Autonics developed the SFN-M-020 for demanding Safety Non-Contact Door Switch applications. Operating on a stable 24VDC Β±10% supply, it delivers reliable position detection without physical contact, minimizing wear and extending service life.
This model offers an operating frequency of 100Hz with an OFFβON actuation distance of β₯5 mm and ONβOFF distance of β€15 mm, providing quick and accurate door status monitoring. The PNP open collector sub-output (24VDC, 10 mA) integrates easily with safety control systems, and its dual-color LED indicator allows clear status verification.
Constructed from durable polycarbonate with an IP67 protection rating, the SFN-M-020 withstands shock up to 30G, vibration from 10β55Hz, and operates between -10Β°C to 55Β°C. Learn more at Autonics Sensors & Controllers for industrial automation or the full range of Autonics Safety Door Switches.
The Autonics SFN-M-020 Safety Door Switch is ideal for securing machine access panels, robotic cell doors, and conveyor safety gates. Its non-contact operation prevents mechanical wear, making it suitable for environments with frequent access cycles. Engineers value its simple wiring and rugged build, while safety managers trust its consistent operation in high-vibration, moisture-prone, or dusty conditions.
