Safety Switch, Nonfusible, Indoor/Outdoor, Plastic

Idem 404201 rfid coded non contact switch lp replacement act master idem's lpf-rfid and spf-rfid non contact coded switches have been developed to provide and maintain a high level of functional safety whilst providing a very high anti-tamper coded activation. Coding is achieved by using magnetic and radio frequency techniques, both principles need to be satisfied for the switch to operate safely. They will connect to most popular standard safety relays to achieve up to ple/category 4 to iso13849-1. They are offered in high specification plastic housings and can be used in almost any environments including areas where high pressure cleaning is a requirement following contamination from foreign particles. Both switches have ip69k ingress protection and are suitable for cip and sip processes. The typical sensing distance on is 14mm with wide tolerance to guard misalignment after setting. The rfid sensing provides a tamper resistant operation when the actuator is in the sensing range of the switch. Lpf-rfid and spf-rfid switches are both available in two types either coded by series or uniquely coded. Type 1: lpf-m-rfid or spf-m-rfid 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 overridden or by-passed by simple means. Type 2: lpf-u-rfid or spf-u-rfid unique code - 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.
