User manual for Azbil FL2B series DC 2-wire proximity sensors, covering specifications, installation, wiring, and usage precautions.
This document is the user manual for the Azbil FL2B series proximity sensors, specifically models FL2B-2□6(-F) and FL2B-4□6(-F). It provides essential information for the correct and safe use of the product, including specifications, installation precautions, and wiring methods. The manual also details usage restrictions and environmental factors that may affect the sensor's performance.
Key sections include guidelines on mutual interference when sensors are installed in parallel or facing each other, warnings against shaking the cable, and specific instructions for series and parallel connections. It outlines the electrical specifications such as power supply voltage, current consumption, and operating temperature range, along with physical dimensions for both model variants. This manual is written in Chinese.
| Detection Distance | 2±0.4mm (FL2B-2□6(-F)), 4±0.4mm (FL2B-4□6(-F)) |
|---|---|
| Set Distance | 0～1.4mm (FL2B-2□6(-F)), 0～2.8mm (FL2B-4□6(-F)) |
| Power Supply Voltage | 10～30VDC |
| Current Consumption | 0.8mA or less |
| Load Current | 3～100mA |
| Residual Voltage | 3V or less |
| Operating Temperature Range | -25～+70℃ |
Series connection is not recommended because it can cause erroneous output. If series use is necessary, parallel a 10kΩ resistor with each sensor.
The cable can be extended up to 100m using a wire with a cross-section of 0.3mm² or more.
No, the sensor should not be placed or used outdoors.
The residual voltage on FL2B is 3V, so it cannot drive a 12VDC relay.
