The ProLine Takt Timer is an affordable way to visually see if your products are being produced in time to satisfy the customer demand.  The photo-sensor will start the timer after the first product leaves the sensor.  The ProLine Takt Timer can be set to time up or down and will display the time on the screen.  If production is running on time or ahead of schedule, the timer automatically resets after each product passes the sensor.  If production is underperforming, the output is asserted until the next product passes the sensor, then both the time and the output will reset.
