MA Motion Sensor (AMA1, AMB1, 2, 3)

2. External triggering type

HOW TO USE

• Wiring diagram of connector

Notes: 1. The output transistor has an open collector structure.

• Detection status: Output transistor ON (connected to GND)

• Non-detection status: Output transistor OFF (open state)

2. The status of the external trigger input is as follows:

• Open at the high level

• GND (less than 0.8V) at the low level

Under no circumstances must a high-level voltage be applied.

3. To maintain the power supply noise performance, be certain to connect a capacitor (33µF or more) to the sensor power supply input terminal in order to stabilize

the power supply voltage.

Built-in oscillation circuit type External triggering type

NPN output type

PNP output 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.

Note: The sensor recognizes at the V

TH → VTL edge of an external trigger that the

external trigger has been input.
