№ Term Meaning
1 Detector
It has a transmit function by a magnetic field, and an alarm function by receiving
a radio signal from a TAG.
It has a function to receive the magnetic field from the detector and a function to
transmit radio waves.
ALERT-TAG has a function to alert you.
The magnetic field transmitted by the detector uses the 125kHz band.
Stable sensing distance is achieved by using a magnetic field.
The radio waves transmitted by the TAG use the 315MHz band.
Transmitting radio waves from the TAG to the detector enables the detector to
alert.
They are used to define levels of sealing effectiveness of electrical enclosures
against intrusion from foreign bodies (tools, dirt etc.) and moisture. As defined by
International Standard EN 60529.
IP6 * [0 to 6] Dust-proof
6: Dust does not enter the inside.
IP*5 [0 to 8] Waterproof
5: low-pressure jets (6.3 mm) of directed water from any angle
Noise that affects the radio waves received by the detector.
In places where radio noise is present, the sensing distance that the detector alarms
may be shortened.
Noise affecting the magnetic field received by the TAG.
In places where magnetic field noise is present, the detection distance of the TAG
may be shortened.
Ex.
the power distribution boards, factory equipment
and large motors.
Indicates the unit of sound volume.
Ex.
・ 90dB: Bulldozer, etc. in a noisy plant
・ 110dB: Automobile horn, etc.
12 dB
