Responding to customer feedback, back again! "Keiko-chan 7UX" released! USB bus-powered and easy-to-use warning light.

USB bus power & easy-to-use warning light "Keiko-chan 7UX" USB connection (DN-1770UX) and USB/DI connection (DN-1780UX)

In August 2022, the "Keiko-chan 4UX" three-light model was discontinued, and in response to the long-awaited requests from repeat customers, its successor has been decided for release. This warning light, popular for its ease of use with power supply and control via USB cable, retains the basic functions of the 4UX. The 7UX now offers two new types to choose from: a USB connection only type (DN-1770UX) and a USB/contact input (DI) connection type (DN-1780UX). In addition to use in offices, call centers, medical and nursing fields, and factories, there has been an increasing demand for its use in offices, conference rooms, and management rooms where people are not always present. The "Keiko-chan 7UX" contributes to improving operational efficiency, productivity, cost reduction, and working environment enhancement. For the one-light model, you can use the compact palm-sized warning light DN-1600 series "Anywhere Keiko-chan USB" or "Anywhere Keiko-chan USB+DI" model. == For more details, please contact us. ==

An article has been published about the case of introducing the expense reimbursement system "Rakuraku Seisan" at TSP Corporation. ~ In the case of TSP ~ Before the introduction, there were challenges such as dealing with the "paper" sent from various locations and the reliance on specific individuals for the tasks. After the introduction, the input and checking of FB data, which used to take 2 to 3 hours, can now be completed in just 5 minutes. Additionally, the mindset of the accounting department, which was previously reliant on manual entry, has changed. [Case Overview] ■ Challenges before introduction - Dealing with "paper" sent from various locations, reliance on specific individuals ■ Key points of introduction - A robust support system for setup and operation - Easy to start from a small scale both financially and functionally *For more details, please refer to the related links or feel free to contact us.

The facility operating the nurse call system has made the bed exit sensor wireless, allowing it to notify in conjunction with the nurse call. By simply connecting the mat sensor "Foldable Thin Matt-kun," the body movement call "Ugo-kun," and the wheelchair body movement call "Ayumi-chan" to the transmitter HB-RS, you can make the bed exit sensor wireless. The infrared sensor "Just Place Pole-kun" has the transmitter HB-RS built-in. 【Features】 ○ Wireless conversion by simply connecting existing sensors to the transmitter HB-WSK. ○ The bed exit sensor notifies wirelessly in conjunction with the nurse call. ○ Up to 5 transmitters can be registered with one receiver. ○ The communication distance between the transmitter and receiver is approximately 10 meters. ◎ For more details, please contact us or download the catalog.

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
