2.1 Read Range
Read range is measured in a clean RF and electrical environment using a Pyramid Series
Standard Light Proximity Card (PSC-1) presented parallel to the reader surface with the
reader operating at 12 VDC. Like all manufacturers of Proximity Readers, Pyramid
Associates recommends a good quality, regulated, linear power supply be used with all
proximity readers.
Due to the physical size difference between the coils of various credentials, Multi
Technology Proximity Cards (PSM-2) and Proximity Key Ring Tags (PSK-3) provide less
read range than Standard Light Proximity cards (approximately 75% less and 50% less
respectively). Read range will be reduced if a reader is located in electrical or RF noisy
environments such as mounted near a computer monitor, powered by a switching power
supply, or a lack of a good earth ground. Operation at 5 VDC also might reduce read
range.
