Siemens 3SE5 Safety Hinge Switch 1 NO/2 NC Metal Housing IP65 230V AC/DC, 6A Contact Current 3SE5212-0LU21

Siemens 3SE5212-0LU21 Safety Hinge Switch 1 NO/2 NC is an industrial-grade Safety Interlock Switch designed for monitoring protective hinged doors and flaps. It features a robust metal housing and an IP65 rating, making it suitable for harsh industrial and automation environments where durable protection and reliable operation are critical.

The 3SE5 series hinge switch utilizes a positive pivoting point connection between the switch and door hinge to prevent tampering and ensure precise mechanical monitoring. It supports safety levels up to Category 4 according to EN 954-1 and SIL 3 as per IEC 62061 standards. The switch provides simultaneous shutdown and signaling via its snap-action contacts, ensuring effective machine safety.

Key technical specifications include contact configuration of one normally open (NO) and two normally closed (NC) contacts, compatibility with both 230V AC and DC voltages, and a contact current rating of 6A. Wiring is simplified with a screw terminal type, and the device features a cable entry size of M20 x 1.5 for flexible cable management.

The switch is designed to operate reliably within a temperature range of -25°C to 85°C and can withstand up to 1,000,000 mechanical cycles, ensuring long-term durability in demanding industrial settings. The trigger angle range of 10 degrees allows for precise actuation, and the actuator head’s ability to rotate in 22.5° steps facilitates versatile mounting and application.
