The 2NC slow-action contacts break on plunger depression, giving positive-opening behavior for safety circuits. Termination is via screw terminals; insulation voltage is 600 V. Switching current is 2 A AC at 400 V AC, and 400 mA DC at 250 V DC. The 18.6 N operating force is firm enough to resist vibration false trips but not so high it requires a heavy cam. The metal housing and IP67 rating mean it survives coolant spray and dust on machine tools or conveyor lines. Lifecycle stage is listed as mature. This part is not in active phase-out but is well into its production run. Sourcing is via RFQ — quoted to order through our supply channel. No official successor has been published.","metaTitle":"D4B4A70N Limit Switch, Plunger, 2NC, IP67, 600 V","metaDescription":"D4B4A70N D4B series limit switch with plunger actuator, 2NC slow-action contacts, IP67 metal housing. 600 V insulation voltage, 2 A AC / 400 mA DC switching.
