POSITAL has extended its portfolio of rotary encoders with a line of through-hollow incremental encoders. The devices are designed to be installed with the machine shaft passing through the sensor.
They can be used to monitor rotary motion in a wide variety of machinery, including servomotors, material handling equipment and printing presses, offering cost-effective, space-saving solutions.
For motors, they are said to be easily installed between the body of the motor and other components mounted on the shaft.
The encoders are available for shaft diameters ranging from 3/8 in. (9.5 mm) to 1-3/4 in. (44.5 mm).
The smaller units (up to 14 mm shaft opening) have an external diameter of 2-1/4 in. (58 mm), while the larger units (5/8 to 1-3/4 in. shaft size) have external diameters of 3 or 4 in. (77 or 100 mm).
Available resolutions for these devices extend from 360 to 4096 ppr.
Units are rated at IP65 and are available with a variety of communications interfaces, including RS422 (TTL) 5V or 11-30V and Push-Pull (HTL, 5-30V).
Connection options include built-in cables or MIL-type connectors.
