| Product Number | BE-A201 |
| Part Number | BE-A201 |
| Detectable air gap | 0.8 mm 0.032 in or more (Note) Sensing air gap refers to the width of an air bubble formed in the entire area of the inner diameter of the tube. Please note that this product cannot sense very small air bubbles or water drops. |
| Sensing object | Liquid (Note) Sensing is affected by dirt or residues adhered to the inner wall of the tube. Please maintain the tube regularly. |
| Applicable tube dia. (OD×ID) | ø2 mm × ø1 mm ø0.078 in × ø0.039 in (Note) When using a tube out of specifications or it doesn’t have a smooth surface, please test sensing on the actual machine before use. |
| Applicable tube type | Transparent resin tube (equivalent to PFA) (Note) When using a tube out of specifications or it doesn’t have a smooth surface, please test sensing on the actual machine before use. |
| Supply voltage | 5 to 24 V DC ±10 % Ripple P-P 10 % or less |
| Current consumption | 15 mA or less |
| Output (Incorporated with 2 outputs) | NPN open-collector transistor •Maximum sink current: 50 mA •Applied voltage: 30 V DC or less (between output and 0 V) •Residual voltage: 2 V or less (sink current at 50 mA) 1 V or less (sink current at 16 mA) |
| Output (Incorporated with 2 outputs):Output operation | Switchable either Liquid-absent-ON or Liquid-present-ON |
| Output (Incorporated with 2 outputs):Short-circuit protection | Incorporated |
| Response time:When detecting bubble | 30 μs or less (Note) Actual response time may differ from specification (typical example using applicable tube) due to dimension, light transmission or surface state of test tube in use. |
| Response time:When detecting liquid | 80 μs or less (Note) Actual response time may differ from specification (typical example using applicable tube) due to dimension, light transmission or surface state of test tube in use. |
| Operation indicator | Orange LED (lights up with absent liquid) |
| Protection circuits | Power supply reverse polarity protection , Output reverse polarity protection |
