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

**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.

This system alerts both the driver and the worker when construction machinery and the worker approach each other.

(1) The detector transmits an LF band alternating magnetic field. (2) The tag held by the operator continuously sends data, including the tag's ID, magnetic field detection signal, and magnetic field strength, to the surroundings (once every few seconds). (3) Tags within the range of the magnetic field signal from the detector (up to 12m) will retransmit the magnetic field detection signal and magnetic field strength. At this time, the transmission interval is automatically adjusted to be as short as possible. (4) The detector analyzes the magnetic field strength from the tag, and if it exceeds the specified value, an alarm will sound. *This may vary depending on the installation environment and surrounding conditions.
