The SUNTES DB‑40xxEF series consists of spring‑applied, electromagnetically released disc brakes designed for fail‑safe operation. Models from DB‑4010EF to DB‑4021EF handle rotating discs ≥200 mm thick (10–20 mm) and support up to 360 cycles/hour. In power-off scenarios, built-in springs engage the brake; retraction is controlled by an electromagnetic coil powered from DC (150–210 V pull-in, 20–31 V hold). Features include optional limit switches, anti-rust plating, and vertical shaft mounting. These units are ideal for cranes, hoists, industrial vehicles, reversing equipment, and other safety-critical applications requiring reliable braking upon power loss .
