The GO™ Switch Model 81 offers end sensing and an optional Double Pole Double Throw (DPDT) contact arrangement with a 1/4 sensing range. Wiring options include AC, DC, N/O, or N/C choices.
Sealed contacts, rugged housings, non-contact detection of ferrous metal & magnetic targets, and snap action response make the switches the ultimate problem solvers for troublesome mechanical limit switch applications.
