Through-Beam Sensors

Through-​beam sen­sors de­tect and count small parts, de­tect the edges of ob­jects and mo­ni­tor pas­sages in sys­tems. The emit­ter and re­cei­ver are hou­sed in se­pa­rate hou­sings ac­cor­ding to the through-​beam mode. The sen­sor switches as soon as an ob­ject in­ter­rupts the laser light, red light or in­fra­red light.
