Redundant encoders in 58mm housing

Redundant encoders in 58mm housing

Product catalog summary

Overview: The document discusses the features and benefits of Wachendorff Automation's robust redundancy industrial encoders, which integrate optical and magnetic sensor technology within a 58 mm housing. These encoders are designed to enhance machine security through redundancy and diversity in measuring principles.

Specifications: The encoders feature a protection class of IP67, with the shaft rated at IP65. They can handle high bearing loads of up to 220 N radial and 120 N axial. The encoders offer two full-fledged systems in one housing, utilizing both optical and magnetic measuring principles to achieve high performance levels when combined with safe controllers or speed monitors.

Reliability and Diversity: Wachendorff Automation emphasizes reliability through the use of diverse sensor systems that have been developed in-house over many years. The encoders are designed to react differently to disturbances, ensuring that they do not fail simultaneously, thus allowing connected electronics to detect potential failures reliably.

Performance and Cost Efficiency: The encoders support safety functions in line with Performance Level d or SIL 3 standards. They provide redundant signals that are independently generated but can be correlated, allowing the use of standard components to achieve required safety levels cost-effectively.

MTTFd and Safety Planning: The document highlights the importance of considering the MTTFd value in safety planning. The encoders have an MTTFd value rated as "high," enabling the achievement of Performance Level D (PLd) even with low diagnostic coverage. The document advises on ensuring positive locking of mechanical connections to prevent slippage.

Product Variants: The document lists available encoder models, including WDGR 58B and WDGE 58B, which offer incremental magnetic and optical options with varying signal shapes and resolutions.
