SICK ES11-SC4D8 Safety Interlock Command Device

The SICK ES11-SC4D8 Safety Interlock Command Device is a compact E-stop reset station from the ES11 family that combines an emergency stop pushbutton with an illuminated reset pushbutton in a single unit (Part number ES11-SC4D8, 6051329). Its 40 mm wide × 123 mm high × 52 mm deep enclosure houses two normally closed (NC) contacts and one normally open (NO) contact accessible via a single M12 8‑pin plug connector, with Flexi‑Loop‑ready wiring for safe-system integration. Designed for restart interlock applications in machine guarding, it includes a RESET cover and retaining clip for secure mounting and operator visibility. The device is rated for protection class III (EN 50178) and uses slow‑action switching, with a B10d life of 2.5 × 10^5 switching cycles. Electrical specifications specify a switching current range of 1 mA to 100 mA and a switching voltage of up to 1 V DC, suitable for low‑power restart signaling within safety circuits. This safety command device enables clear operator acknowledgment of faults before resumption of operations, providing a dedicated reset path after an E‑stop condition.
