Model SM300 Series

nnnn

The world's first 12 mm

nnnn

and flat-profile, fast

nnnn

response, multi-material

nnnn

ultrasonic, proximity

nnnn

sensor... the efficient

nnnn

solution to close-up

nnnn

sensing

nnnn

Use the highly versatile

nnnn

SUPERPROX® Model SM300 se-

nnnn

ries of proximity sensors as a re-

nnnn

placement for inductive proximity

nnnn

sensors and fixed-field photoelec-

nnnn

tric sensors. Its long range, small

nnnn

size, fast response, performance,

nnnn

reliability, and low cost, offers a

nnnn

simple, easy to use,once-and-for-

nnnn

all solution to many of the prox-

nnnn

imity sensing problems encoun-

nnnn

tered daily in almost every indus-

nnnn

try.

nnnn

The SM300 proximity sensor

nnnn

provides reliable detection of ob-

nnnn

jects up to 102 mm (4") from the

nnnn

sensor face, performance un-

nnnn

matched by other proximity sen-

nnnn

sors of the same size or larger.

nnnn

At this distance, the sensor is

nnnn

safely out of harms way, that is

nnnn

an especially important cost sav-

nnnn

ings benefit. Easy to install, the

nnnn

SM300 is available in two differ-

nnnn

ent housing styles: the 12 mm

nnnn

threaded barrel or the flat-profile

nnnn

housing both available in ULTEM®

nnnn

plastic. As with all SUPERPROX®

nnnn

sensors, cable and connector

nnnn

styles are available.

nnnn

The SM300 is inherently ca-

nnnn

pable of automatically detecting

nnnn

all materials regardless of color,

nnnn

shape, and composition (trans-

nnnn

parent or opaque, liquid or solid)

nnnn

including clear glass, mirrors,

nnnn

wood, powder, ink, ferrous and

nnnn

nonferrous metal, plastics, and

nnnn

objects that change colors. While

nnnn

some sensors require adjustment

nnnn

(through the use of a sensitivity

nnnn

potentiometer) to the material

nnnn

they are detecting, the SM300 de-

nnnn

tects most materials automati-

nnnn

cally. With protection ratings of

nnnn

NEMA 4X (indoor use only) and

nnnn

IP67, the sensor resists most ac-

nnnn

ids and bases and is compatible

nnnn

with many chemicals, cleaning

nnnn

solutions, and chemical-based

nnnn

products. The SM300 sensor

nnnn

series is CE certified.

nnnn

These are just a few of the ben-

nnnn

efits of this new, small, multi-

nnnn

material, extended-range proxim-

nnnn

ity sensor from the world leader

nnnn

in ultrasonic sensing technology.

nnnn

The applications suited to

nnnn

the SM300 proximity sensor are

nnnn

as broad as the benefits just men-

nnnn

tioned. And because of the

nnnn

sensor's versatility, it is a solid

nnnn

candidate for a large number of y

nnnn

proximity sensing and non-con-

nnnn

tact switching needs in the plant.

nnnn

The SM300 can detect positive

nnnn

stop and true home positions for

nnnn

servo-control systems and tool

nnnn

and parts presence in automated

nnnn

CNC centers and assembly

nnnn

equipment. It is an ideal solution

nnnn

for sensing part and pin presence

nnnn

and punch-through verification in

nnnn

stamping dies. Other applica-

nnnn

tions include die open and close

nnnn

detection in stamping, plastic in-

nnnn

jection molding, die casting ap-

nnnn

plications, and many other ap-

nnnn

plications where traditional prox-

nnnn

imity sensing methods cannot re-

nnnn

liably detect the large variety of

nnnn

materials running through the pro-

nnnn

cess or they are limited by sens-

nnnn

ing range.

nnnn

Operation

nnnn

The SM300 series is a self-con-

nnnn

tained, pulse-echo, proximity

nnnn

sensing device that both trans-

nnnn

mits and receives sonic energy

nnnn

within an operating distance of

nnnn

6 mm (0.25") to 102 mm (4").

nnnn

The sensor combines the latest

nnnn

piezoelectric and microprocessor

nnnn

technology for the best possible

nnnn

performance in almost any sens-

nnnn

ing application.

nnnn

This 500 kHz proximity sensor

nnnn

operates on 12 to 24 VDC and is

nnnn

equipped with both sinking (NPN)

and sourcing (PNP) outputs. The

nnnn

sensor has two status LEDs: a

nnnn

green LED indicates "power on"

nnnn

when no object is present, and

nnnn

an amber LED indicates object

nnnn

presence, regardless of output

nnnn

state (N.O. or N.C.). Just one LED

nnnn

is illuminated at any given time.

nnnn

During operation, the sensor

nnnn

transmits to and receives sonic

nnnn

pulses from objects in front of it

nnnn

without interruption. A discriminat-

nnnn

ing microprocessor makes it pos-

nnnn

sible for the sensor to accept only

nnnn

those pulse echoes received from

nnnn

objects within the fixed sensing

nnnn

window limits and ignore all other

nnnn

objects. An object is detected

nnnn

when it is within the fixed sens-

nnnn

ing window.
