OPTEK - pn: OPB804 is a replacement optical interrupter used on many William/Bally pinball machines. It's like a Swiss Army Knife of optics. It has a higher output current of 30ma. It replaces 20ma output Williams PN: 5490-12451-00 (QVE11233 short leg version) and Williams PN: 5490-13451-00 (QVE11233.0086 long leg version). Also replaces the QVA11233 short version. The legs on the OBP804 we have are bit longer than the QVE11233.0086 long version used on the Twilight Zone Minute Opto PCB assembly.
