Rugged switch based on Hall Effect sensor coding introduced by Elma for military uses
May 22, 2013
FREMONT, Calif., 22 May 2013. Elma Electronic Inc. in Fremont, Calif., is introducing the X4 rugged switch based on Hall Effect sensor coding technology for devices that must withstand harsh environments as found in the construction, transportation, industrial and defense industries.
Hall Effect sensing technology offers reliability and performance where conventional switches would not survive, such as in the presence of dust and vibration.
Elma's X4 series Hall Effect Sensor Coded Switch has a 5-bit gray code output with 12 or 24 positions for resolution as well as parallel analog and PWM outputs. The X4 is available in two indexing angles, either 30 or 15 degrees. Selectable switching torque is available, and the indexing mechanism has a life of as many as 100,000 switching cycles.
Designed to meet IP68 (with optional sealing), the X4 switch has a stainless steel shaft and zinc housing for high humidity and salt atmosphere environments. It also is resistant against a variety of other environmental stress factors like shaft load, shock, vibration, water pressure, and fire.
The rugged design enables the X4 switch to operate in temperatures from -30 to 85 degrees Celsius, and it meets MIL-STD-202G and MIL-STD-810F for humidity.
The switch can be customized with different shaft styles, connectors and cabling as well as electrical interfacing such as CANbus, SPI and I2C. This family of X4 series Hall Effect sensor coded switches includes versions for audio applications, including one for audio attenuation.
