Metal detection reed sensor products are a great alternative to inductive proximity sensors. Available in screw fastened flange mount and PCB through-hole (THT) designs, these ferromagnetic metal detection sensors are suitable for a wide range of applications including but not limited to: end travel sensing limit switches, position control, and security uses such as door and window control, opening recognition contact and metal fire protection doors. Choose from normally open (SPST-N.O.) or normally closed (SPST-N.C.) contact forms.
