Safety Limit Switches

Safety limit switches — mechanical and contactless devices for detecting end positions of moving equipment parts, with interlock and emergency stop functions. Made of AISI 316 stainless steel or high-tech plastic, with lever/roller heads and springs for precise actuation. Compliant with EN ISO 14119, IEC 60947-5-1, IP67/IP69K protection and PL d / SIL 2 safety level. Ideal for food, pharmaceutical, machine building and chemical industries.

List of Safety Limit Switch Types

TypeShort Description

INCH-1

Plastic housing, 1NC/1NO, roller lever, IP67 — universal for standard applications.

INCH-3

Plastic housing, 2NC/1NO, rotary lever, IP67 — for precise positioning.

INCH-1-SS

Stainless steel 316, 1NC/1NO, roller, IP69K — hygienic for food industry.

INCH-3-SS

Stainless steel 316, 2NC/1NO, lever, IP69K — for aggressive environments.

INCH-1-MAG

Contactless magnetic, 1NC/1NO, IP67 — wear-free, for high-speed lines.

INCH-3-MAG

Contactless magnetic, 2NC/1NO, IP67 — with high safety level.

INCH-1-SS-MAG

Stainless steel + magnetic, 1NC/1NO, IP69K — hygienic contactless version.

INCH-3-SS-MAG

Stainless steel + magnetic, 2NC/1NO, IP69K — maximum reliability in washdown areas.

Specifications safety limit switches

  • Housing material: AISI 316 stainless steel (Ra4 polishing) or plastic (polyamide) — corrosion/washdown resistant (CIP/SIP).

  • Types: Mechanical with lever/roller, contactless magnetic; contacts 1NC/1NO, 2NC or solid-state OSSD.

  • Actuation force: 5–20 N (lever), precision ±0.5 mm; mechanical life >10 million cycles.

  • Electrical parameters: 24–250 V AC/DC, up to 6 A, IP67/IP69K.

  • Size: Compact models (e.g., 40 × 40 × 20 mm), M4/M5 screw mounting.

  • Temperature: -40…+100 °C.

Advantages safety limit switches

IDEM/STEUATE limit switches provide:

  • precise position detection with minimal wear (roller heads);

  • hygiene (FDA/EHEDG, smooth surface);

  • vibration/shock resistance (IK08);

  • flexible mounting (compatible with guards). Mechanical design ensures reliability in cyclic operations.

Applications safety limit switches

  • Food industry: Position control on conveyors, packaging lines.

  • Pharmaceuticals: Safeguarding moving parts in clean rooms.

  • Machine building: Machines, presses, robotic lines.

  • Chemical industry: Pumps, valves in aggressive environments (ATEX option).

Installation and connection safety limit switches

  1. Secure housing with M4 screws on moving/fixed part.

  2. Adjust lever/roller for end-position actuation.

  3. Connect cable (standard 2 m, M12 option). Maintenance — spring and contact check.
