Parameter Table

Instructions

1. Supply Voltage:

   • The A1212S-1WR3 should be powered with a supply voltage (Vcc) between 4.5V and 5.5V. Ensure that the power supply is stable to avoid any damage to the sensor.

2. Output Configuration:

   • The output type is open collector. Connect a pull-up resistor between the output pin and the supply voltage (Vcc) to ensure proper operation. The typical value for the pull-up resistor is around 1kΩ to 10kΩ.

3. Load Connection:

   • The maximum output current (Iout) is 50mA. Ensure that the load connected to the output does not exceed this limit. For higher current applications, consider using a transistor or relay to drive the load.

4. Mounting:

   • Mount the sensor in a position where the target object can be detected within the rated sensing distance (Sr). The hysteresis (Hys) ensures stable operation by preventing rapid switching when the target is near the detection threshold.

5. Environmental Conditions:

   • The operating temperature range is from -40°C to 85°C. Ensure that the sensor is not exposed to temperatures outside this range to prevent damage or malfunction.
   • The storage temperature range is from -40°C to 125°C. Store the sensor in a dry and cool place when not in use.

6. Response Time:

   • The response time (Tr) is typically between 0.5ms and 2.0ms. This means the sensor will detect changes in the presence of the target object within this time frame.

7. Handling:

   • Handle the sensor with care to avoid physical damage. Avoid exposing the sensor to excessive mechanical stress or chemical substances that could degrade its performance.

By following these parameters and instructions, you can ensure optimal performance and longevity of the A1212S-1WR3 sensor.
