Fail-safe sensors
August 1st 2008 Ifm electronics has
expanded its range of
inductive sensors which
achieve SIL2 or SIL3.
Available in M12 (SIL2)
or M18, M30 and cube
styles (SIL3) and designed
with two OSSD's (output
signal switching devices)
built in, the new fail-safe
series will work with
conventional safety relays,
and with safety plc's.
No special demands such
as shielding, twisted wires
or separate laying are
placed on the industrial
standard M12 connection.
The sensor is simply
connected to existing
evaluation units, safety
controllers and safe bus
systems using a common
unscreened 4-core cable. More articles from ifm electronic Limited: |
