Redundant Encoder Options

In the world of rotary encoders, modern non-contact sensing technologies and high MTBF (Mean Time Between Failures) specifications are standard. However, in critical applications, redundant sensors are still a necessity. When selecting a solution, several criteria need to be considered, and fortunately, various options are available to simplify the task. Understanding Redundancy in Encoders The […]

How To: Use an Open Collector Output

All new Gill level sensors come with a secondary output function which operates as a high or low level switch. So what is it and how do I use an Open Collector switch output?

Inductosyn: End of an Era, New Opportunities or Both?

Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.

Safety First – Selecting the Right Position Sensors for Safety-Related Motion Control

POSITAL has introduced an inexpensive and flexible alternative for safety-critical motion control systems. When combined with functional safety PLCs, these devices are suitable for applications that are required to conform to Performance Level/ PL d, Cat. 3, according to ISO 13849.
