SICK IN4000 Series Inductive Non-Contact Safety Switch Stainless Steel Housing 24V DC 4A 3 NO Contacts M12 Connector

SICK IN40-D0303K Inductive Non-Contact Safety Switch from the IN4000 series is engineered for reliable and safe machine-guard monitoring in demanding industrial applications. This device features a robust cylindrical stainless steel housing that withstands harsh conditions, including washdown environments thanks to its IP67 and IP69K ratings. Operating on a 24V DC supply with a typical current draw of 15 mA, it delivers a contactless safety function via a semiconductor pulsed output along with visual status indicators for operational clarity.

The switch offers three normally open safety contacts and is designed with a 15 mm assured switch-off distance, providing secure separation to enhance operator safety. It integrates an M12 4-pin plug connection with a stainless steel coupling nut and a metal actuator type, ensuring durable connectivity and resistance to mechanical wear. The device conforms to SIL3 safety integrity and is rated for PL e Category 3 safety performance, making it suitable for high-risk applications.

Engineered to operate in temperature ranges from -25°C to +70°C, it also withstands vibration and shock up to 30g, fulfilling rigorous industrial safety standards including ACMA, cULus, EC-Type, IEC, and RoHS certifications. This safety switch is especially pertinent for machine-guard monitoring on production lines and in food industry areas requiring IP69K washdown suitability. It is compatible with safety controllers needing pulsed semiconductor outputs and ideal for guard interlocking in uncoded actuation scenarios.

While the actuator is not included, the switch's stainless steel housing and advanced safety features offer dependable performance in safety interlock applications. The device is built for a long mission time, specified up to 10 years under standard conditions and up to 20 years under controlled environments.

Operates with 24V DC voltage supply and 4A switching current. Three normally open safety contacts configured for safe output. Cylindrical stainless steel housing with black color finish offers durability and corrosion resistance.

M12 plug type connection ensures quick and secure installation. Safety category 4 compliance and multiple international approvals ensure reliability. Assured switching distance of 15 mm provides reliable safety separation.

IP67 and IP69K ratings make it suitable for harsh and washdown environments. Visual status indicators allow clear operational feedback. Designed to withstand wide temperature and shock/vibration ranges for industrial robustness.
