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.

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.

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.

CAN BUS KEYPADS
Grayhill's second-generation CAN Bus Keypads Plus offer a low-profile snap-in mounting scheme, wide viewing angle LED indicators, built-in diagnostics capabilities, and two I/O pins (except for 6-button variants). The legends on this keypad will exceed the stringent off-highway requirements for abrasion, UV, and chemical resistance. Grayhill's legacy CAN Bus Keypads are available with J1939 or CANopen protocol to integrate onboard vehicle electronic systems seamlessly. Their sealed and compact construction makes them ideal for agriculture, construction, and mining vehicles. They communicate with any of the 3D Series CAN Bus Displays. Keypads are available in various form factors (6, 8, 12, and 15-button), supporting both the J1939 and CANopen protocols. These IP67-sealed keypads can have customized artwork and LED backlight/indicator colors.
