DIN EN 60068-2-38/IEC 68-2-38: test Z/AD
Up to 2 000 m (6 600 ft) above sea level
a = 300 m/s² = 30 g, 3 planes x 2 directions x 3 shocks x 18 ms,
as per test Ea, prEN 60068-2-27:2007
a(RMS) = 50 m/s², ASD = 1.25 (m/s²)²/Hz, f = 5 to 2000 Hz, t = 3 x 2 h,
as per test Fh, EN 60068-2-64:2008
2-wire AC/DC
• AC mode: the device has reverse polarity protection.
• DC mode: in the event of reverse polarity the maximum safety mode is always
detected. Check the wiring and perform a function check before commissioning.
The device is not damaged in the event of reverse polarity.
3-wire DC-PNP
Integrated. In the event of reverse polarity, the device is deactivated automatically.
2-wire AC/DC
During switching the sensor checks whether a load, e.g. relay or contactor, is
present (load check). If an error occurs, the sensor is not damaged.
Smart monitoring: normal operation is resumed once the error is fixed.
3-wire DC-PNP
Overload protection/short-circuit protection at I > 250 mA; the sensor is not
destroyed.
Smart monitoring: check for overload in intervals of approx. 1.5 s; normal
operation is resumed once the overload/short-circuit is fixed.
• IP65/67 NEMA Type 4X Enclosure (M12 connector)
• IP65 NEMA Type 4X Enclosure (valve plug)
• IP66/68 NEMA Type 4X/6P Enclosure (cable)
Electromagnetic compatibility in accordance with all relevant requirements of the
EN 61326 series and NAMUR recommendation EMC (NE21). For details, refer to
the EC Declaration of Conformity.
