The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Full and empty management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, achieving efficient parking lot operations. ■ For large parking lots, the "floor management method" and "block management method," which focus on cost reduction, are recommended. Sensors are installed at regular intervals to count the number of vehicles passing through. This method offers the advantage of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 ■ For smaller scale operations, the "space management method," which installs sensors in each parking space to display availability with high accuracy, is recommended. By ensuring accurate full and empty displays, it helps prevent unnecessary entry of new vehicles and enables safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8

We will introduce the implementation results of the sensor technology developed by the Hotron Group, which has been cultivated over more than half a century, through customer case studies. In addition to automatic door sensors, we also offer a wide range of vehicle detection sensors and nursing/care sensors. We have many implementation examples available, so please take a look at the case study page.
