PILZ Safe Automation has released AS 4024.1 Category 4 mechanical safety switches that, when used with Pilz control systems, can prevent access until an area is safe. The PSENmech switches are also easy to install, connecting to all common control voltages.
The solenoid version of the Pilz PSENmech switches work on the principle that entry is only allowed once an area is safe as indicated by a safety timer or safe standstill detector. This can be critical where machinery takes time to reach zero energy status. Typical control systems to match the PSENmech are the PNOZ and PNOZmulti safety relays, the programmable safety system (PSS) and the open bus systems.
Safety is enhanced by the PSENmech's mechanically coded actuators, which comply with EN 1088t. The switch can only be actuated by the correctly matched actuator.
Teamed with a non-contact safety switch, such as PSENcode and PSENmag, and Pilz control systems, the PSENmech can form part of a diverse and redundant complete safety solution for applications rated at up to Category 4 under AS 4024.1 and EN 954-1 standards.
The compact design is paired with radius or standard actuators and accommodates up to eight actuation directions for maximum flexibility in tight spaces.
