and SE3470/5470 infrared emitters

Benefits:

Photodarlington mounted in a

TO-46 metal-can package. Glass-lensed

can provides a narrow acceptance

angle. Often ideally suited for operation

in hostile environments. Applications

include presence sensing, motion

sensing, position encoding, limit sensing,

movement detection, and counting.

SDP8105.

Features:

T-1 plastic package • 20°

(nominal) acceptance angle • Consistent

optical properties • Mechanically and

spectrally matched to SEP8505 and

SEP8705 infrared emitters

Benefits:

Photodarlington transfer molded

in a T-1 package to minimize effect of

visible ambient light. Transfer molding of

this device provides enhanced optical

centerline performance. Lead lengths

are staggered to provide a simple

method of polarity identification. Potential

applications include presence and motion

sensing, position encoding, limit sensing,

movement detection, and counting.

SDP8106.

Features:

SEP8506 and SEP8706 infrared emitters

Benefits:

Photodarlington molded in a

side-looking black plastic package to

minimize effect of visible ambient light.

Chip is positioned to accept radiation

through a plastic lens from the side of

the package. Potential applications

include presence sensing, motion

sensing, position encoding, limit sensing,

movement detection, and counting.

SMD2420.

Features:

Small ceramic packages

• Glass-lensed optics for efficient optical

coupling • Upright or inverted mounting

capability • Low profile, small size for

flexible layout of multiple channels

and custom arrays • Compatible with

automated solder processes • Choice of

photodiode or phototransistor detectors

• Infrared emitter features high power

dissipation capability • Tape and reel

packaging option (pick/place machine

compatible)

Benefits:

Lens minimizes cross-talk and

often eliminates the need for apertures in

non-critical applications. May be mounted

on the printed circuit board, lens up or

inverted, allowing flexibility in layouts for

multiple channel and custom arrays. Often

useful in potential applications requiring

linear response or high switching speed.

Potential applications include optical

encoders for motion control, computer

peripherals, vending and point-of-sale

applications, smoke detectors, and

medical equipment.

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.
