Product catalog summary
Product Overview
The E37 Encoder is a versatile component designed for various applications, offering both vertical and horizontal mounting options. It features a dual encoder system, allowing two encoders in one space, with resolutions of 16 or 32 detents. The encoder can be customized with different shaft dimensions, shapes, and materials, including stainless steel housing. It is suitable for cockpit controls, radios, and portable audio equipment.

Specifications
  • Mounting Options: Vertical or horizontal, threaded or non-threaded bushing.
  • Push Button Force: Options of 3, 6, 10, 14 N, or without push.
  • Resolution/PPR: 32/16, 32/8, 16/16, 16/8.
  • Switching Torque: Ranges from 0.5 to 4.5 Ncm or no detent.
  • Sealing: IP60 or IP68 for front panel sealing.
  • Operating Temperature: -40 to +85 °C.
  • Rotational Life: Up to 1 million revolutions.
  • Electrical Connection: Pins 0.23 x 0.8 mm, with a switching voltage of < 15 VDC and current < 10 mA.

Mechanical and Electrical Data
The encoder supports a rotational speed of < 60 rpm and a phase shift of 90° (±70°). It has a contact resistance of < 10 Ω and an insulation resistance of > 1 GΩ at 500 VDC. The encoder is designed to withstand environmental conditions such as humidity and vibration, complying with MIL-STD-202G standards.

Customization and Accessories
Customizations include shaft dimensions, switching torque, and push button actuation force. Accessories such as hex nuts and various knobs are available for different shaft types. The encoder is packaged in blister boxes of 20 pieces, with nuts supplied separately.

Environmental and Material Specifications
The encoder is made from high-quality materials, including stainless steel and brass, with gold-plated contacts for durability. It is designed to operate in harsh environments, with IP68 sealing available for enhanced protection.

Ordering Information
The datasheet provides a detailed ordering code system to specify the desired configuration, including bushing type, resolution, torque, push button force, and sealing options.
