In mechanical safety, for access doors that prevent access to dangerous moving areas, it is usually necessary to use a safety interlock switch to achieve the “dream linkage” between the access door and the movement of dangerous equipment: when the access door is opened, the dangerous movement stops. In some cases, it is also necessary to ensure that the device is in a safe state before allowing the safety door to be opened, that is, the protective locking function.

Taking the equipment with high inertial movement as an example, the equipment needs to be completely stopped after receiving the shutdown instruction for a period of time to reach a safe state, then it is necessary to protect the locking function, until the movement of the equipment stops before the door is allowed to be opened.

PSEN slock is PILZ’s safety door system for monitoring access doors in dangerous areas, and with the introduction of the “upgraded” PSEN slock2, PSEN slock products will also be successfully retired from the stage of history.

PSEN slock2 can not only completely replace PSEN slock in function, but also increase the security level to reach the protection lock function of PL c in the case of security interlock, integrating security interlock and protection lock in one.

Function upgrade

The PSEN slock2 security interlock and security protection lock determine that the PSEN slock2 can be used for process protection and personnel protection of equipment. PSEN slock2 increases the maximum locking force to 2000N, which can better protect equipment and personnel. In addition, PSEN slock2 adds the function of adjusting the latch holding force, which can be adjusted between 30N, 110N and 200N by RFID tag or SDD, which greatly improves the availability of the lock.

Hardware upgrade

PSEN slock2 Compared with PSEN slock in addition to functional upgrades, in terms of hardware also improved. The PSEN slock2 is made of stainless steel components with a robust form factor and protection rating up to IP67/IP69K for use in harsh environmental conditions and in places with high hygiene requirements.

A complete solution for security gates or area protection

In the field of equipment, there are often multiple security doors, the common types of security doors are: revolving doors, sliding doors, hinged doors, etc., need to choose the appropriate security door system according to the application situation to ensure the safety of equipment and personnel. PSENslock is a versatile and versatile safety door system for most types of safety doors. The material of stainless steel is especially suitable for the environment with high hygiene requirements, especially suitable for the packaging, food and beverage and pharmaceutical industries.

In practical applications, in addition to the safety door system, it is also necessary to choose a suitable safety controller according to the number of safety functions of the equipment, such as the modular safety relay myPNOZ, the configurable small controller PNOZmulti2 or the automation system PSS 4000, in order to ensure the desired safety protection effect. Of course, with the improvement of equipment automation, the traditional solution of safety controller and safety sensor has been unable to adapt to the requirements of information and intelligent era, users can further integrate industrial information rights management, fault diagnosis and other functions, with a complete and efficient solution, for the safe operation of equipment, for production safety escort.
