Rotary Limit Switch - Stromag Planetary Gears Series 51 - 29:1 ratio 6 pole

Description

These are very high quality, extremely dependable endless rotary limit switches; German engineering at it's finest. We have been using these in critical systems that travel around the world for over a quarter century and have NEVER had one fail. They are very easy to adjust and the adjustments never wander or drift. Their patented planetary gearing features absolutely no backlash. This unit has a gear ratio of 29 to 1 and has six rotary cam driven double throw poles, each independent of the others and infinitely adjustable. The 5/16" diameter x 7/8" long shaft has a keyway for a #213 Woodruff key (1/8" wide) which is included. Please note that the disconnect tab on the common connector for each pole has tarnished for some unknown reason. It does not have any effect on the quality of the connection (no increased resistance, etc). These have always been kept in a controlled environment. These are part of a massive inventory reduction and consolidation which is how they became available at such a low price. Please contact me if you have any questions, I have other ratios and pole counts available - see my other auctions.
