Sensors

Presentation

Our range of sensor products is constantly expanding. Many of our sensors are designed specifically to customers requirements, especially components for the automotive market.

Our in-house capability to solve application problems efficiently is well known. As manufacturer of electronic and electromechanical components, STG has also specialized on customer specific, automotive sensors.

As a longstanding partner of the automotive industry, STG manufactures a variety of sensors for the most demanding safety applications, such as e.g. ABS- and seatbelt systems.Here are some examples of our extensive product range:

The automotive sensor / ABS sensor

 

is designed utilizing several pendulum sensors (see left picture above). When the preset acceleration is exceeded the pendulum with the fixed magnet detects and activates the Reed Switch. The sensor can be adjusted for accelerations above 0,1g. Other customer specific automotive sensors such as door lock sensors and the like can also be designed.

 

 

The acceleration sensor / crash sensor

 

can detect axial accelerations with an adjustable response value beyond a prespecified g-force (multiple gravitational acceleration). When the prescribed acceleration is exceeded a flying magnet passes a Reed Switch triggering contact. Typical automotive applications include airbag and seatbelt systems. The accelaration sensor can be adjusted for accelerations above 2g to meet preselected customer acceleration requirements as well as other design/package specifications.

 

 

Pendulum sensor:

 

A magnet mounted on a pendulum passes a Reed Switch when the sensor is tilted or accelerated. This activates the Reed Switch. Differential angles above 2° are available. The repetitive accuracy of the sensor allows its use for very high precision requirements, for example in the automotive industry.

 

 

The magneto resistivo sensor

 

can detect and measure very low magnetic fields. Speed and rotation of moving parts can thus be detected at substantial distances up to 1.000 mm between magneto resistivo sensor and magnet. The numerous possibilities concerning supply voltage, output signal, sensitivity, temperature and housing design can meet individual user secifications.
