Posital’s Magnetocode (MCD) absolute rotary
encoders are available with heavy-duty stainless steel housings that make them
ideal for use in harsh environments. The rugged housings and highly effective
seals provide these devices with IP69K level of protection. Mounted on sturdy
ball-bearings, the shaft can withstand mechanical forces of up to 300 N (67
pounds).
Posital MCD encoders use a highly reliable
magnetic measurement technology that provides 12-bit resolution (4,096 steps
per revolution). Multi-turn models are available with a range of up to 8,192
revolutions (13-bits). The internal rotation counter uses a unique self-powered
technology that eliminates the need for backup batteries, further reducing
maintenance requirements. These low-cost encoders are available in a simple SSI
interface that features several user-defined parameters that simplify initial
set-up. They are also available with the more sophisticated CANopen field bus
interface, commonly used by mobile equipment manufacturers. An analog interface
(4-20 mA or 0-10 V) is also available, making these encoders a highly-reliable
alternative to potentiometers. DeviceNet and SAE J1939 interfaces will be announced
in the near future.
