The TX-S series Signal Rely with LT style pin layout, very high sensitivity and 50mW (nominal operating). It offers nominal operating power of high sensitivity of 50mW. By using the highly efficient polar magnetic circuit "seesaw balance mechanism", a nominal operating power of 50mW (minimum operating power of 32mW) has been achieved. High contact reliability is achieved by the use of gold-clad twin crossbar contacts, low-gas formation materials, mould sealing the coil section and by controlling organic gas in the coil. The structure of the mould-sealed body block of the coil section achieves nominal operating power of 50mW and high sensitivity, along with low thermal electromotive force, reduced to approximately 0.3mV.
