Pilz PSENini inductive safety sensors

Pilz PSENini inductive safety switches detect the approach of metallic objects without contact and supply the necessary safe signals for position and end limits. PSENini can also be used to generate pulses for counting tasks or for detecting rotational movements without the need for uniquely coded actuators. It is space-saving, reacts to metals and is easily integrated into the machine.

Multiple versions provide flexibility for application integration: the cube-shaped proximity switch with a plastic housing detects objects within a 15 mm operating distance, and with protection class IP68/IP69, the three cylindrical models with stainless steel housings allow for operating distances of 2–10 mm and are also appropriate for more hygiene-critical applications. The operating temperature range of the sensors is -25 to +70°C.

Inductive safety sensors are used in a broad range of industries, such as in packaging plants, food and beverage, and toolmaking sectors. The standardised OSSD safety outputs on the inductive safety switches make integration simple and enable a direct connection to the appropriate safety controller, such as PNOZmulti, myPNOZ or PSS4000.

The sensors have no blind range, so no minimum distance is required between sensor and object, and they can be used in safety applications up to PL d, Cat. 2 (EN ISO 13849-1) or SIL 2 (IEC 62061). Redundant use enables up to PL e, Cat. 3/SIL 3.
