IR Detector
Use C2 (not yet installed, 2200 pF film capacitor marked 2n2K63) as a guide to forming
the bend in the leads as shown in Figure 26. This places the center of the bent leads about
0.1” from the edge of the IR detector body.
Figure 26-Bending the IR Detector Leads and setting the mounting height
Insert the IR detector on the same side as the switches, and solder the three leads on the
other side of the controller PCB. You can set the height perfectly by temporarily placing
C2 underneath the IR detector. The spacing isn’t critical, but if you set it too high off the
board, it will bump into the IR window in the front panel. The top surface of the IR
detector should be about 0.3” off the PCB.

Earlier versions of the PR-101 used P/N TSOP39238. That part came in a holder that was removed and
discarded.
