DESCRIPTION

LOGIC MAGNETIC PICKUPS (LMP’s) provide sensing sensitivities

several orders of magnitude greater than standard magnetic pickups when
detecting moving ferrous targets. By locating a high gain pre-amplifier & signal
processing circuit “inside” the mag pickup housing, larger airgaps and slower
target surface speeds can be achieved thereby greatly expanding application
versatility as compared with conventional mag pickups. In addition, these units
have excellent noise immunity and a frequency response to 10 KHz. The stainless
steel sensing pole is mounted flush to the plastic sensing face allowing greater
ease of setting airgaps and eliminating snagging the pole with a moving target.

Two output types are available (see ordering information). The NPN Open

Collector Transistor Output unit provides a negative going current sinking
output with the approach of a ferrous target and is current limited to 40 mA.
The Transistor Emitter-Follower Output unit provides positive going 5 V
pulses with the approach of a ferrous target and can source 20 mA of load
current. The Open Collector units are available with either an integrally potted
10, 25 or 50 foot 3-wire shielded cable with neoprene strain re lief boot or a
polarized 3-pin 5/8"-24 threaded connector for quick change versatility (see
following page for mating extension cable). The Emitter-Follower output unit is
available in the 3-pin connector version only.

This cable and connector assembly (see diagram below) is composed of PVC
jacketed, 3-wire 22 AWG conductors with stranded shield and 100% foil shield
coverage for noise immunity and is oil and water resistant. Connector/cable
junctions are silicone sealed. The 5/8"-24 threaded ring is fitted with an O-ring to
make a moisture proof connection. Cable is available in 10, 25, or 50 foot lengths.

to 3-pin connector. Shield may be connected to instrument common for
increased noise immunity.

3/4" DIAMETER CYLINDRICAL SENSOR MOUNTING

Logic Magnetic Pickups 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 one screw split­clamp design allows for easy adjustment of airgap and locks the unit securely
without deforming the case.

The PLUG MOUNT (see diagram below) allows 3/4" dia. cylindrical

sensors to be mounted in “thru-wall” applications. The Plug Mounts 3/4-14 NPT
thread is installed into a threaded wall or casing. The sensor is then installed
through the plug mount. The sensor-to-target airgap is adjusted and the sensor
is tightened into position by two #8-32 set screws. Tightening the ferrule nut
compresses a teflon ferrule around the sensor providing an oil tight seal. Plug
Mounts are available in both steel and stainless steel (see ordering information).
