The HS9Z-A52 is a compact actuator accessory for IDEC door interlock switches, specifically engineered for hinged door applications. It features adjustable mounting with M4 hex socket head cap screws and is compatible with HS5E/HS5B series interlock switches. The actuator supports minimum door hinge radii of 170 mm (when door hinge is on the extension line of the interlock switch surface) and 230 mm (when door hinge is on the extension line of the actuator mounting surface), with additional configurations for horizontal and vertical swing applications. Installation requires a recommended tightening torque of 2.0±0.2 N·m (approximately 20±2 kgf·cm) using 2 pcs of M4 hex socket head cap screws. This actuator is commonly used in industrial safety applications where mechanical door locking is required during machine operation, providing reliable actuation for safety-critical door interlock systems.
