Banner Engineering SM31EQD Infrared Opposed Mode Sensor

The SM31EQD is a compact, sealed opposed-mode infrared sensor housed in reinforced thermoplastic polyester with acrylic lenses and stainless steel screws. It features a self-contained design, designed for reliable operation in industrial applications, with switch-selectable light or dark operate modes. The sensor supports 10 to 30V DC power supply, offers high repeatability with a 1ms response time, and is protected against reverse polarity, transient voltages, overloads, and short circuits. It is physically and electrically compatible with 18mm barrel-type photoelectric sensors and operates within a temperature range of -20°C to 70°C. Typical applications include sensing, instrumentation, and medical equipment.
