Electronic fail-safe Sensors

For safety applications

Certified to EN 954-1, category 4 PDF-M to EN 60947-5-3. Safety monitoring of persons and Machines. No coded target required. Connection of the sensors to safety plc or AS-i module AC016S. Series connection of sensors and contacts.

Category 4 failsafe sensors
Special features of the units: For more explanations see the technical glossary chapter starting on page 256

Features A special counterpart such as a magnet or coded target is not necessary for the function of the sensor. The failsafe inductive sensor detects metals like stainless steel or mild steel. The sensor operates with an enable zone which is monitored for target position and dwell time. An adjustment mode facilitates mounting. With reduced mounting input up to 10 fail-safe sensors can be connected in series in combination with mechanical contacts. Wear-free, non-contact selfmonitoring operation and high protection rating ensure high uptime of the machines and installations. Non-contact fail-safe product or position detection is now possible, for applications in conveying processes roller lever switches or counterparts such as Magnets are no longer necessary. The input and output signals of the sensors correspond to DIN EN 61131 and are therefore fully compatible with the inputs and outputs of a plc. It is possible to connect them to ifm evaluation Relays, AS-i Safety at Work, PROFIsafe, Interbus Safety, safe logic modules and safe PLC with TÜV-certified Software modules.
