2 Safety instructions

- The unit described is a subcomponent for integration into a system.

• The system architect is responsible for the safety of the system.

• The system architect undertakes to perform a risk assessment and to create documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. This documentation must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the architect of the system.

• Read this document before setting up the product and keep it during the entire service life.

• The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
• Only use the product for its intended purpose (→ Intended use).
• If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.
• The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator.
• Installation, electrical connection, set-up, operation and maintenance of the product must be carried out by qualified personnel authorised by the machine operator.
• Protect units and cables against damage.

3 Intended use

The device detects metal without contact and outputs the distance value in micrometres ( µ m) via IO-Link.

4 Function

The PCB coil and the capacitor form an LC resonant circuit, also known as a basic sensor.

If a target is brought into the sensor field, the inductance changes. The change in inductance is analysed by the external electronics, and a process value is output depending on the distance. Since there is no ferrite core, the devices are insensitive to interference from strong magnetic fields. To equalise material properties and target sizes as well as the installation situation, the device offers two options for an application configuration ( → Application configuration ☐ 12).

The device achieves the accuracies specified in the data sheet after a warm-up time of 15 minutes.

2: Housing
3: External electronics
4: Capacitor
5: Coil
6: Alternating electromagnetic field = active zone
7: Target = electrically conductive material
8: Ideal direction of movement of the target

4.1 Switching function with switch point

A switching signal can be provided for process value monitoring. OUT1 will change its switching status according to the parameter settings as a function of the distance to the object.

You can choose between the following switch point modes according to the IO-Link smart sensor profile:

• Single point mode
• Two point mode
• Window mode

Term	Explanation
H	Hysteresis, can be set via the parameter [HY]
High active	Switch-point logic:switching output is switched on object detection = NO (normally open)
Low active	Switch-point logic:switching output is not switched on object detection = NC (normally closed)
PDV (Process data variable)	Process data value
SP	Switch point (SP1 must be greater than SP2)
SSC (Switching Signal Channel)	Switching signal channel
SSC1	Switching signal channel 1
SSC2	Switching signal channel 2
Single point mode	Single switch point mode
Two point mode	Two switch point mode
Window mode	Window mode

Tab. 1: definition of terms

Single point mode

Only one switch point (SP1) is manually set or taught. The switch-off point results from the switch point and the set hysteresis (H).

Single point mode – low active
SP1+H: switch-on point
SP1: switch-off point

Single point mode – high active
SP1: switch-on point
SP1+H: switch-off point

Two point mode

A switch point (SP1) and a switch-off point (SP2) are manually set or taught.

Two point mode – low active
SP2: switch-off point
SP1: switch-on point

Two point mode – high active
SP1: switch-off point
SP2: switch-on point

Window mode

Two switch points (SP1) and (SP2) are manually set or taught. The two switch points delimit a window area.

Window mode – low active

• The output switches off (low active) within the switching limits SP1 and SP2.
• The output switches on (high active) when the process value leaves the window area and the set hysteresis is exceeded: SP1+H or SP2-H.

Window mode – high active

• The output switches on (high active) within the switching limits SP1 and SP2.
• The output switches off (low active) when the process value leaves the window area and the set hysteresis is exceeded: SP1+H or SP2-H.

Conditions for switching points:

• SP1, SP2 between 2xMBA and MBE -3%
- SP1+H, SP2+H < MBE
• H between 3...15%

Diagnostic IO-Link data:

• Upper limit MBE +5 µ m
• Lower limit MBE -5 µ m

Glossary

Aktive Schaltzone / Aktive Zone

Area above the sensing face in which the sensor reacts to the approach of the target.

Ausgangsfunktion

Normally open: Object within the active zone - output stage supplied with current. Normally closed: Object within the active zone - output stage not supplied with current. Programmable: Choice between normally closed or normally open. Positive switching: Positive output signal (to L-). Negative switching: Negative output signal (to L+).

Current consumption

The current for self-supply of DC appliances without load.

Hysteresis

Difference between switch-on and switch-off point.

Operating voltage

Voltage range in which the sensor operates reliably. A stabilised and smoothed direct voltage should be used! Take into account the residual ripple.

Product standard

IEC 60947-5-2

Standard target

Square-shaped steel plate (e.g. S235JR) of a thickness of 1 mm with a side length equal to the diameter of the sensing face or 3 x Sn, depending on which value is the highest.

Switch point drift

The shifting of the switch point due to changes in the ambient temperature.

Switching frequency
