SM31E

The Mini-Beam-DC-Voltage Series offers self-contained opposed mode modulated Infrared Sensor pairs for 10 to 30 V dc operations. Standard sensor pairs have 3 m (10 ft) range and long range sensor pairs have 30m (100ft) sensing range. The sensor features Bipolar - one current sourcing (PNP) and one current sinking (NPN) open-collector transistor output configurations. 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).

• Switch-selectable for light operate or dark operate
• 1 millisecond Response
• Highly repeatable
• Both sourcing and sinking outputs (150mA maximum each)
• Rugged, epoxy-encapsulated construction
• Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12 and 13, IEC IP67
• Physically and electrically interchangeable with 18mm barrel-type photoelectrics
