It provides two normally-closed (NC) contacts with positive opening — the mechanical action that forces the contacts apart even if they weld, a requirement for safety circuits in machine guarding applications. ## Integration & Wiring The switch uses screw fixing for panel or machine mounting, and the electrical connection is via AS-i insulation displacement — no separate terminal block needed for the bus drop. The separate actuator (ordered separately) allows alignment flexibility on guard doors or sliding gates.","metaTitle":"Siemens 3SF3243-0XX30-0BA1 Communication-Capable Position Sw","metaDescription":"Siemens 3SF3243-0XX30-0BA1 communication-capable position switch with AS-i adapter, IP65, positive opening, 2 NC contacts.
