The "Hotron Non-Contact Switch" allows you to open and close doors without directly touching door knobs or switches, making it hygienic! You can choose from two types: the "Hand Wave Sensor," which only requires you to wave your hand, and the "Foot Switch," which only requires you to place your foot in front of it. It reduces the risk of virus and bacteria transmission in places where hygiene is a concern, such as food factories, restaurants, hospitals, and nursing facilities. 【Features】 ○ Reduces the risk of virus transmission by allowing door operation without contact ○ A wide variety of options to choose from based on application and location ○ Ideal for places where hygiene is a priority, such as food factories and medical facilities ○ Prevents unnecessary detection due to the switch mechanism 【Product Lineup】 ■ Hand Wave Sensor Series ○ Exposed waterproof type, front, down, and side-facing type "PF-R5" ○ Exposed type, front-facing type "PF-R1" ○ Embedded type, front-facing type "PF-U2" ○ Exposed type, downward wide type "PF-R4" ■ Foot Switch Series ○ Slim type with wide opening, vertical beam type "PF-01S" ○ Slim type with wide opening, horizontal beam type "PF-03S" ○ Standard type, horizontal beam type "PF-05" ◎ For more details, please download the catalog or contact us.

In recent years, with the outbreak of infectious diseases, there has been a demand for products that cater to "contactless operation," and this trend has extended to environments where automatic doors were previously operated by touch switches. As the automation of doors and the non-contact operation of automatic doors become more widespread, do you have any of the following concerns? ☑ Although automatic doors have been installed, they remain open due to people crossing frequently in busy areas. ☑ Touch switches have been introduced to reduce unnecessary openings and closings, but hygiene is a concern. ☑ Touch switches require regular battery replacements since they are powered. The light beam touch sensor "HA-T401" opens and closes automatic doors without contact, and its compact detection range makes it suitable for narrow passages and busy areas, contributing to energy savings and infection control. 【Benefits of Implementation】 ○ Adaptable to various door types with four spot settings, ideal for busy roads and narrow passages. ○ Energy-saving effects with two setting modes that reduce unnecessary openings and closings of automatic doors. ○ Equipped with a light beam touch function, allowing doors to open and close simply by waving a hand, ensuring hygiene. ◎ For more details, please download the catalog or contact us.
