Square D By Schneider Electric 9007-SGSIDK Limit Switch

The Square D Gate Gard 9007-SGSIDK is a safety‑critical, self‑contained limit switch that verifies a closed safety gate or machine door before a cycle can occur, using a passive key that activates the switch without physical contact. Alignment arrows and prewired construction simplify installation, and when properly aligned the system allows up to a 0.25 inch key‑to‑switch gap, with tolerance for slight offsets as part of its design. It operates on 10–30 VDC and up to 0.5 A, housed in a nonmetallic, oil‑tight enclosure built to NEMA Type 13 standards for industrial environments, and features three LEDs (power, fault, load) to indicate status while protective circuitry can lock the switch off under fault conditions. Typical applications include safety interlocks for press guards, control panels, security access doors, and plastic injection machines where the presence of the mating key is required for the machine to cycle.
