Infrared Sensors
Line Guide
Solid, sensitive solutions.
Optoelectronics integrates optical
principles and semi-conductor electronics — the inter-conversion
of electricity to light. In electronic systems where feedback and
control systems are common, these infrared sensors are often
critical.
Honeywell Sensing and Control (S&C) offers a broad selection of
often reliable, cost-effective, off-the-shelf optoelectronic sensor
solutions for many potential applications — including printers and
copiers, metering and data storage systems, liquid-level sensing,
motion control, scanning, automated transactions, barcode
readers, drop sensors, and other medical equipment. We also
provide a wide array of custom solutions ranging from special
electrical selections, special markings, wiring, and connectors to
completely unique housings or integrated circuits.
FEATURES
REFLECTIVE SENSORS
HOA1395.
Features:
Side-looking plastic package
• Phototransistor output • Infrared emitter
and phototransistor detector in a single
package • Low profile for design flexibility
• Designed for short-distance detection
• Enhanced sensitivity • Unfocused for
sensing diffused surfaces
Benefits:
Miniature infrared sensor
designed to sense reflective objects at
short distances. Infrared emitter and
phototransistor are mounted side-by-side
with an integral barrier to minimize cross-
talk.
HOA0149.
Features:
Phototransistor output
• Focused for maximum response
• Low-profile housing • Plastic ABS
molded housing
Benefits:
An infrared emitter and
phototransistor encased side-by-side on
converging optical axes. Phototransistor
responds to radiation from an infrared
transmitter only when a reflective object
passes within its field of view.
Benefits:
An infrared emitter and
phototransistor or photodarlington
encased side-by-side on parallel axes.
Detector responds to radiation from
infrared emitter only when a reflective
object passes within its field of view.
Potential applications include presence
sensing, motion sensing, movement
detection, and counting.
HOA1405.
Features:
Phototransistor output
• Focused for maximum response
• Ambient light and dust protective filter
• Plastic-molded components
Benefits:
An infrared emitter and
phototransistor encased side-by-side on
converging optical axes. Phototransistor
responds to radiation from an infrared
emitter only when a reflective object
passes within its field of view. Employs
an IR transmissive filter to minimize the
effects of visible ambient light and to
provide a smooth optical face which
prevents the accumulation of airborne
HOA1180.
Features:
Choice of phototransistor
or photodarlington output • Enhanced
sensitivity • Wide operating temperature
-55 °C to 100 °C [-67 °F to 212 °F] • 305
mm [12 in] min. 28 AWG PVC insulated
wire leads • Metal can packaged
components
Benefits:
Consists of an infrared emitter
and phototransistor or photodarlington
encased side-by-side on converging
axes. Detector responds to radiation from
an infrared emitter only when a reflective
object passes within its field of view.
HOA1397.
Features:
Choice of phototransistor or
photodarlington output • Low profile for
design sensitivity • Unfocused for sensing
diffused surfaces • Plastic-molded
components
Unless otherwise noted,
potential applications include printers and copiers, motion control systems, metering systems, liquid-level
sensing, data storage systems, scanning, automated transaction, drop sensors, and other noninvasive medical equipment.

Infrared Sensors Line Guide
Often reliable, cost-effective
performance.
Often ideal for object presence,
motion and limit sensing,
position encoding, movement
detection, and counting, the
Honeywell S&C infrared sensor
line consists of reflective and
transmissive sensors, detectors,
emitters, and encoders.
Reflective:
An infrared emitter
and phototransistors or
photodarlingtons are encased
side-by-side. Detector responds
to radiation from the infrared
emitter when a reflective object
passes.
Transmissive:
Through a field
of view, an infrared emitter and a
photosensor are mounted facing
each other when an opaque
object passes through the slot,
interrupting the infrared path,
it is detected. These metal or
plastic products offer a variety
of electro-optical characteristics
and package styles.
Detectors:
Available in a
number of different plastic,
metal, and ceramic packages,
with a wide variety of electro-
optical characteristics. Can
sense light over broad spectrum
from low visible through near
infrared wavelengths. Analog
detectors are available in
photodiodes, phototransistors,
and photodarlingtons. Digital
Optoschmitt detectors are also
available.
Emitters:
Available in a variety
of packages to compliment
the Honeywell detector family.
Available in transfer-molded
plastic packages, as well as
ceramic surface mount or metal
packages in various styles. Two
basic chip types are used: GaAs
and AlGaAs.
Encoders:
Sensing speed and
direction or mechanical
motion, these PC-mount, plastic
products are typically used in
conjunction with an encoder
disk or linear encoder strip. As
the interruptive pattern moves,
the sensor provides data for
processing.
