MINI-BEAM

MINI-BEAM

Supply Voltage and Current

24 to 240V ac (50/60 Hz), 250V ac max

Supply Protection Circuitry

Protected against transient voltages

Output Configuration

SPST SCR solid-state relay (light/dark operate selectable); 2-wire hookup

Output Rating

Min. load current 5 mA; max. steady-state load capability 300 mA to 50° C ambient

100 mA to 70° C ambient

Inrush capability: 3 amps for 1 second (non repetitive); 10 amps for 1 cycle (non repetitive)

Off-state leakage current: less than 1.7 mA rms

On-state voltage drop:

≤ 5 volts at 300 mA load, ≤ 10 volts at 15 mA load

Output Protection Circuitry

Protected against false pulse on power-up

Output Response Time

Opposed Mode: 2 milliseconds on and 1 millisecond off;

Non-Polarized and Polarized Retroreflective, Convergent, Plastic Fiber Optic: 4 milliseconds on and off;

Diffuse and Glass Fiber Optic: 8 milliseconds on and off

“OFF” response time specification does not include load response of up to ½ ac cycle (8.3 milliseconds).

Response time specification of load should be considered when important.

NOTE: 300 millisecond delay on power-up.

Repeatability

Opposed: 0.3 milliseconds

Non-Polarized and Polarized Retroreflective, and Convergent and Plastic Fiber Optic: 1.3 milliseconds

Diffuse and Glass Fiber Optics: 2.6 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

Red indicator LED on rear of sensor is “ON” when the load is energized

Construction

Reinforced thermoplastic 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 2-conductor 2 m or 9 m cables, or 3-pin micro-style quick-disconnect (QD) fitting are available. QD

cables are ordered separately. See page 386.

Operating Conditions

Temperature: -20° to +70° C

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

Application Notes

i)

Overload conditions can destroy ac MINI-BEAM sensors. Directly wiring sensor without load series across hot

and neutral will damage sensor (except emitter models).

ii)

Low voltage use requires careful analysis of the load to determine if the leakage current or on-state voltage of

the sensor will interfere with proper operation of the load.

iii) The false-pulse protection feature may cause momentary drop-out of the load when the sensor is wired in

series or parallel with mechanical switch contacts.
