Surface Mount Magnetic Reed Switch Features High Sensitivity

Surface Mount Magnetic Reed Switch Features High SensitivityStandex Electronics introduces the SR4J series of ultra small surface mount magnetic reed switches for non-contact position sensing in pill cams and other medical devices. Over molded around a proven GR150 magnetic reed switch, this J leaded version measures just 4.7 mm in length and 1.7 mm in height. The external leads of the reed switch form a tear drop terminal pad arrangement which preserves a greater portion of the initial magnetic circuit, thus enhancing the magnetic sensitivity of the sensor. The SR4J series boasts a maximum sensitivity range of 3/5 Ampere Turns (AT) (initial), and is available in a production range from 3 to 20 AT.

In addition to a small footprint and tight sensitivity range, the SR4J series is responsive, with a typical operating time of 0.2 milliseconds, and release time of 0.1 milliseconds (typical). The switches have a power rating of 1 VA maximum. A switching current (Max) of 0.05 Amp, DC is standard, as is a carry current rating (max) of 0.5 Amp, DC. Boasting an operating range of -40 to 125°C, the SR4J is well suited for use wherever small size and sensitivity are required for non-contact position sensing applications.
