Sick deTec4 Prime safety light curtain is extra-ruggedA tough addition to Sick's flagship safety light curtain family, the deTec4 Prime is an extra-rugged, high-performance light curtain that is easy to install and use. It is also suitable for harsh environments and exceptionally wide machines. You can see how tough the deTec4 Prime in this short video.

With the Sick deTec4 Prime, it is said to be easier than ever to achieve hazardous and access point safety protection up to PLe/SIL3. The deTec4 Prime is expected to find applications in machine tool protection where its range can protect a long piece of equipment such as a deep boring drill, or a group of linked multi-function machine tools.

With integrated laser alignment for simple installation, the Sick deTec4 Prime provides full end-to-end protection with no blind zones and a wide scanning range of up to 21m. It complements the highly successful deTec4 Core safety light curtain that is said to have set new protection performance standards since its launch in 2013.

With integral dip switches for simple in situ configuration, the deTec4 Prime is quick and easy to commission without the need for a computer. Cascading up to three deTec4 Prime safety light curtains minimises wiring complexity and reduces the number of safety inputs in the control cabinet. The coded light beam option prevents optical interference between devices in side-by-side applications.

Dr Martin Kidman, Sick UK Safety Specialist, says: "With the deTec4 Prime, Sick has produced yet another functional safety device optimised for maximum uptime through ease of connectivity and quick commissioning whilst meeting the most stringent international safety standards.

"Launching the deTec4 Prime enhances our portfolio of next-generation light curtains, ready for use in the Industry 4.0 Smart Factory. Through the space-saving, robust design of the Sick deTec4 Prime, machine integration is optimised in order to achieve higher operator productivity."


The Sick deTec4 Prime offers protective field heights in increments from 300mm to 2100mm and a choice of finger (14mm) or hand (30mm) resolution providing protection against operator intervention in accordance with EN ISO 13855 (Safety of machinery. Positioning of safeguards with respect to the approach speeds of parts of the human body) in applications covering up to 21m. It is a type 4 device (IEC 61496), enabling compliance in applications with requirements up to PLe (EN ISO 13849) and SIL 3 (IEC 61508).

Configuration and range adjustment is automatic, requiring no additional set-up; diagnostics indication is simple and additional functions such as EDM monitoring or manual reset are activated automatically by connection.

A combination of the innovative mounting bracket configuration, semi-circular contours and alignment LEDs facilitate the installation process, meaning the Sick deTec4 Prime can be installed quickly and easily in seconds. LEDs along both sender and receiver indicate the field, OSSD status and the state of the light curtains for efficient maintenance and diagnostics. The deTec4 Prime also enables a reset button to be connected and/or a facility for monitoring external devices (EDM), which can reduce wiring and the need for additional devices in the control cabinet, tereby saving space.

The Sick deTec4 Prime benefits from a tough, IP65 or IP67, impact- and warp-resistant enclosure with an operating temperature range from -30 to +55degC for reliable operation in harsh conditions and a variety of demanding industrial environments.
