3 / 3 page Installation MINI-BEAM® dc-Voltage Series 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. Certifications Specifications |
