In the context of the Superconducting Proton Linac (SPL) studies at CERN, a wire position sensor is developed. This sensor is designed in order to be tested for its eligibility in the alignment concept based on a stretched wire system. Development and test of the optical wire position monitor capable of working at low temperatures and under vacuum, it has been shown in this work. The test sensor contains three phototransistor type SHARP GP1S56TJ000F. GP1S56TJ000F is a standard, phototransistor output, transmissive photointerrupter with opposing emitter and detector in a case, providing non-contact sensing. For this family of devices, the emitter and detector are inserted in a case, resulting in a through-hole design. This device is unique because it uses position pins to insure accurate placement on the PCB, and has the short profile. The measuring system it was made using MX840A is the 8-channel universal amplifier of HBM's QuantumX data acquisition system and supplemented by the control electronics of his own design. The tests were performed under laboratory conditions at cryogenic conditions (77[K]), the results were presented and discussed.
