SICK C4MT-09614ABB03FB0 miniTwin Safety Light Curtain
Description
C4MT-09614ABB03FB0 is a SICK miniTwin electro-sensitive protective device (part no. 1206965) that guards a hazardous opening with an invisible curtain of light instead of a fixed fence. The catalogue summary lists: usage: miniTwin4 as a standalone device; mounting system type: O-fix bracket; safety level: PL e, SIL 3, Type 4; resolution: 14 mm; scanning range: 5 m.
C4MT-09614ABB03FB0: function, principle and typical use
Resolution therefore decides what the device protects: fine resolutions guard fingers and hands at short distances, coarser ones guard the body at a greater distance. The protective field height, the resolution and the response time together set the minimum safety distance from the curtain to the hazard, which is calculated to ISO 13855 / EN 999 by the machine builder.
Because the beams are invisible near-infrared, operators see nothing, so the housing carries LEDs that show state and alignment. A periodic test with a test rod across the protective field confirms that an object of the specified size is actually detected before each shift or at the interval your procedure sets.

Selection and installation notes for C4MT-09614ABB03FB0
Worked example, derived and not a design value: with the listed response time of 17 ms, the device contributes 2 x 17 = 34 mm to the safety distance (approach speed 2,000 mm/s), and the penetration allowance for a 14 mm resolution is 8 x (14 – 14) = 0 mm, so at least 34 mm plus the distance travelled during your machine stopping time must separate the curtain from the hazard. Your own calculation to ISO 13855 governs.
Supply and signal data as listed: resolution 14 mm; connection plug, M12, 5-pin; power draw ≤ 3 A; response time ≤ 17 ms; range 0 m … 4 m; supply 24 V DC (19.2 V DC … 28.8 V DC); outputs PNP semiconductors, short-circuit protected, cross-circuit monitored.
Fitting and site conditions are covered by these entries: operating temperature: –20 °C … +55 °C; shock: 15 g / 6 ms (EN 60068-2-27); weight: 340 g; storage temperature: –25 °C … +70 °C; housing: aluminum alloy ALMGSI 0.5; enclosure rating: IP65 (EN 60529); wavelength: 850 nm; vibration: 5 … 150 Hz, 3,5 mm / 1 g (EN 60068-2-6).
Check the enclosure rating and temperature range in the table against the actual location, and mount the curtain so that it cannot be bypassed by reaching over, under or around it.
Hold the machine’s overrun time in mind: the curtain stops the signal, but the hazard stops only after the machine’s own stopping time, and this total is what the safety distance is based on.

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.
