SICK STR1-SAMF03P5 STR1 Safety Switch
Description
STR1-SAMF03P5, part no. 1073218, is a SICK STR1 device for guard-door interlocking and monitoring on machines and process equipment. The catalogue summary lists: actuator design: Mini; coding: Permanently coded; assured switch on distance Sao: 14 mm; connection type Detail: Cable, 5-wire; length of cable: 3 m.
What the STR1-SAMF03P5 does in a machine
Coded sensors and tongue or lever actuators address the second need in different ways: a coded actuator cannot be replaced by a loose piece of metal, while a mechanical actuator needs a positive mechanical action to operate the contacts. The coding level, where the data sheet prints one, tells you how strongly the device resists manipulation under ISO 14119.
Read the section on series connection in the operating instructions before wiring more than a few guards. 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.

For the mounting location, note operating temperature –30 °C … +70 °C; weight 150 g; dimensions 40 mm x 18 mm x 26 mm; storage temperature –30 °C … +70 °C; enclosure rating IP67 (IEC 60529); IP69K (ISO 20653); housing VISTAL®; vibration 10 Hz … 55 Hz, 1 mm (IEC 60068-2-6); shock 30 g, 11 ms (IEC 60068-2-27).
Typical uses are guard doors on packaging lines, robot cells, conveyors and gearbox covers.
Check enclosure rating, housing material and temperature range in the table for wash-down or dusty areas, and decide whether a locking version is needed where the hazard continues after the stop command.

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.
SICK company profile

|---|---|
| Headquarters | Waldkirch, Baden-Württemberg, Germany (since 1956) |
| Ownership | Privately held; after the founder's death in 1988 his widow Gisela Sick became the main shareholder. Legal form SICK AG since 1996 |
| Size | More than 12,000 employees and group revenue of about EUR 2.3 billion (company figures for 2023) |
| First breakthrough | Accident-prevention light curtain for presses, shown in Hanover in 1952 |
| International growth | First foreign subsidiary in France in 1972, United States in 1976; today sales and service companies worldwide |

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.
