On one side of an IO-Link master gateway device is an interface to the plant-wide network, while the other side has multiple point-to-point connections to individual sensor devices. The IO-Link interface for end devices is relatively simple, eliminating the need to support complex communications protocols at the sensor/actuator level. IO-Link supports a variety of data types, including measurement data, device configuration instructions and information about operating condition parameters such as temperature.
Multi-turn models include new features, including: 16-bit resolution, the ability to output rotation speed directly to the controller and the addition of electronic cam/preset/reset functionality (making use of binary digital signals transmitted through Pin 2 of the connector), and extended device diagnostics. Temperature and vibration sensors built into multi-turn encoders enable monitoring condition parameters. Rotation counters on multi-turn models are powered by energy harvested from the rotation of the device’s shaft, ensuring that the rotation count is always up to date – even when movements occur when power is unavailable. This eliminates the need for backup batteries and helps to reduce maintenance costs.
Key features:
- Magnetic Multiturn Sensing without Gear or Battery
- Condition Monitoring via Temperature Sensor and Vibration (coming soon)
- Hardware I/O-Pin for Preset, Reset or Cam Switch
- Simple Wiring Reducing Costs
- Automatic Parameterization after Device Replacement
