Pagination or Media Count:
A magnetic amplifier housing uses a base, dowel and shunt to magnetizable material to concrete the magnetic field of a ring magnet through a HAll Effect transistor to provide an improved detector device with increased gain. The detector device cause polarity reversal when tampered with, ensures positive mechanical alignment of the transistor and mechanical components, and protection of the transistor from mechanical damage.
