Current Sensing Switch for precise monitoring and control Selfpowered sensing with mutual inductance technology provides input/output isolation and detects AC current from 0.2 to 30 A for reliable monitoring in industrial and commercial settings. Adjustable sensing relay function: Choose M3050 normally open or M3056 normally closed. Clear red and green LED indicators enable quick status identification and fast responses in complex environments. Power supply sensing switch specifications: Contact capacity 0.3 A at 240 V AC/DC; throughline diameter up to 10 mm; compact size 65 x 25 x 47 mm; hysteresis less than 1% for accurate switching with minimal mechanical wear. Robust and safe construction: Noncontact electronic switching allows unlimited activation cycles; flameretardant PC shell withstands strong magnetic environments and delivers longlasting performance. Benefits and practicality Noncontact sensing reduces wear and maintenance while providing reliable monitoring. Selfpowered operation eliminates the need for an external supply, simplifying installation. Input/output isolation enhances safety in control circuits and panels. Compact form factor enables easy integration into tight spaces and existing panel layouts. Clear status indication via red/green LEDs supports quick onsite diagnostics and faster responses. Typical applications Motor control and protection: monitor load current to trigger a guard relay or signaling device without direct contact on conductors. Building automation: control HVAC, lighting, or fans based on current thresholds in commercial environments. Industrial safety and energy management: implement interlocks or monitoring schemes in production lines where noncontact, durable sensing is beneficial.
