SICK i110-SA223 i110S Safety Switch
Description
i110-SA223 is a SICK i110S safety sensor (part no. 6025074) that monitors the position of a guard door or flap and gives a safe release signal only while the guard is closed. The catalogue summary lists: system part: sensor; positive action N/C contacts: 2; N/O contacts: 2; housing material: Metal; connection type Detail: Cable gland, 1 x M20.
How the i110-SA223 works and where it fits
On a machine, the safety switch is only one element of the safety function. Series connection of several switches saves wiring on machines with many doors, but diagnostic coverage and the achievable performance level depend on how the chain is wired and on the number of devices.
Tampering is the main reason ISO 14119 asks for coded actuators: a device with a high coding level cannot be bridged with a spare actuator found on site. Door play affects the switching distance in real life; a door that moves a few millimetres in its frame can pass a gap that the data sheet marks as the safe switching distance.

Ordering i110-SA223: type code, part number and fit
Wiring data to note: connection: cable gland, 1 x M20; current: 3 A (240 V AC); 2 A (24 V DC).
Housing and environmental limits listed: storage temperature –20 °C … +80 °C; operating temperature –20 °C … +80 °C; enclosure rating IP67 (IEC 60529); weight 0.54 kg.
For installation, mount sensor and actuator rigidly on the frame and the door so the door cannot move beyond the switching distance, and keep to the mounting orientation in the data sheet.
Draw the safety circuit before ordering: which relay or safe input evaluates the signal and how the reset works are part of the function.

About brand
SICK is the German maker of industrial sensors: photoelectric and proximity sensors, safety laser scanners and light curtains, encoders, distance sensors, code readers and gas analysers. Erwin Sick, an optics engineer, founded it in Munich in 1946, and in 1952 it introduced its first marketable accident-prevention light curtain, which protected press operators by stopping the machine when a hand broke the light beam. The company moved to Waldkirch in the Black Forest in 1956 and is still headquartered there. It is a privately held company, and has been an Aktiengesellschaft (AG) since 1996.

Choosing a SICK sensor
For object detection, the sensing principle comes first. A retro-reflective sensor (WL series) sends light to a reflector and switches when an object breaks the beam; it is reliable over long distances and easy to align. A sensor with background suppression (WTB series) detects an object at a set distance and ignores what is behind it, which suits conveyors with shiny or dark backgrounds. A through-beam pair (WS/WE) gives the longest range and the highest reliability in dust. For transparent bottles and film, use a model built for transparent objects (for example WL12G-3B or WL150-P420). The digits in the code also matter: "P" usually means a PNP output and "N" NPN, and the last digits set the connector or cable. For machine guarding, a safety laser scanner such as nanoScan3 or microScan3 protects an area, while a safety controller such as Flexi Soft combines several safety devices.
Where SICK products are used
In Oman and the GCC, SICK sensors are used in packaging and bottling lines, food and beverage plants, logistics and airport baggage handling, cement and steel plants, ports and cranes, automated warehouses, and on machines built by European OEMs. SICK safety scanners guard robots and automated guided vehicles, and its encoders give position feedback on motors, hoists and conveyors.

Ordering SICK products: what we need
Send the type code and the 7-digit SICK part number from the label (for example WTB12-3P2431 together with its part number). For a replacement sensor, add the output (PNP or NPN), connection (M8, M12 or cable) and sensing distance. For encoders, add the interface (incremental, SSI, PROFIBUS, PROFINET), resolution and shaft type. For safety scanners, tell us the model and whether the existing configuration needs to be kept.
