Abstract
A delay circuit 2 utilizes two comparator timers 4 and 6 and a minimum of logic to achieve a combination ON/OFF delayed function. The comparator timers 4 and 6 are resettable independently of each other such that each respective ON or OFF delay function may begin retiming without waiting for the other delay function to time out if the input signal transitions back and forth before the end of the respective ON or OFF delay. The delayed circuit 2 is ideal for proximity switch applications, particularly photoelectric type proximity switches, for providing a delayed output signal following a given sensed condition.
