Multichannels |
 |
|
|
A multichannel
sensor is a sensor with alignment of several elements, enabling
magnetic information sensing on the same time axis. The main feature of
the multichannel sensor is that target media can be two-dimensionally
traced. To detect several types of media, or change the medium type,
you only need to overwrite the ROM. The standard model provides a
detecting width of 3 mm, channel pitch of 5 mm, and eight channels.
However, we can offer custom-made models with required detecting width,
number of channels, and channel pitch. For details, consult Murata

 Features |
|
- Much information can be detected on the same time
axis.
- Volume of detectable information is increased.
- Provides a shorter element pitch when compared with a
configuration where several single-channel sensors are aligned.
- Suitable for differentiating many types of bank notes
or tickets.
- Enables non-contact detection for high-speed
processing.
- Can be positioned more easily when compared with a
configuration where several single-channel sensors are aligned.

| Field-proven Performance |
|
|
The performance
of the multichannel sensor has been proven in the field where
high-precision and high-speed transport have been required. |
|
| Mounting the Sensor |
|
|
It is recommended
that the multichannel sensor be mounted with an L-type bracket. |

|
| 1. Interference between
channels |
|
|
A magnetic dot
with 1-mm diameter is placed on the sensor's detecting surface and
transported laterally in 0.5-mm steps, and the sensor's output is then
measured. |
|
 |
|
- The "0 mm" position corresponds to the center
position of the Channel 1 element. The "5 mm" position corresponds to
the center position of the Channel 2 element.

|
| Non-contact Detection |
|
|
|
Non-contact
detection is required for high-speed processing systems. |
|
| <Gap /
Output Voltage Attenuation Characteristic> |
|
 |
|
|
| (1) |
A gap of "0 mm" corresponds to the position where
the target medium is in contact with the sensor's detecting surface. |
|
|
|
- Non-contact detection reduces the mechanical load
generated in high-speed transport.
- Non-contact detection reduces the wearing of the
sensor surface.
|
|
| Wiring Savings |
|
|
The 8-channel
sensor provides 24 + 1 (FG) terminals. Using a PCB enables the required
number of terminals to be reduced to 11. |
