Heavy duty encoders for extreme environments

BEI Sensors has launched the LP series of low profile encoders designed for high reliability position and speed feedback in harsh and challenging environments. Available in the UK through Variohm EuroSensor, the IP66 rated encoder utilises innovative sensing technology with a choice of incremental or absolute single-turn output that allows for accurate position and speed feedback for demanding applications in industrial manufacturing, processing industries, agriculture, oil & gas and building automation.

The encoders’ environmental specification includes an operating temperature range of - 40 to 100°C; shock is rated to 3000m/s2 with vibration to 200m/s2.

The LP series features an aluminium housing with a nominal square size of 90mm and is offered in three model variants with programmable resolution versions and a choice of shaft interfacing and electrical termination options. A compact cable or connector version facilitates straightforward installation in confined spaces whilst a terminal box option makes safe pre-wiring a possibility. Both options are offered with a width of 26mm whilst the third version is a 51mm wide ATEX-IECx rated explosion proof model with terminal box.

Incremental encoder versions have HTL-TTL outputs with a maximum resolution of 10,000ppr and are available with a programmable resolution which also provides commutation channels. Absolute versions feature a single turn resolution of up to 16-bits with an SSI output – also available as a programmable option. Enhanced electronics options on some models provide protection against mis-wiring, overvoltage protection up to 60V, and strong signal output for longer cable runs.
