OPB815L datasheet



The OPB815L consists of an infrared Light Emitting Diode (LED) and an NPN silicon phototransistor mounted in a low-cost plastic housing. The device is designed to switch electrical states when an opaque object is passed through the slot.

The slot is wider and deeper than many slotted switches and will accommodate a variety of different materials. This device can be ordered with PCBoard solderable leads (OPB815L) or with 26 AWG stranded, UL rated wire length of 24” [610 mm] (OPB815WZ).


1. Wide slot width: 0.375” (9.5 mm)

2. Deep slot depth: 0.430” (10.9 mm)

3. Selectable wire lengths from 6” (152mm) to 24” (610 mm)

4. Seven popular connector options



1. Non-contact object sensing

2. Assembly line automation

3. Machine automation

4. Equipment security

5. Machine safety
