| Notes | 1. NPN < 200 μA for load impedance > 3 KΩ; for load current of 100 mA, leakage < 1% of load current
2. When mounting the M25U, care should be taken to acoustically isolate the emitter and receiver to eliminate sound energy coupling between the sensor pair. This is best accomplished with elastomeric materials between the sensor and rigid mounting brackets.
