Công tắc an toàn không tiếp xúc RFID với đầu ra OSSD LPZ IDEM: RFID Non Contact Safety Switch with OSSD Outputs LPZ

IDEM’s LPZ “Intelligent Series” Non Contact Switches have been developed to provide and maintain a high level of functional safety whilst providing tamper proof RFID coded activation.

The LPZ will connect to most popular standard safety relays to maintain a PLe/Category 4 Safety level even with switches connected in series.

They are offered in high specification plastic housings and can be used in virtually any environment including high pressure cleaning following contamination from foreign particles.

They have IP69K ingress protection and are suitable for CIP and SIP cleaning processes.

They are supplied with easy to understand LED diagnostic functions and provide auxiliary outputs for extra diagnostic signals to PLCs or computers.

The typical sensing distance “on” is 12mm with wide tolerance to guard misalignment after setting.

Coding is achieved by using magnetic and radio frequency techniques, both principles need to be satisfied for the switch to operate safely.

The RFID sensing provides a tamper resistant operation when the actuator is in the sensing range of the switch.

The LPZ switches are available in two versions:

Version 1: TYPE M. Master Code – by series (any actuator will operate any switch) used when unique door activation is not required, but the benefit of RFID makes it virtually impossible to be over-ridden or by-passed by simple means.

Version 2: TYPE U. 32,000,000 Unique Codes. These switches are factory set and used when UNIQUE activation is required in areas where there are many interlocked doors and security of individual areas is required.
