New LPF Series and SPF Series safety switches use RFID (Radio-Frequency Identification) coded communication between switch and actuator to provide the most tamper-proof protection. These non-contact safety switches are designed to protect both people and machines in applications where no physical contact takes place between the switch and actuator. LPF Series and SPF Series safety switches provide LED indication of the RFID coded actuation and have a switching capability up to 0.2A. These switches are IP69K rated and will operate with most safety relays. When used in combination with a Dual Channel Safety Relay, RFID Coded non-contact safety switches can be used to provide protection up to Category 4 and PLe to ISO13849-1. Starting at $104.00, the RFID coded safety switches are available with a 2m, 5m, or 10m pigtail; or a 250mm Q-D cable.
