Zeeman measurement is the only tool to probe the magnetic field strengths directly. A new receiver covering 30-50 GHz frequency range is proposed for Nobeyama 45-m telescope based on the design of the ALMA Band 1 receiver. With dual linear polarization feed, wide IF bandwidth and state-of-the-art noise performance, it is capable to observe three Zeeman transitions (SO at 30.0 GHz and CCS at 33.7 and 45.4 GHz) toward the pre-protostellar cores simultaneously. This feature will not only increase the survey efficiency but also provide a reliable tool to calibrate the unwanted instrumental cross-polarization. Slim receiver layout also allows easy expansion to form focal plane array. We will present the receiver design and the current status of the pro
