Allen-Bradley 440N-Z21SS2B
Overview
The Allen-Bradley 440N-Z21SS2B is a rugged RFID-coded non-contact safety switch designed for harsh industrial environments, particularly in food, beverage, and pharmaceutical applications. Featuring a 316L stainless steel housing and an IP69K rating, this model resists corrosion and high-pressure washdowns. It provides 2 N.C. safety outputs and 1 N.O. auxiliary output, with pre-wired cable connection for simple installation. The RFID coding offers a high level of tamper resistance and reliable guard position monitoring.
