Rotary Switches
Grayhill is the leading manufacturer of Single-Deck Rotary Switches and Multi-Deck Rotary Switches with extremely rugged construction and virtually limitless configurations. Many of our rotary switches are MIL-qualified to exacting electrical, mechanical, and environmental standards. We offer many options: isolated positions, spring returns, adjustable stops, concentric shaft switches, and configurable keylock switches.
Rotary Switches →Touch Encoders
Grayhill's Touch EncoderTM combines the functionalities of a touchscreen, a keypad, and a rotary switch into one. The device supports USB or CAN J1939 communication. Furthermore, it is IP67 sealed and has an impact-resistant design. The vivid display comes with a 320x300 high resolution. The encoder is built to withstand at least 1 million rotational cycles. With highly customizable widgets, the Touch EncoderTM has the versatility to fit into a myriad of user interface applications such as aerospace, automation, robotics, and marine.
Touch Encoders →Mechanical Encoders
Mechanical encoders combine the feel of our rotary switches with a digital output. They provide an economical way of obtaining octal, binary-coded decimal, hexadecimal, and gray code output from a rotary switch. Standard products include offerings with concentric shafts, isolated positions, and adjustable stops.
Mechanical Encoders →Optical Encoders
Grayhill specializes in optical encoders with optional joysticks and pushbuttons that provide outstanding haptic feedback to the user. The most significant advantage of optical encoders is their non-contact switching technology, resulting in exceptionally high operational life. Although the end product may vary, typical applications measure speed, distance, and/or rotational angle.
Optical Encoders →Machine Rotary Encoders
Grayhill's high-resolution Machine Rotary Encoders provide excellent tactile feedback to the user, making them a reliable choice for various applications. They feature debris-resistant Hall-effect sensor technology and are available in multiple cycle options. Users can also choose between sealed and unsealed versions for more demanding environments or standard models. With a sturdy construction and options for cable or pin configurations, these rugged encoders are designed to withstand rigorous use and boast an impressive operational life of up to 10 million rotational cycles.
Machine Rotary Encoders →Hall-Effect Encoders
Hall-effect technology provides contactless operation, facilitating a long operational life. The sensor magnetically detects the position of another moving part, such as the shaft in a joystick or encoder. This relational position can be outputted from the device in various formats, including I2C, open collector, or push-pull output. Hall-effect technology has the advantage of working in low-voltage applications and often features a sleep mode to conserve power.
