Environmental influences exceeding the limits specified in the technical data sheet may impair the function of the device. This applies in particular to applications in hazardous areas and with adverse environmental influence such as pressure, chemicals, temperature fluctuations, moisture and radiation as well as mechanical stress, especially if the products are not installed properly.

It is the customer's responsibility to ensure that the products are suitable for the intended application. Using the products in applications where the safety of people depends on the function of the product is not permitted. If these instructions are not adhered to, death or severe injury may occur.

Unless otherwise specified in the data sheet, the products are designed for operation at altitudes up to 2,000 m above sea level.

Products with protection class II must be regularly checked for damage.

4 Electrical connection

The device must be connected by a qualified electrician.

▶ Observe the national and international regulations for the installation of electrical equipment.
▶ Geräte mit Schutzklasse III ausschließlich nach SELV / PELV mit Spannung versorgen.

▶ Disconnect power.
▶ Gerät nach Angaben auf dem Datenblatt/Typenschild anschließen.

4.1 Connection systems

Sensors must not be operated in parallel connection (OR)!

Series connection (AND) is not recommended since the power-on delay times, voltage drops and current consumption add up. U_{B\ min} (sensor) and U_{HIGH\ min} (load) must remain unchanged.

5 Glossary

Term	Explanation
Active zone	Area in which the device reacts to the approach of the target.

Term	Explanation
Output function	Normally open: Object within the active zone > output switched. Normally closed: Object within the active zone > output blocked. Programmable: Choice between normally closed and normally open. Positive switching: positive output signal (to L-). Negative switching: negative output signal (to L+).
Switch-off delay	Time delay between the target leaving the active zone of the device and the switching of the output stage, determined using a mechanical measurement method.
Rated frequency of the supply network	50 Hz, 60 Hz or direct voltage
Rated insulation voltage	AC and DC devices with protection class II: 250 V ACDC devices with protection class III: 60 V DC
Rated short-circuit current	For short-circuit-proof devices: 100 A. For AC devices without short-circuit protection: Required fuse ➕ Data sheet.
Rated impulse withstand voltage	AC devices depending on UB: 140 V AC = 2.5 kV or 250 V AC = 4 kV( ≈ overvoltage category III). DC devices with protection class II: 4 kV ( ≈ overvoltage category III). DC devices with protection class III: 60 V DC: 0.8 kV ( ≈ overvoltage category II).
Power-on delay time	The time the device needs to be ready for operation after application of the operating voltage.
Operating voltage► Start-up behaviour	Voltage range in which the device operates reliably. A stabilised and smoothed direct voltage should be used. Once the operating voltage has reached its minimum value for the first time, the final operating voltage should be reached within one second at the latest. Start-up should be continuous and monotonic.
Blind zone	Zone between the sensing face and the minimum distance within which objects cannot be detected.
Switch-on delay	Time delay between the target entering the active zone of the device and the switching of the output stage, determined using a mechanical measurement method.
Recommended direction of approach	The objects to be detected should move laterally into the active zone. The distance between the sensing face and the object should be approximately equal to half the operating distance.
Utilisation category	AC devices: AC-140 (control of small electromagnetic loads with holding currents < 200 mA). DC devices: DC-13 (control of solenoids).
Hysteresis	Difference between switch-on and switch-off point.
Short-circuit protection	Pulsed short-circuit for short-circuit-proof devices. If applicable, observe the fuse specifications given in the datasheet. In devices with pulsed short-circuit, the short-circuit protection may activate in the case of incandescent lamps, electronic relays, capacitive loads or low-resistance loads.
No-load current	Current consumption without load current for the internal supply of 3-wire devices.
Measuring range	Distance range in which the process value changes. The final value of the measuring range is the maximum value that the measured value can reach.
Minimum operating current Minimum load current	Smallest operating current required for maintaining conductivity of the switching element in 2-wire devices.

Leakage current	Current for the internal supply of 2-wire devices, also flows through the load when the output is blocked.
Switch point drift	Change in the operating distance as a function of the ambient temperature specified in the data sheet.
Protection rating	IPxy according to IEC 60529IP68 test condition: 1 m water depth for 7 daysIPx9K according to ISO 20653
Voltage drop	Voltage at the output switching element in the conductive state.

Transport and storage temperature Ambient temperature	The transport and storage temperature corresponds to the ambient temperature specified in the data sheet.► With cable devices, do not move the cable below -25 °C.
Ultrasonic reflector for UGR version	The functional specifications refer to a mild steel reflector defined by ifm at maximum range with an edge length of 200 mm (UGT) or 400 mm (UIT). Besides mild steel reflectors, objects that can reflect sound well can also be used as a reflector. The min. reflector size depends on the object size and the angle of aperture of the emitted sound.
Pollution degree	The products are designed for pollution degree 3 according to IEC 60947-1.
Maintenance, repair and disposal	When used correctly and in accordance with the intended use, no further maintenance and repair measures are necessary. ➕ 1► After use dispose of the device in an environmentally friendly way in accordance with the applicable national regulations.
Repeatability	Unless otherwise specified in the data sheet, the difference between any two measurements within the measuring range must not exceed 10 %.
