MINI-BEAM®SM312FV

Visible-light Glass Fiber Optic DC Sensors

Printed in USA 05/01 P/N 03510 rev. C

•Used with Banner Glass Fiber Optic assemblies for specific

applications including the following: color registration

sensing in the diffuse mode (except for red-on-white

contrast, which requires a green or blue light source);

presence sensing of translucent materials and registration

mark sensing on clear webs in the opposed mode

• Compact, modulated, self-contained fiber optic sensors for

10-30V dc operation

•Useable in opposed, retroreflective, and diffuse fiber optic

modes with Banner glass fiber optic assemblies

•Switch-selectable for light operate or dark operate

•Includes Banner’s exclusive AID™ alignment system;

US patent number 4356393

*NOTES:

i) 9 m (30') cables are available by adding suffix “W/30” to the model number of any cabled sensor (e.g., SM312FV W/30).

ii) A 150 mm (6") long pigtail cable with attached QD connector is available by adding suffix “QDP” to the model number of any

MINI-BEAM sensor (e.g., SM312FVQDP). See page 5 for more information.

iii) A model with a QD connector requires an accessory mating cable. See page 5 for more information.

iv) May be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the model numbers

(e.g., SM312FVMHS). This modification reduces sensing range (and excess gain).

*Note regarding Light/Dark operate switch:

• Turn switch fully clockwise for light operate (sensor outputs conduct when

sensing light is received)

• Turn switch fully counterclockwise for dark operate (sensor outputs conduct when

sensing light is not received)

1) Install the O-ring (supplied with the fiber) on each fiber end, as shown in the

drawing.

2) While pressing the fiber ends firmly into the ports on the front of the sensor,

slide the U-shaped retaining clip (supplied with the sensor) into the slot in the

sensor’s barrel, until it snaps into place.

Lens

Lenses are sometimes added to fiber optic assemblies for extending opposed mode sensing range. Banner offers the following

lens assemblies for use with fiber optic assemblies which have 5/16" -24 threaded sensing tips (e.g. fiber model IT23S):

Lenses are most efficient when they are located slightly beyond their focal length distance from the sensing end of the fiber optic

bundle. The easiest way to focus a lens is to treat it like a magnifying glass.

Illuminate the fiber optic bundle at the threaded end of the fiber optic assembly by directing the opposite end toward a visible light

source (e.g., an incandescent bulb, visible LED, sunlight, etc.). Thread the lens onto the fiber optic assembly until the end of the

fiber optic bundle comes into sharp focus under the lens. Then, back off (unthread) the lens assembly from the point of sharpest

focus by one to three full turns. The illuminated bundle should now appear slightly blurred. This is the optimum setting, and the

lens may be secured in position using one of the jam nuts provided. Refer to the drawing above.

MINI-BEAM DC Sensor Specifications

Certifications

Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25 mA (exclusive of load)

Supply Protection Circuitry Protected against reverse polarity and transient voltages

Output Configuration Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor

Output Rating 150mA maximum each output at 25°C, derated to 100 mA at 70°C (derate ≈1 mA per °C)

Off-state leakage current less than 1 microamp

Output saturation voltage (PNP output) less than 1 volt at 10 mA and less than 2 volts at 150 mA

Output saturation voltage (NPN output) less than 200 millivolts at 10 mA and less than 1 volt at 150 mA

Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs

Output Response Time Sensors will respond to either a “light” or a “dark” signal of 1 millisecond or longer duration, 500 Hz max.

0.3 millisecond response modification is available. See note below.

100 millisecond delay on power-up: outputs do not conduct during this time.

NOTE: DC MINI-BEAMs may be ordered with 0.3 millisecond on/off response by adding suffix “MHS” to the

model numbers (e.g., SM312FVMHS). This modification reduces sensing range (and excess gain).

Repeatability 0.3 milliseconds. Response time and repeatability specifications are independent of signal strength.

Adjustments LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw GAIN (sensitivity) adjustment

potentiometer (clutched at both ends of travel). Both controls are located on rear panel of sensor and

protected by a gasketed, clear acrylic cover.

Indicators Exclusive, patented Alignment Indicating Device system (AID™, US patent #4356393) lights a rear-panel

mounted red LED indicator whenever the sensor sees a “light” condition, with a superimposed pulse rate

proportional to the light signal strength (the stronger the signal, the faster the pulse rate).

Construction Reinforced PBTthermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic lenses, and

stainless steel screws.

Environmental Rating Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12, and 13; IEC IP67

Connections PVC-jacketed 4-conductor 2 m (6.5') or 9 m (30') cables, or 4-pin Euro-style quick disconnect (QD)

fitting are available. QD cables are ordered separately. See page 5.

Operating Temperature Temperature: -20° to +70°C (-4° to +158°F)

Maximum relative humidity: 90% at 50°C (non-condensing)

Application Notes The NPN (current sinking) output of dc MINI-BEAM sensors is directly compatible as an input to Banner

logic modules, including all non-amplified MAXI-AMP and MICRO-AMP modules. MINI-BEAMs are

TTL compatible.

MINI-BEAM Modifications

Description

All MINI-BEAM sensors may be ordered with an integral 9 m (30')

cable in place of the standard 2 m (6.5') cable

Standard dc MINI-BEAM sensors with 1 millisecond output response may

be modified for 0.3 millisecond (300 µs) response.

NOTE: Faster response comes at the expense of lower excess gain.

Also, operating temperature range becomes -20º to +50ºC (-4º to +122ºF)
