POLARIZING FILTERS
As light is polarized by a transparent film or membrane, CX-491
detect an object covered or wrapped by transparent film. Such objects
include, for example:
Can wrapped by clear film
Aluminum sheet covered by plastic film
Gold or silver (glossy) labels or wrapping paper
In such cases, take the following steps.
1 Tilt the sensor with respect to the object to be sensed.
2 Reduce the sensitivity.
3 Increase the distance between the sensor and the object to be sensed.
9 SLIT MASKS
The slit mask is only available for the thru-beam type sensor.
Optional slit masks help the sensor detect small objects. However, the
sensing range is reduced.

10 INTERFERENCE PREVENTION FILTERS
Interference prevention filters are only available for the thru-beam
may not
type sensor.
By mounting interference prevention filters, two sets of thru-beam type
sensors can be mounted close together. However, the sensing range is
reduced.
The filters can be mounted using the same method as for slit masks. For
details, see page 4, section 9, SLIT MASKS.
For interference prevention to work, the following conditions must be
met.
The two sets of sensors must be fitted with different types of interference
prevention filters.
Filters must be mounted on emitters and receivers.
