^1 The maximum operating speed of the detected object is 2.0 m 6.6'/s. ^2 When the optional front protection cover is attached to either the transmitter or receiver, the detecting distance is shortened by 0.5 m 1.6'. When attached to both, it is shortened by 1 m 3.3'. ^3 If light blocking time is 80 ms or less, the response time (OFF>ON) will be slowed down to a minimum of 80 ms to ensure that the OSSD remains OFF for 80 ms or more. ^4 “All blocked > ON” is the time it takes for the transmitter and receiver to turn ON from an unsynchronized state (both upper and lower end beam axes are blocked). Since the reception or blockage of light is determined after the transmitter and receiver are synchronized, the response time is long. ^5 The current of control output (OSSD) is not included. ^6 When the ambient operating temperature is between 50 and 55°C 122°F and 131°F, set the indicator mode to Light OFF mode.
