Sr. Application Engineer Dawn Etta explains pulse echo products and demonstrates serial diagnostic coverage.
Schmersal has developed and patented a proprietary technology known as Pulse-Echo. Sensors with this technology will evaluate the predetermined frequency of the actuator which is emitted after it has been triggered by an electromagnetic pulse. This operating principle allows for a non-contact actuation.
Because of an integrated dual monitoring microprocessor, only one switch is required to meet PLe per ISO 13849-1 and SIL3 per IEC 62061. These models can be wired in series with up to 31 devices without degradation to the safety levels. In addition to the LED visualization located on the switch to indicate operating statuses and errors, each switch has a diagnostic cable with the option of communicating its status via serial data packages.
The AZM400 is a motorized bolt lock with an integrated RFID sensor.
The AZM400 is a locking switch for machine guard doors that must be secured for safe operation. It provides a locking force of 10,000 N to keep the guard door securely locked until dangerous conditions, which may exist even after removal of power, have abated.
Since the locking bolt is motorized, the AZM400 is both power-to-lock and power-to-unlock. It is bi-stable in the event of a power failure, which maintains the last locked status of the interlock. It is available with a manual by-pass or an emergency exit knob (T) if the unit is mounted inside the hazardous area, which allows the bolt to be retracted manually. There is a version available with an electric manual release (E), which allows the unit to be hooked up to an auxiliary power supply to allow the motor to retract the bolt.
Do you find it difficult achieving effective machine guarding? Is it complicated applying the wording from regulatory and industry standards into practice? This webinar will help put some practicality to machine guarding, thus reducing the arguments against properly implementing machine safety guarding systems.
