Hall effect devices produce a very low signal level and thus require amplification. The vacuum tube amplifier technology available in the first half of the 20th century was too large, expensive, and power-consuming for everyday Hall effect sensor applications, which were limited to laboratory instruments.

Next Generation Load Device-Medium (NGLD-M) - replacement for the Simple Key Loader. [1] AN/PYQ-10 Simple Key Loader (SKL) - originated in 2006 as a replacement for the DTD. KIK-30, a more recent fill device, is trademarked as the "Really Simple Key Loader" (RASKL) with "single button key-squirt." It supports a wide variety of devices and keys. [2]
The planar Hall sensor is a type of magnetic sensor based on the planar Hall effect of ferromagnetic materials. [1] [2] It measures the change in anisotropic magnetoresistance caused by an external magnetic field in the Hall geometry. As opposed to an ordinary Hall sensor, which measures field components perpendicular to the sensor plane, the ...
In ferromagnetic materials (and paramagnetic materials in a magnetic field), the Hall resistivity includes an additional contribution, known as the anomalous Hall effect (or the extraordinary Hall effect), which depends directly on the magnetization of the material, and is often much larger than the ordinary Hall effect.

This part dates back to the joint valve code key (German: Röhren-Gemeinschafts schlüssel) negotiated between Philips and Telefunken in 1933–34. Like the North American system the first symbol describes the heater voltage, in this case, a Roman letter rather than a number.
1×6 pin header (one row) 1×6 female header (one row) A pin header (or simply, header) is a form of electrical connector.A male pin header consists of one or more rows of metal pins molded into a plastic base, often 2.54 mm (0.1 in) apart, though available in many spacings. [1]
