E33 Series

The Type E33 Series from Elma is a high-performance miniature mechanical incremental encoder. Designed with Elma’s exclusive Swiss Click Indexing System which ensures consistent rotational torque over the encoder entire lifetime. These encoders are offered in either 16 or 32 positions and can be smooth action or including detent with switching torques between 0.5Ncm up to 4.5Ncm. For added functionality, the Type E33 series is available with a shaft pushbutton actuation offering a pushbutton force of 3, 6, 10 or 14N. The small housing dimensions of just 11.5 x 12.3 x 4.9mm allow the encoder to be incorporated into many designs and the THT or SMT reflow terminations allow for quick and simple installation. As with the majority of Elma products, there is a large range of shaft dimensions and shapes which match their plastic or metal knobs presenting designers with many aesthetic choices. To allow for easy assembly and integration the Type E33 series SMT version of encoders can be purchased pre-mounted onto a circuit board. These can be with or without a debounce circuit and have the option of being created with an FFC or Micro-MaTch Connector, ribbon cable or soldering connections. With a rotational life of up to 1 million revolutions and front panel sealing up to IP68 the Type E33 series is perfect for applications such as Avionics Instrumentation, Testing Equipment, Two Way Radio Devices, Medical Devices, High-End Entertainment Systems and many other Industrial Applications.
