safety issue with sensor?

Hi,

I have a sensor that I have on a tiny breadboard 4 x 4. Its an IR, passes 100ma, works great. I want to mount it with 2 sided sticky tape on metallic-like frame. Its connected with Arduino cable a couple of feet from the base breadboard. Then it hit me, the bottom of the tiny breadboard seems somewhat exposed - do I need a layer of insulation tape (2 sided sticky) that insulates or maybe I need to put it in a enclosure? Ideally would like to leave it as is and mount it, but am concerned about bottom of sensor mock-up and 100ma.

With the voltages present on the PCB, there is no safety hazard with regards you touching any part of the circuit – hence an enclosure protecting against accidental contact (for safety purposes) is not required.

However it is entirely possible that some conductive object/surface may contact the PCB, causing the circuit to malfunction and/or component damage – therefore some form of protection should be considered. An enclosure may be more aesthetically pleasing versus a layer of PVC insulation tape.

This photo seems to indicate that the breadboard is backed with 2 sided sticky material. This is reassuring that my intentions are pretty much the same with the small breadboard:
