malamang may phototransistor or something similar for detection yan  para pag nainterrupt yung reception sa source, ititigil nya pansamantala yung machine...

Yep, linear array of IR transmitter receiver pair. Isa pair lang ang ma-block sapat na para matrigger and output. Available ito with NPN or PNP output for direct wiring with PLC inputs.

i think keyence nga yun.... malulupit din ang keyence pag dating sa mga sensor eh.... sobrang compact pero malupit ang features... meron akong isang natago dito na sensor ng keyence. yung ginagamitan ng fiber optic cable. di ko lang matandaan ang exact model nya.
