Installation

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

150 mA 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): < 1 volt at 10 mA, < 2 volts at 150 mA

Output saturation voltage (NPN output): < 200 millivolts at 10 mA, < 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 “dark” signal of 1 millisecond or longer duration,

500 Hz maximum. Modification for 0.3 millisecond response is available (MHS-suffix

models; these models also feature reduced sensitivity range and reduced repeatability.)

NOTE: Outputs are non-conducting during 100 millisecond delay on power-up.

Repeatability

Opposed: 0.14 milliseconds

Non-Polarized and Polarized Retro, Diffuse, Convergent, Glass Fiber Optic, and

Plastic Fiber Optic: 0.3 milliseconds

Response time and repeatability specifications are independent of signal strength.

Adjustments

Light/Dark Operate Select switch

15-turn slotted brass screw Gain (sensitivity) adjustment potentiometer (clutched at both

ends of travel)

Located on the rear panel, protected by a gasketed, clear acrylic cover.

Indicators

Patented alignment Indicator Device system (AID™, US patent #4356393) lights a rear-

panel-mounted LED indicator when the sensor sees light. Its pulse rate is proportional to

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

Construction

Reinforced thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic

lenses, 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 QD fitting;

QD cables available separately.

Operating Conditions

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

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

Application Note

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.
