SICK UE410-XU3T50 Flexi Classic Safety Relay
Description
UE410-XU3T50 (part no. 6032471) is part of the SICK Flexi Classic range of compact safety evaluation devices. The catalogue summary lists: module: I/O module; specialization: Universal; inputs: 4 safety inputs, 4 switching inputs; number of muting sensors: 0 / 2; outputs: 4 safety outputs, 2 test outputs.
Understanding the UE410-XU3T50 before you specify it
Which relay is right depends on the sensor on its input. Potential-free contacts, OSSD semiconductor outputs from light curtains and scanners, and two-hand controls each need a matching input circuit; connecting the wrong type can give a false sense of safety.
Manual reset and automatic reset behave differently after a stop; an unintended restart is prevented only if the reset is wired and configured as the risk assessment requires. The achievable performance level is the result of the whole chain, relay, sensors, wiring and contactors, and not of the relay alone.

Ordering UE410-XU3T50: type code, part number and fit
For the control cabinet and the cable run, the relevant figures are connection is plug-in screw-type terminals; supply is 24 V DC (19.2 V DC … 30 V DC); power draw is ≤ 3 W (DC).
For the mounting location, note storage temperature of –25 °C … +70 °C; dimensions of 22.5 mm x 96.5 mm x 120.8 mm; weight of 180 g; vibration of 5 g RMS, 5 Hz … 500 Hz (EN 60068-2-64); operating temperature of –25 °C … +55 °C; enclosure rating of IP40 (EN 60529).
Before ordering, confirm the input type against your sensor, the number of safe outputs and their switching capacity against your contactors, the supply voltage and whether the unit needs screw or spring terminals.
Leave room in the panel layout for DIN-rail clearance and the heat of neighbouring modules.

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.
