Yeah, that's definitely NOT the early 90-93 VH45DE sensor. It looks similar though. I have a spare early VH45 here now because I switched to a later style '94 motor.
There is a stamping on mine along the outer metal case. It's very faint though. The marking says 23731 60U13. The last few numbers are stamped with a different "font", probably because they are stamped later with a different machine due to the fact that they often have minor variations in parts to increase reliability, decrease costs, change materials so they are more resistant, etc... This is the mitsubishi version of the part, and I think the other is hitachi.
My specific number corresponds to a 1991 Infiniti Q45. Check your housing very carefully and try to find a part number stamping, however faint. Whatever it is, it will almost certainly begin with 23731 since that seems to be Nissan's part number prefix for camshaft sensor.
