MOC-7811 IR Opto-Isolated Slot Sensor MTBF, Sensitivity of signal due to bending

[kfc_n]

Good day,

   I need help on these details regarding MOC-7811 IR OPTO ISOLATED SLOT SENSOR:

  1.) MTBF in terms of hours used?
  2.) Sensitivity of sensor when it comes to bending of receiver and transmitter pole, tolerance in distance? thanks
  3.) Does anyone here has a copy of product catalog of MOC-7811 IR Opto Isolated Slot Sensor?

Thanks and more power!
