Sensors CLS 23 are equipped with protection against over-voltages and current overload. The capacity

loads and low resistance (bulb) are evaluated by sensors with output type P and S as short circuit.

Sensors with output type R are designed for interconnect to intrinsically safe supply units.

In case of strong ambient electromagnetic interference, paralleling of conductors with power distribu-

tion, or for the distribution to distance over 30 m, we recommend to use shielded cable.
