The ESPE SLM11 Series safety door switch is an industrial safety interlock designed to monitor guard doors, access panels, hinged doors, and safety fences on automated machinery. Available in models with 2 contacts or 4 contacts, it offers high holding force up to 1300 N, IP67 dust‑proof and water‑resistant protection, and robust construction for reliable operation in harsh industrial environments. These switches support both general load and micro‑load applications, feature rotatable actuator head and multiple key orientations for flexible installation, and are compliant with international safety standards for door monitoring to ensure safe machine access control.
Both the 2‑contact and 4‑contact variants carry CE and TÜV certification and meet standards such as EN 60947‑5‑1, EN ISO 14119, and IEC/GB safety norms, making them suitable for a wide range of industrial guarding and safety monitoring tasks where reliable door position feedback is required.
