Reliability and durability over time: thanks to the housing in aluminium with polyester paint finish, resistant to atmospheric agents. Safe: obstacle detection system and monitoring of the motor absorption during movement, self-diagnosis by means of a flashing light, courtesy LED light. The latest generation optical and resistive 8.2 Kohm sensitive edges can also be connected. Two irreversible 24 Vdc versions with limit switches on opening and closing: with built-in control unit (HK7024) and without control unit (HK7224). Practical and quick installation: the articulated arm is adjustable in length for maximum flexibility. Simple and precise limit switch adjustment: mechanical stops and micrometric adjustment screws. Easy to operate release lever: with metal lock and personalised Nice key. With provision for cable control.
