How many times can you open and closed a quarter turn solution from the 50F 900N series when using the receptacle V50R4-2-1AK7?

Question We are looking to use a quarter turn solution from the 50F 900N series. The parts we selected are 50E8-9W0AGV, 4002-SW-SS and V50R4-2-1AK7. We are wondering how many times this setup can be used before it will fail. Also where would it fail? Answer Thank you for asking your question. No real tests have been done on this matter, however base on previous experiences we are able to give you an estimated answer. When repeatably opening and closing this setup, and any similar setup with the receptacle V50R4-2-1AK7, these are the results: 250 times repeatability ensured 500 times repeatability might be possible depending the environmental influences 1000 times repeatability is not possible. As to the second part of your question, The weakest element of any quarter turn solution, is the part that supplies the spring force to make your quarter turn operational. In the 50F 900N series the spring force is applied by the receptacles. This implies, in your case, that when you need to replace parts, it will be the receptacle V50R4-2-1AK7.
