Automation Direct MAFK1-A0-1H Magnetic Proximity Sensor

MAFK1-A0-1H is a tubular magnetic proximity sensor from AutomationDirect featuring an 18 mm diameter, 60 mm long 316L stainless steel housing. It provides a PNP, normally open output through a 4‑pin M12 quick‑disconnect and offers a 70 mm nominal sensing distance in flush-mount configurations, making it ideal for harsh, washdown environments where non-contact sensing is required. With a 5 kHz switching frequency, this sensor supports fast detection in high‑speed automation and packaging lines, while its IP68 and IP69K protection ensure dependable operation under heavy spray and rugged conditions. The unit is UL listed (UL File E328811) and RoHS compliant, reflecting recognized safety and environmental standards. Note that MAFK1-A0-1H was retired in February 2023 and is no longer available new from AutomationDirect; the recommended replacement is MAFK1-AP-1H. Its stainless steel construction and compact tubular form factor suit integration into machinery where corrosion resistance, reliable proximity sensing, and straightforward panel or machine mounting are priorities.
