BLOCK INDUCTIVE
PROXIMITY SENSORS
The Altech Inductive Pr oximity
Block Sensor family has a wide
selection of housings, with both
fixed and adjustable sensing range.
Units are available in DC, AC and
AC/DC operating voltages.
OUTPUTS NORMALLY OPEN (NO)
OR NORMALLY CLOSED (NC)
AC – NO, NC. DC– NO, NC
FLUSH MOUNT VS.
NON-FLUSH MOUNT
Block Sensors that are flush mount
and have electromagnetic fields
directly in fr ont of the sensing head
may be mounted directly into metal
without causing a false output. The
sensing head must be clear or any
non-target metal.
Block sensors that are Non-Flush
mount have electromagnetic fields
with a wide sensing angle. Therefore
care must be taken to ensur e that no
non-target metal comes in contact
with the sensing head.
See Figure 11 for mounting details.
OUTPUT CONNECTIONS
Block sensors are available in 2
meter fixed PVC output cables,
quick disconnect connector, or 1/2”
14NPT hole opening for wiring to a
terminal block. Please see selection
guide on pages 82-83 and the
product specification for mor e infor-
mation.
