The plug can be obtained under the designation Q.bloxxTerminal B14/120-A106 with120 or B14/350-A106 with 350 from Gantner Instruments Test & Measurement GmbH.The bridge excitation voltage can be 2.5 V or 5 V (DC or CF).IMPORTANTThe plug must have the same resistance values as the straingauges used, because otherwise no measurement is possible.Fig. 4-43 A106, measurement with strain-gauge quarter bridgeusing Q.bloxx Terminal B14.4.12.3 Inductive full and half bridgesWith inductive full bridges all connections are occupied. If thesensor has no sensing leads, you specify this during the moduleconfiguration (Type column). With half bridges the side drawn indashes and the connection 10 are omitted.The bridge excitation voltage can be 2.5 V or 5 V.9(10)5 (+)786 (–)120 Ω 350 Ω679679
