HSDL - 9100
Surface-Mount Proximity Sensor
Data Sheet
Description
The HSDL-9100 is an analog-output reflective sensor with
an integrated high efficiency infrared emitter and photo-
diode housed in a small form factor SMD package. The
optical proximity sensor is housed in a specially designed
metal-shield to ensure excellent optical isolation resulting
in low optical cross-talk.
HSDL-9100 is a class of its own with its small form SMD
package and at a detection range from near zero to 60mm.
Itisspecificallyoptimizedforsize,performanceand ease of
design in mobile constrained applications such as mobile
phones and notebooks.
HSDL-9100 has extremely low dark current and high
signal to noise ratio (SNR) where high SNR is achieved
with a pair of highly efficient infrared emitter and highly
sensitive detector.
Features
• Excellent optical isolation resulting in near zero optical
cross-talk
• High efficiency emitter and high sensitivity photodiode
for high signal-to-noise ratio
• Low cost & lead-free miniature surface-mount
package
Height – 2.70 mm
Width – 2.75 mm

Appendix B: General Application Guide for the HSDL-9100
Description
The Proximity sensor has several possible applications for
multimedia product, Automation, and Personal handled.
The proximity sensor is basically made up of the emitter
(infrared LED) and detector (photodiode). The block dia-
gram of the sensor is shown in Figure 13. The emitter will
emit IR light pulse. This light travels out in the field of view
and will either hit an object or continue. No light will be
reflected when no object is detected. On the other hand,
the detector will detect the reflected IR light when it hits
the object.
Interface to the Recommended I/O chip
The HSDL-9100 is general interface with the GPIO pin of
the controller chipset. The LED_A, pin1 is connected to the
PWM port alternatively the external timer circuitry can be
used to drive the LED. The DET_K, pin 4 is interface to the
signal conditioning before driving the GPIO port.
Figure 14 shows the hardware reference design with
HSDL-9100.
