Magnetic safety switch for non-contact cooperation with actuator, transmits security code in code portions that are smaller than full data block length of security code in sections between actuator and switch

摘要

The switch (1) comprises control output (4,5) that generates a disabling signal, if the distance (D) between safety switch and actuator (9) is set above or below predetermined limit value, such that switch is established with in range of wireless data communication to share a security code with a predetermined burst length. The security code in code portions that are smaller than full data block length of security code is transmitted in sections between actuator and switch.
