Case introduction for food factories! Introducing the non-contact switch "PF-R5" in food factories. Open and close doors only when necessary, even in narrow aisles!

ホトロン ホトロン
Introducing a case study of the implementation of a non-contact switch in a food factory! **Challenges Before Implementation** The aisles were narrow, and there were instances where the door would open when workers passed near the sensor, necessitating an urgent adjustment of the area from facing forward to downward. **Implemented Product** Non-contact switch "PF-R5" ● Easy adjustment of fine angle settings; the hand-sensing sensor opens and closes the door when the beam switch's light is obstructed. ● Angle adjustment of the beam switch in three patterns: forward, downward, and sideways! ● Hygienic as it does not require direct contact with the switch! ● Waterproof and dustproof structure. **Effects After Implementation** The direction of the arrows on the sensor surface indicates where to place your hand, making it easy to understand that it is a switch. Adjusting the area was very simple, and it was very helpful that it could be done easily by removing the cover.

Hyper CLT flooring panel

CLT flooring boards that can also be used in material yards | Hyper CLT flooring boards

  • NEW
  • PRODUCT

In a civil engineering site material yard, not only is material storage conducted, but also the frequent movement of trucks and heavy machinery, unloading, and the movement of workers. On unpaved ground, mud and ruts can occur due to rain, which may reduce work efficiency. Hyper CLT mats are civil engineering CLT materials that utilize wood CLT. By laying them in material yards or storage areas, a work space that facilitates the movement of vehicles and heavy machinery can be established while protecting the ground. They can be laid only in necessary locations, and relocation or repurposing in accordance with construction progress is also possible. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery. After use, they can also be utilized as temporary roads, access routes, or heavy machinery work yards. Additionally, they offer unique benefits of wood, such as glare reduction, noise suppression, and CO2 fixation. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," these wooden mats can also be used for environmental improvement in material yards and innovative public works.
