Hi George. My sensors look nothing like those. Mine are @ 1x1x5/8" black with a poured in black tar type silicon. Has a square label on one side (the 'tar' silicon poured in side), a barcode with numbers label on the other side and end (away from the stem). If you cut the ones in the picture in half right below the stem, that's about the area of the ones that came out of mine. Very different from the picture in all aspects.
