Abstract
"SENSOR DE POSIçãO MAGNéTICO PASSIVO". A presente invenção refere-se a um sensor de posição passivo magnético, compreendendo um substrato (1) com uma rede de resistência (2) que fica disposta sobre este substrato (1) e é atribuída a uma estrutura de mola de contato (8), que pode ser defletida sob a ação de um ímã permanente (11), com uma conexão elétrica entre a rede de resistência (2) e a estrutura de mola de contato (8) sendo estabelecida por meio do contato que é dependente da posição do ímã permanente (11), a estrutura de mola de contato (8) e a estrutura de resistência (2) sendo encerradas em um alojamento selado (1, 12), e o ímã permanente (11) sendo móvel para fora do alojamento selado (1, 12). No caso de um sensor de posição com uma força magnética maior do ímã permanente (11), o ímã permanente (11) fica polarizado na direção de movimento da estrutura de mola de contato (8), um dispositivo de orientação de fluxo (14; 15a, 15b) para aumentar a concentração da força de atração do campo magnético não perturbado sendo disposto próximo ao ímã permanente (11).
