DESCRIPTION
The Hall Effect speed sensor (PSAH) is ideal for sensing steel gears or other
ferrous targets from 0 to 10 KHz. This sensor does not have a minimum
threshold speed as does a magnetic pickup sensor. However, when the sensor is
first powered up, the output state is indeterminate (Hi or Lo) when the sensor is
not detecting metal. The unit operates from a +8 to +30 VDC power supply and
is reverse polarity protected. The sensor face can be mounted flush into metal
panels. The case is stainless steel and is supplied with 10 feet (3 M) of cable.
The stranded shield wire is not connected to the sensor circuit or case.

TARGET SIZE
The PSAH can detect gears as small as 24 D.P. or other ferrous targets with
equal or greater dimensions. The sensor is compatible with all Red Lion
Controls Sensing Gears.
3/4" DIAMETER CYLINDRICAL SENSOR MOUNTING
The PSAH and other Red Lion Controls 3/4" dia. cylindrical pickups may be
easily mounted using Model 5400100 Block Mount (see diagram below). This
machined block of solid
aluminum provides for
rigid mounting using the
two included #8-32 x 1/2"
screws. The single screw
split-clamp design allows
for easy adjustment of the
airgap and locks the unit
securely without
