Vibration Switch Guards The Fort

Hansford Sensors’ compact HS-429 vibration switch is designed to protect machinery against unexpected shutdown and repair costs. The switch automatically trips in the event of excessive vibration levels, allowing critical systems to be shut down before damage can occur. It is said to be one of the most compact vibration switches on the market, enabling the continuous monitoring and protection of assets in tight spaces.


The component is designed to transmit a 4 mA to 20 mA signal, features an adjustable false trigger delay of up to one minute to prevent error trips, which may occur at machine start up, and is overload protected to a maximum shock of 100g. The HS-429, which features a MEMS accelerometer integrated on the microchip, is exceptionally quick and simple to set up, with the maximum RMS velocity set point and response delay time easily adjustable using two rotating setup dials. It is sealed to IP67 and designed to perform reliably within a temperature range from -25°C to +80°C. For more good vibrations of knowledge, peruse the product page.
