AC Hookups
Supply Voltage and Current 24 to 250V ac (50/60 Hz), except for SMA91E, ESR and EF emitters, which operate from 10 to 250V ac or dc
Supply Protection Circuitry Protected against transient voltages
Output Configuration SPST SCR solid-state relay with either normally closed or normally open contact
(light/dark operate selectable); 2-wire hookup
Output Rating Minimum load current 10 mA, max. steady-state load capability 750 mA to 50° C ambient (122° F),
500 mA to 70° C ambient (158° F)
Inrush capability: 4 amps for 1 second (non-repetitive)
Off-state leakage: current less than 1.7 mA rms
On-state voltage drop: ≤ 5 volts rms at 750 mA load, ≤ 10 volts rms at 15 mA load
Output Protection Circuitry Protected against false pulse on power-up
Output Response Time Receivers only: 8 milliseconds 0N and 4 milliseconds OFF, independent of signal strength
All other models: 8 milliseconds ON and OFF
OFF time does not include load response of up to 1/2 ac cycle (8.3 milliseconds).
Response time specification of the load should be considered when total response time is important.
NOTE: 300 millisecond delay on power-up; outputs do not conduct during this delay.
Repeatability Opposed and Glass Fiber Optic Emitter-Receiver pairs: 1.0 millisecond
Retro, Diffuse, Convergent and Glass Fiber Optic: 2.6 milliseconds
Adjustments Light/Dark Operate select switch and Sensitivity control potentiometer, both located at rear of sensor
Indicators Top-mounted red LED indicator lights when output is conducting.
Model SMA91E and SM91ESR emitters: visible-red “tracer beam” indicates “Power ON” and enables line-of-
sight alignment.
Construction Reinforced thermoplastic polyester housing, totally encapsulated, molded acrylic lenses and stainless steel
hardware
Environmetal Rating Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 12 and 13; IEC IP66
Connections PVC-jacketed 2 m (6.5') or 9 m (30') cables or 3-pin Mini-style (QD) fitting available. See page 7.
Operating Conditions Temperature: -20° to +70° C (-4° to +158° F) Maximum relative humidity: 90% at 50° C (non-condensing)
Application Notes i) 912 Series ac sensors can be destroyed from overload conditions.
ii) Use on low voltage 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.
