Tilt switches (QG series)

A tilt switch is a type of switch that switches at a certain angle as compared to the horizon (similar to the old mercury switch). It is in fact an inclinometer with a switching output. Since gravity serves as a reference (same as for inclinometers) and because of the possibility to mount the sensor anywhere, maximum mounting freedom is achieved.
Tilt switch - DIS Sensors
The new generation of tilt switches from DIS Sensors are based on MEMS technology and intelligent microcontroller algorithms. As a result, single or twin axis switches can be implemented with any desired switching angle. The output can be NPN or PNP. An internal buzzer is available as an option. All in a QG40 housing. Even more accurate tilt switches with higher thermal stability can be executed using the QG65 housing.

The tilt switch housing

Many of the DIS sensors in the QG range use a unique universal plastic housing concept, known as QUADRO®. The advantage is the very compact size, simple installation and the fact that the electronics are fully sealed which provides a high degree of ingress protection (IP67). The housing is also available in metal (aluminum and stainless steel).

Types of tilt switches

DIS tilt switches are available with the following general specifications:

single axis measurement range:up to 179°
double axis measurement range:±1° to ±80°
energy supply: 5 V dc or 10 - 30 V dc
output:single or dual NPN/PNP
level of protection:IP67, IP68 or IP69K
precision:depending on model and range: as high as ±0.1°
programmable:switching angle, on/off delays, filtering
housing:(reinforced) plastic
