be 80 ms or more to ensure that the OSSD maintains the OFF state for more than 80 ms.
*3 “All blocked” means the situation where the GL-R operates in optical synchronisation system and the
transmitter and receiver is not synchronised (top and bottom beam axes are both blocked). In this situation,
the response time is longer because the GL-R synchronises the transmitter and receiver fi rst and then

*2 If the interruption is present in the detection zone for less than 80 ms, the response time (OFF to ON) will
be 80 ms or more to ensure that the OSSD maintains the OFF state for more than 80 ms.
*3 “All blocked” means the situation where the GL-R operates in optical synchronisation system and the
transmitter and receiver is not synchronised (top and bottom beam axes are both blocked). In this situation,
the response time is longer because the GL-R synchronises the transmitter and receiver fi rst and then
determines the clear or blocked.
*4 When the GL-R is used under surrounding air temperatures between 50 to 55°C, the Maximum load current should not exceed 350 mA.
