ST series safety sensors with RFID technology Introduction In combination with the corresponding safety modules, the sensors of the ST series are suitable for the monitoring of protective devices on machines without inertia and allow the system in which they are used to reach a safety category up to SIL 3 acc. to EN 62061 as well as up to PL e and Category 4 acc. to EN ISO 13849‑1. These sensors use RFID (Radio Frequency IDentification) technology and provide high protection against possible manipulation thanks to the uniqueness of the codes transmitted by the actuator. Because they have no mechanical...

Laser engraving Pizzato Elettrica supplies a pro‑ grammable version of the ST series sensors. With a simple and brief ope‑ ration, the sensor can be program‑ . med to recognise the code of a new 0.. 011 actuator. 010 0 By activating a special input, the sensor is switched to a safe state, during which it waits for a new code to be accepted. As the actuator approaches, the ST sensor performs a number of checks on the code being received, whereby the code must adhere to certain parameters of RFID technology. If the checks are successful, the sensor uses LEDs to signal the suc‑ cessful completion...

Limit activation zone and safe activation zone (ST D^4«m) When aligning the sensor with the actuator, the status LEDs use various colours to indicate whether the actuator is in the limit activation zone or in the safe activation zone. The following figures use the ST DD420MK-D1T sensor as an example. Oldl rffjt /// ACT IN OUT PWR Operating voltage is applied to the sensor, (LED PWR on, green), the inputs are enabled (LED IN on, green), the outputs are deactivated (LED OUT off).
