MA Motion Sensor (AMA1, AMB1, 2, 3)
TIMING CHART
1. Built-in oscillation circuit type
Notes: 1. Circuit stability time : Max. 12 ms
2. During the time taken for the circuit to stabilize after the power is turned on, the ON/OFF status of the output transistor is not determined by whether the sensor is
in the detection status or non-detection status.
2) External triggering type (trigger conditions: trigger pulse width = 20µs and trigger synchronization = 5ms)

Notes: 1. The thin short type is only available for 5V DC.
2. The ratio between the 4 operating modes (*a to *d) depends on the
external trigger period and detector time, and the current consumption
corresponds with this varying ratio.
3. A high level is established in the open state due to pull-up by the internal
circuit. (Refer to the connector wiring diagram.)
4. The output transistor is open collector.
The output transistor is turned ON by the sensor detection status and
turned OFF by its non-detection status.
