A five volt excitation is needed to supply power to the device. The operating temperature range for the NPI-12 Series is 50F to 104F (10C to 40C), while the storage temperature is -40F to 158F (40C to 70C). Electrical connection is accomplished with a 4 pin connector that accepts standard 0.025 in (0.64 mm) square posts on 0.100 in (2.54 mm) centers. A red wire allows for easy recognition of connector orientation. NPI-12 Series schematic diagram NPI-12 Series dimensions
