External laser switching
Series LLT27xx(502), LLT27xx(503), LLT27xx(504) and LLT27xx(505) sensors offer this
function.
i
Sensors of Laser Class 3B (IIIB) need an external key switch to switch off the
laser.
Use a serial key switch inside the control circuit to switch off the laser. You will
find details for the wiring in the instruction manual, Chap. 5.2.4.

The RS422 port can be used with either of the following configurations:
- RS422: Loading of programs and transmitting of measurement results.
- Synchronization/Triggering: Synchronization resp. triggering using switching
signals.
1) Optional RS422 interface cable (SC2700-4,5RS422) from Micro-Epsilon, compati-
ble to the RS422 to USB converter. All outputs or inputs are designed symmetrically.
Internal terminating resistors 120 Ohm.
