Elobau Sensor Technology Inc. introduces its 145MA micro push button for various industrial applications. This new control is based on Hall effect technology and provides a 0.5 to 4.5 Volts linear output proportional to the displacement of the actuator. It is designed to be incorporated in the knob of a joystick or a multifunctional handle for a shifter, or into a control panel. It provides an accurate proportional control of auxiliary functions.
The 145MA push-button from Elobau is only 27mm long, with a diameter of 16mm, and can be mounted through a Ø12mm hole. Similar to other Elobau push-buttons, the 145MA has different standard colors available for the actuator cap, and can be customized to accommodate specific symbols. The 145MA features reliable non-contact Hall effect sensor technology. A magnet moves along a Hall Effect sensor, located in the push-button housing. The total stroke is 4mm, and provides a ratiometric output voltage between 0.5 and 4.5 VDC. Supply voltage is 4.5 to 5.5 VDC. The current drain is 15 mA max. The electrical connection is through 3 wires, with a standard length of 500mm.
The non-contact sensing technology ensures a longer service life, guaranteed to two million switching operations. The 145MA push-button operates in a range from -40ºC to +85ºC (-13ºF to +175ºF). The robust rubber boot provides a IP67 protection class above the mounting panel.
