6.2 MAGNETIC MARK DETECTOR SPECIFICATION
1. General
This specification describes the latest magnetic mark detector. It replaces the
original AMS100 detector, p/n AMS1A003. The performance characteristics
emulate the original unit.
2. Mechanical
The mark detector will work in both the original housing p/n AMS1M022 and the
AM5K versions using p/n AM5KM029. The pc board is potted to prevent
damage from shock, vibration, or humidity.
3. Power
Input power is 9 - 30vdc at 100ma max.
4. Outputs
Digital line driver out for strong & strong\ and also weak & weak\ where a weak
mark is 4 gauss or less and a strong mark is greater than 4.1 gauss measured
0.10 inch from cable surface. The signals are a +5vdc digital pulse. A digitized
0-5vdc representation of the analog signal is provided.
5. Performance
a) Operating temperature -40 to +120 f. compensated and stable. Storage
temperature -60 to +180 f.
b) Magnetic mark detection at cable line speeds of 1 to 1000 feet per minute.
c) Auto cal feature removes offset of the electronics and any constant
magnetic field less than 1 gauss every 100ms. If in a greater field, it will
auto calibrate every 11 seconds.
d) Detection of apparent zero gauss (at high/low crossing) is within 0.1 inch
and repeatable so as any error is not accumulative.
e) Will survive a gauss level exposure of 60 gauss.
