Description
Bulletin 46DFA PHOTOSWITCH® DIN rail fiber-optic amplifier is a
dual display that is designed for the detection of objects with the use of a
standard 2.2 mm (0.09 in.) diameter fiber-optic cable. These sensors are
ideal for assembly and packaging applications where you detect objects
in limited spaces or applications that require high speeds. Additional
sensing flexibility can be achieved when used with the wide variety of
fiber-optic tips.
Bulletin 43G glass fiber-optic cables compatible with this amplifier are
ideal for use in high temperature applications. For continuous
movement and high-flex applications, we recommend the use of the
Bulletin 43P small aperture plastic fiber cables.
Features
• Two high-visibility displays provide configuration and operation
feedback that makes the sensor easy to set up, operate, and
maintain.
• ECO (economy) display mode reduces amplifier power
consumption by 25%.
• Teachable LED intensity provides added flexibility in
applications where there's a need to detect clear or transparent
objects.
• Fast-response output using pin 2 when connected using
IO-Link enables continuous sensor monitoring without impact
on response time needs.
• Fast response speeds of 50 µs, 500 µs, 4 ms, and 32 ms allows
operators easy adaptation of the sensor response time to their
application needs.
• Built-in totalizer feature allows operator to trigger the sensor
output once a certain count value has been reached.
• Cross-talk protection enables operation of sensors in close
proximity without an impact on performance.
