The package also features mounting tabs for fixing down with screws. With a 3 mm gap, the H21Ax requires an object from opaque to IR to interrupt the connection between the IR LED and sensor.
Suitable applications for the H21Ax slotted interrupters include printers and optoelectronic switches.

Features of the H21Ax slotted interrupters:
IR LED and NPN phototransistor
Single channel
High gain
Opaque polycarbonate package
