Control Logic presents the Schmersal AZ300, a new range of mechatronic safety switches featuring an RFID based electronic safety sensor and IP69K rating.
The Schmersal AZ300 mechatronic safety switch incorporates a distinctive external Maltese cross shaped cam, which allows it to accept the actuator from any of three sides, providing mounting flexibility for left or right-hinged doors, or sliding guards.
The integrated radio frequency identification (RFID) sensor detects the actuator and indicates a closed guard, with the non-contact operating principle limiting wear on the AZ300’s components, tolerating misalignment, and offering the option of individual coding. The basic version of the sensor responds to any AZ300 target actuator; the I1 version only accepts the coded ID number of the specific target actuator taught in during the first start-up; and the I2 version allows the teach-in process to be repeated, enabling replacement of a lost or damaged actuator.
The AZ300 mechatronic safety switches feature all of the diagnostic advantages of Schmersal Pulse Echo sensors. With continuous internal function tests and monitoring of the safety outputs, the AZ300 can be wired in series without detriment to the safety levels. Diagnostic LEDs on the sensor indicate various errors, misalignment and door open/closed signalling. The AZ300 is also available with serial diagnostics for more advanced indication.
The AZ300 also offers adjustable latching to provide a holding force of 25 N or 50 N. The AZ300 actuator includes a dampener pad so that the switch can be used as a door stop for small to medium sized guard doors. Lockout/Tagout can be achieved by placing padlocks through the key of the actuator, preventing the guard from closing.
The new AZ300 meets the requirements of Cat 4, Performance Level e or Safety Integrity Level 3. The IP69K rating makes the switch suitable for use in hygiene-sensitive areas.
