Description
xThe NZ1HS-538-M is a mechanical safety position switch with a lever arm actuator fitted with a steel roller, used to detect the position of guards, doors or covers on industrial machinery. It uses positively driven contacts with a slow-action switching principle, giving two door position contacts rated for DC-13 4 A 24 V and AC-15 4 A 230 V duty. The die-cast alloy housing with silver alloy, gold-flashed contacts is rated IP67 and suited to ambient temperatures from -25 to +80 °C, making it applicable in demanding industrial environments where reliable guard monitoring is required. Connection is via a single M20 x 1.5 cable entry, and the switch can be installed in any orientation.
