LITTELFUSE 59166-1-U-00-D Reed Switch, SPST-NO, 5.1 mm, SMD, -40°C to 125°C, 59166 Series

59166-1-U-00-D is a 59166 series miniature over-moulded reed sensor 16.00mm x 2.40mm x 2.40mm with straight or gull-wing leads. It is provided with normally open contacts. Its package contains moulded stand-offs to allow board washing. Reed contacts last for millions of operating cycles under micro-controller voltage and current logic-level loads. It is well suited for position and limit sensing, security, and door/window alarm systems. Hermetically sealed, magnetically operated contacts continue to operate long after optical and other technologies fail due to contamination. It is certified for use in north American hazardous locations: class I, division 2 and zone 2. It is also used in applications such as security system switches, door, and window proximity, sensing, metering, automotive electronics, anti-tamper detection, and small appliances. Functions best with the 57045 actuator.
