AutomationDirect's non-contact safety switches use RFID communication between switch and actuator for tamper-proof protection.0
AutomationDirect has extended their offering of safety products to include the LPF and SPF-series RFID non-contact RFID coded safety switches. These non-contact safety switches use RFID communication between switch and actuator to provide the most tamper-proof protection using both master and unique coded actuators. When used in combination with a dual-channel safety relay, the non-contact safety switches can be used to provide protection up to Category 4 and PLe to ISO13849-1. The IP69K-rated LPF and SPF-series operate with most safety relays and feature plastic housings, wide sensing distances (>10mm), and a high tolerance to misalignment after sensing. With switching capability up to 0.2A, models are available in unique-coded and master-coded styles with 2m, 5m, or 10m pigtail cables or a 250mm quick-disconnect cable. Female quick disconnect cables, in 5m and 10m lengths, and replacement master-coded actuators are also available.
