It warns of a 'dangerous' situation when heavy machinery like forklifts gets too close to people.

The "Worker Proximity Detection System" by Yoshikawa Industries supports the awareness of heavy machinery and workers, aiming to reduce the risk of contact. By installing a "detection device" on the heavy machinery and having the worker carry a "tag," an alarm will sound when the two come within a certain distance (which can be set). 【Features】 - One detection device can detect in 360 degrees (all directions). - The detection range can be set from 3m to 12m in 1m increments. - It detects by circumventing obstacles, so it also alarms for head-on approaches. - Alarms can be activated for both the heavy machinery and the worker (please choose a tag with alarm functionality). - It can be installed regardless of the manufacturer, type, or power source of the forklift (compatible with 12v/24v/48v). - The system and peripheral devices can be developed and customized according to customer requests. - With a variety of optional products, you can use it more comfortably! - By using the "Non-Detection Area Setting Device," you can designate the driver's seat as a "non-detection area." This allows for use without removing or turning off the tag, making it popular in environments where drivers change frequently.

basic information

**About the Operation** (1) The detector is installed on heavy machinery, and the tag is carried by a person. (2) An alarm will sound when the tag enters the detection range. (3) The detection range (detection distance) can be set between 3 to 12 meters. (4) To adapt to various sites, we offer a wide range of optional products. **In response to your requests, we have added to our lineup** - Released a slim tag with an alarm function! (This is a tag with an alarm function that can be attached to a helmet.) - Released a "Non-Detection Area Setting Device" that allows you to ride heavy machinery while carrying the tag! Previously, when a person carrying a tag got on a heavy machine with a detector, the alarm would trigger in response to the tag held by the operator. However, by using this "Non-Detection Area Setting Device," you can prevent the alarm from sounding only in the driver's seat. *Many achievements in steel mills *Dustproof and waterproof types are available as standard. In addition to this, we support your site with a rich lineup. *Detection distance may vary depending on the installation environment and surrounding conditions. We have demo units available for rental, so please feel free to contact us.

Release of "Tag Possession Detection Device" to prevent forgetting to attach the (NEW) tag.

  • Product news

We are pleased to announce the new release of the "Tag Detection Device," which alerts individuals entering the workplace without a tag, as a peripheral device for the Worker Proximity Detection System! This device detects and warns when someone without a tag attempts to enter the workplace (a specific area) within systems like the Worker Proximity Detection System. By installing the device at stairs or corridors leading to the workplace, workers can easily check by simply passing through. Since it operates as a standalone unit, there is no need for complicated installation work. (It can also be used connected to a network.) Not only can it be utilized as an option for the Worker Proximity Detection System, but it can also be applied for other purposes. At Yoshikawa Industries, we can develop and customize products according to our customers' needs, so please feel free to contact us. ◆Contact◆ TEL: 093-671-8660 mail: rfsol@ykc.co.jp

Starting with operations at the steelworks, Yoshikawa Industries has reached its 100th anniversary. We continue to take on challenges that break away from existing frameworks. As a challenge outside the steel industry, we established a dedicated manufacturer, Yoshikawa Industries RF Semiconductor Co., Ltd. (1999), and provide a total solution from chip design to tag manufacturing and system integration. Leveraging our 100 years of on-site know-how and expertise in RFID, we will engage with your site through "ICT × Safety × RFID." If you have any issues at your site, please feel free to contact us.
