Uncommon sense. Honeywell Sensing and Control (S&C)
offers environmentally sealed proximity sensors in a variety of
technologies — including Eddy Current Killed Oscillator (ECKO)
and Hall-effect. Once a metallic object is detected in front of
the sensing face, a signal is passed through the conditioning
circuitry to give an output configured according to the sensor
application.
FEATURES
Proximity Sensors
RDS80004 Series.
Features: 2-wire dc inductive • Output
current is proportional to the applied
voltage and is designed to operate at
a nominal 16 Vdc with a 1 kOhm load
• Results in an output of 8 mA when no
wheel is detected, and 2 mA when a
wheel is detected • Available in high and
low frequency versions
Benefits: Non-contact detection of rail
wheel flanges at speeds up to 500 km/h.
Ease of installation, electrically robust.
Enhanced life, low “in track” maintenance.
Supports extended lineside transmission
distances. Facilitates use in wheel
detection systems and fault diagnosis.
Potential applications include train
detection (presence, direction, speed),
train direction detectors, and train axle
counters.

RDSA Series.
Features: Train detection without track
circuits • Directional and non-directional
operating modes • Requires two wheel
detections to validate train presence
• Solid state technology • Self monitoring
• Can detect train direction or position
• Can detect sensor and power supply
faults
Benefits: Enhanced reliability. Reduces
risk of error. Often eliminates problems
with leaves, rust, snow, salt, grit, dust,
and oil on rails. No rail cutting, drilling, or
insulation is required if clamps are used.
Can be installed in parallel with the old
system, creating minimal changeover time.
Potential applications include crossing
gate closure on train approach (non
fail-safe), train detection for monitoring
systems, and wagon location/direction in
marshalling yards.

These rugged, one- or two-piece products are designed to
meet demanding temperature, vibration, shock, and EMI/EMP
interference requirements, and are available in a number of
housing materials and termination styles. Multiple potential
applications are found in the harsh environments of aerospace
(landing gear position, doors and slides, monitoring systems),
ordnance (projectile sensing, ammunition loading systems) and
marine (submarine hatch and door position, offshore equipment).
