Warning— Each electrical rating is an individual maximum and cannot be exceeded!

1

Configuration with actuator away from the switch

2

Proximity of ferrous materials usually reduces sense range — typically by 50%. The shape and type of material cause a wide diversity of effects.

Testing is required to determine actual sense range for specific applications.

3

Can withstand inrush surge up to 4 amps. Voltage drop is 1.5V, minimum switch current, 30 mA, triac output.

4

Do not exceed 10 switches in series.
