A magnetic sensor with a switch function that responds to opening and closing, and a magnetic force retention function for doors and lids!
This is a magnetic sensor composed of a reed switch, magnet, and yoke, integrating a switch function that responds to opening and closing, along with a holding function for doors and lids using magnetic force. By controlling an advanced magnetic circuit, it performs ON/OFF operations of electrical contacts, providing signals corresponding to the opening and closing of doors and lids. Unlike contact-type mechanical switches, the switch part does not suffer from wear-related failures and excels in durability, safety, and reliability. 【Features】 ■ The switch is ON/OFF controlled by internal magnetic control ■ Equipped with both door locking and opening/closing switch functions ■ Compact design with a small mounting area, ideal for compact equipment ■ High reliability due to the use of a reed switch in the electrical contact section ■ Guaranteed for 100,000 openings and closings ■ Contact operation available in two types: NC (Normally Closed) and NO (Normally Open) ■ Flat adsorption surface ■ Large contact capacity expands circuit configuration options ■ Can be screwed from two directions: horizontal and vertical *For more details, please refer to the PDF document or feel free to contact us.
