Multi-turn absolute encoders
29 January 2019
Sensata Technologies introduced the availability of MHM5 and MHK5 Absolute Multi-Turn encoders with either Ethernet/IP or ProfiNet interfaces for Factory 4.0 applications. To provide additional design flexibility, these encoders are available in either shafted (MHM5) or blind shaft (MHK5) configurations.
These model MH encoders provide up to 16 bits per turn and 14 bits of turns counting. The packaging allows these encoders to be integrated into existing designs while an operating temperature range (-40 to +85C) and an IP65 rating makes them suitable for most industrial applications.
Included in the design is a geared turns counter that is immune to electrical or magnetic interference. In addition, these encoders feature reverse polarity and short circuit protection as standard. These specifications help to ensure speed and position sensing across many industrial processes.
Multi-turn encoders are used in packaging applications where they help to identify the position of products along the process line to determine when the machine needs to take an action such as to die cut, mark, slit, inspect, singulate, and/or stack. Another common application when encoders are used is in metal forming – such as determining the absolute position of strips, bars, rolls or tubes of metal being carried along a process, that need to be marked, scored, slit, inspected, or formed.
Absolute Multi-Turn encoders like models MHM5 and MHK5 are also often used to determine the angle of rotation and position of a crane boom, as well as the amount of cable payout. They are also useful in heavy vehicles for off road mobile platforms, construction and mining equipment.
