Comprehensive new range of functional safety incremental encoders

24-04-2015 | Variohm | Subs & Systems

The recently announced new and comprehensive range of functional safety
incremental encoders from USA sensor manufacturer BEI Sensors is now
available in the UK through its exclusive distributor Variohm EuroSensor.

The TÜV Rheinland certified range is suitable for use in the highest
industrial safety related applications up to SIL3/PLe Cat. 4, and is
designed to EN ISO 13849-1, IEC/EN 61 508, and IEC/EN 62061 safety
standards. With Sine/Cosine analogue electronic output or a digital (TTL or
HTL) electronic output, which is an industry-first for safety encoders, the
range covers seven individual encoder models with a broad selection of
options to suit a wide variety of applications.

Options include resolutions up to 2500 PPR, 58 mm or 90 mm diameter
aluminium housings and a selection of shaft or through shaft drives with
cable or connector terminations. Stainless steel housings are available to
suit harsh or wash-down environments and high ingress protection ratings are
available up to IP69K for high pressure and high temperature wash-downs.
Further innovative safety features include additional bearings on
through-shaft models for extra support and positive shaft locks to prevent
the encoder sliding on motor shafts, plus tether arms for safe mounting on
the driving motors. Insulated secure sleeves have been introduced to protect
against stray currents.

A 10-page White Paper - 'What the new Machinery Safety regulation means for
your company' - is available from Variohm to support automation engineers
and system integrators who need to implement functional safety on their
machines, says the company.
