ifm efector introduces Non-Contact, Fail-Safe Inductive Sensor and Multi-Function Relay Approved for Safety Applications
 
 


More information
 Fail-safe inductive sensor does not rely on a coded magnet or keyed target for safe operation

• Wear-free, one-piece solution replaces the traditional two-piece safety switch by integrating ifm’s patented, non-contact inductive sensing principle that is rated up to Category 4 according to EN954-1 for safety applications.
• Similar to an inductive proximity sensor, ifm’s fail-safe sensor can detect any standard metal target such as stainless or mild steel.
• The sensor’s extended sensing range – up to 15 mm –provides a high tolerance to misalignment and nuisance tripping in shock and vibration environments.

The technology that enables an inductive sensor to be used in safety applications

• The compact 40 x 40 mm fail-safe sensor offers reliable sensing using ifm’s “window technology” that continuously detects a target within its enable zone – or window.
• If the target moves outside its enable zone, the sensor will fail to safe. The window technology also compensates for conventional approach angles and closing door angles.
• The sensor features setup and output status LEDs and two safety PNP switching outputs.
• Can be connected to any standard safety relay or safety PLC currently available in the market.

ifm also introduces a new multi-function safety relay

• Compatible with various safety devices that include e-stops, light curtains, protective guards, two-hand controls and safety sensors.
• Versatile, all-in-one safety relay eliminates the need for multiple product-specific relays and reduces relay stock levels.
•Two N.O. safety contacts are rated up to 6A and a solid-state auxiliary non-safety output.
• Dual channel safety devices can be configured to monitor simultaneous logic and cross-fault detection across the inputs.
• Compact housing is only 22.5 mm, providing up to 50% space savings in a control cabinet.
• Certified to IEC 61508, EN 954-1, EN 574 type IIIC.
