What Is a Machine Guard Safety Switch?
A machine guard safety switch is used to monitor whether a movable protective guard, door, cover, or access point is in the required position.
In industrial automation systems, access to hazardous areas may need to be monitored before certain machine operations are allowed. A safety switch can provide a switching signal to the connected safety-related control logic.
The SICK i110-RA223 6025108 is designed for this type of application. Its positive-opening normally closed contacts are particularly relevant to safety-related guard monitoring.
Typical applications can include:
-
Machine safety doors
-
Protective covers
-
Industrial machine guards
-
Production machinery
-
Packaging machines
-
Material handling equipment
-
Automated production lines
-
Industrial manufacturing equipment
Key Features of the SICK i110-RA223
1. Two Positive-Opening Normally Closed Contacts
The i110-RA223 provides two positive-opening N/C contacts together with two N/O contacts. This contact configuration can be integrated into appropriate machine safety circuits according to the system design.
For replacement buyers, checking the contact configuration is important because a visually similar safety switch may not have the same electrical configuration.
2. Four Actuation Directions
The SICK datasheet specifies four actuation directions for the i110-RA223.
This provides flexibility when installing the safety switch on machinery with different guard and actuator arrangements.
3. Turning Lever Actuator
The i110-RA223 uses a turning lever actuator design. This makes it suitable for machine guarding applications where the mechanical movement of a guard needs to operate the switch.
When replacing an existing safety switch, buyers should verify the actuator design, mounting arrangement, contact configuration, and mechanical operating direction before ordering.
4. M20 Cable Entry
The model uses one M20 cable entry, with a conductor cross section of up to 2.5 mm² according to the SICK datasheet.
This is an important specification to check when replacing a safety switch because cable entry and wiring requirements can affect installation compatibility.
Electrical Specifications
The SICK i110-RA223 uses a slow-action switching element and is specified for AC-15/DC-13 utilization categories.
Its rated operating current is 3 A at 240 V AC and 3 A at 24 V DC, while the rated insulation voltage is 250 V.
For machine safety projects, the electrical characteristics should always be evaluated together with the complete safety circuit, connected safety logic, load, and applicable machine safety requirements.
Safety-Related Parameters
The SICK datasheet specifies a B10d value of 2 × 10⁶ switching cycles under low load and identifies the switch as Type 1 according to EN ISO 14119. The actuator coding level is listed as uncoded.
An important point for engineers is that the switch itself does not provide internal fault detection. SICK states that fault detection is performed by the connected safety-related logic unit.
Therefore, the i110-RA223 should not be evaluated as an isolated component. Its suitability depends on the complete machine safety architecture and the applicable safety requirements.
SICK i110-RA223 Applications
Industrial Machinery
Machine builders can use electromechanical safety switches to monitor access doors and movable guards on industrial machinery.
Automated Production Lines
Production lines may contain multiple guarded areas. A safety switch can provide guard-position information to the relevant safety control system.
Packaging Equipment
Packaging machinery often contains moving mechanisms and guarded access areas. Safety switches can be used as part of the machine's protective system.
Material Handling Systems
Conveyors and automated material-handling equipment may use safety switches on access doors, covers, or guarded sections.
Machine Replacement and Maintenance
For maintenance teams, identifying the exact part number is essential when replacing an installed safety component.
The combination SICK i110-RA223 + 6025108 is particularly useful as a search reference because both the model number and part number can be used to identify the required component.
How to Replace a SICK 6025108 Safety Switch
