RFID Coded Switches with Safety Interlock

RFID coded switches with safety interlock (IDEM RFID series, e.g. SPF, LMF) — contactless safety devices for reliable access control in hazardous areas. Using RFID technology with magnetic coding, they provide high tamper protection, dual verification (RFID + magnetic field) and Type 4 coding compatibility. IP67/IP69K sealing, built-in LED indication and service life over 1 million cycles make them ideal for food, pharmaceutical and machine-building industries.

Specifications RFID coded switches with interlock

• Housing material: Plastic (polyester) or AISI 316 stainless steel — impact-, vibration- and corrosion-resistant, washable.

• Coding: RFID with magnetic actuation (Type 4, high anti-tamper), sensing distance 8–14 mm with up to 5 mm misalignment tolerance.

• Contactless operation: RFID + magnetic field, zero mechanical wear, no sparking (ATEX compatible).

• Contacts: 2NC + 1NO (or OSSD for series connection), solid-state.

• Electrical parameters: 24–230 V AC/DC, 0.2–4 A, IP67/IP69K.

• Size: Compact models (e.g., 22 mm fixing for SPF, M30 for LMF), M4/M5 screw or adhesive mounting.

• Temperature: -25…+80 °C (up to +100 °C for steel versions).

Advantages RFID coded switches with interlock

RFID technology with coding ensures:

• high safety level (SIL 3 / PL e, PLe / Cat. 4 per ISO 13849-1);

• resistance to CIP/SIP cleaning and aggressive environments;

• series connection up to 20–30 devices without safety loss;

• LED status indication (green — active, red — fault). Contactless technology minimizes failure risks, enhances reliability and simplifies installation.

Applications contactless RFID coded switches

• Food industry: Door interlocks on conveyors and packaging lines.

• Pharmaceuticals: Access control in clean rooms with hygiene requirements.

• Chemical industry: Protection in explosive zones (ATEX on request).

• Machine building: Safeguarding moving parts of machines, robots and equipment.

Installation and connection RFID coded switches

1. Secure housing with screws or adhesive base.

2. Position RFID actuator at 8–14 mm distance.

3. Connect cable (standard 2–5 m, M12 8-pin quick connect options). Maintenance — visual inspection; compatible with safety relays (e.g., IDEM SCR).
