or greater shielded multi-core cables (JIS CVV-S) are recommended. Be sure to ground the shielded cable on the
device (connected to the Neosensor) side.
The maximum cable length is 100 m.
Notes for signal line connection
Induction current can flow from the Neosensor (humidity sensor, temperature/humidity sensor models) to the controller input
circuit, and inadequate time constant of the controller can generate noise. To prevent such things, see the following.
No problem will occur for connecting Neosensor to our controller.
Provide a controller with low pass filter (40 dB or higher removal ratio in normal mode) that receives signals from
Neosensor.
For insufficient removal ratio, provide an isolator on the controller input line.
IMPORTANT:
When Neosensor is faulty, reduced output may cause over-humidification. Provide safety measure against
over-humidification.
Corrosive gas or organic solvent can cause sensing error, shorten the service life, or damage the Neosensor.
Before using Neosensor in abnormal atmosphere, consult with our salesperson.
