Incremental Encoder comes with or without center push switch.

Press Release Summary:




Suited for car audio and navigation systems, Series EC11J 11 mm sized incremental encoders feature resolution of either 18 detents and 9 pulses or 30 detents and 15 pulses per rotation, depending on model. Units offer bushing length of 5, 7, or 10 mm and push-pull-strength of 100 N. Optional SPST push-on switch is rated for switching currents of up to 1 mA at 5 Vdc, requires operating force of 5±2 N, and has 100 mW maximum initial contact resistance.

11mm Sized Incremental Encoder with/without Center-Push Switch and Long Operating Life



Ideal solution for car audio and navigation systems

Duesseldorf, Germany, November 21, 2007 - With the EC11J series, ALPS ELECTRIC EUROPA GmbH offers a new family of 11mm incremental-type encoders. The surface-mountable devices are available in a wide selection with or without center-push switch. They are remarkable for their long operating life with up to 1,000,000 switching cycles and 1,000,000 rotational cycles. The encoders have a metal shaft 6mm in diameter and an operating length of ca. 13mm. They feature a resolution of either 18 detents and 9 pulses or 30 detents and 15 pulses per rotation, depending on the model. The necessary detent torque amounts to 10mNm. Further technical specifications include a bushing length of 5, 7 or 10mm, and a push-pull-strength of 100N. The output signals of pins A and B are proportionate to the phase difference.

The center-push switch is designed as single-pole single-throw push-on switch and is rated for switching currents of up to 1mA at 5VDC. It requires an operating force of 5±2N. The actuating travel of the switch amounts to 0.5±0,3mm or 1.5±0.3mm respectively. The maximum initial contact resistance is specified for 100mΩ. The shaft-wobble is less than 0.2mm p-p (bushing length 10mm type) and therefore 30 percent less than previous models.

The EC11J series provides a body height of 4.5mm. With a compact floor space of 11.7mm x 14.2mm, the incremental encoders can be mounted even on high-density printed circuit boards without any problem. The new encoders are rated for voltages of 5VDC and have a maximum operating current of 10mA with resistive load. Their operating temperature ranges from -40°C to +85°C.

With the new EC11J series, ALPS meets the trend towards higher performance in conjunction with compact design. The combination of encoder and center-push switch and in particular the reduced shaft wobble provide a comfortable operation and a more accurate feeling when using the shaft. Typical applications of the EC11J series are volume adjustment or menu selection for car audio and car navigation systems.
