Elma switches are designed into audio, aircraft, industrial automation, construction, laboratory and test and measurement products. The company offers a wide range of rotary switches and encoders from commercial grade through to products fully compliant with aerospace and defence systems. The new X4 is the rotary switch for the toughest requirements, boasting an extremely robust rotary switch platform with an optional push button function. The switch incorporates a unique magnetic, Hall effect (contactless) sensing system, to ensure maximum ruggedness, reliability and life expectancy. The micro-controller-based circuitry provides absolute code (Grey) with analogue and PWM, or encoder output. The MR50 multi-functional rotary switch is a ½” selector switch designed for portable outdoor devices, military radios, aiming systems and vision devices, test and measurement equipment and instrumentation as well as aircraft cockpit applications. Just ½” in size, the MR50 offers up to 16 switch positions, switching torques of up to 6 Ncm, and operates either in shorting or non-shorting modes. With gold-plated contacts (3-micron gold), the switch offers protection up to IP68 and performs in operating temperature ranges from -45 °C to +85 °C. Elma's E33 product enhancements are particularly well suited for mobile applications targeting public safety, and all E33 series encoders feature Elma's exclusive Swiss Click Indexing System that ensures consistent turning torque over the encoder's entire lifetime. Standard features include 16 or 32 detents resolution, optional integrated push button, rotational life up to 1,000,000 revolutions, optional IP68 front panel sealing, MIL-STD-202G compliant and operating temperature range from -40 to +85°C.
