Reduce Downtime and Save Costs with Dual Output Encoder |
The new dual output option for the HS35 hollow shaft encoder from BEI provides redundant encoder signals to ensure maximum control system reliability. This feature uses two sets of internal electronics to send identical isolated output signals to two separate connectors. If one output becomes electrically damaged, simply move the cable from one connector to the other. Your downtime is measured in minutes, not hours or days.
The dual output feature also has the capability to supply two separate controllers from a single encoder. Since the connectors are mechanically parallel and electrically isolated, connecting to a second controller and routing the cable is straightforward. Now you can save the cost and space of a second encoder with a single installation.
The HS35 is a heavy-duty hollow shaft encoder with a rugged cast metal housing and dual preloaded bearings for robustness and reliability. Rotating shaft seals and a sealed connector give it NEMA 4, 13 and IP65 ratings. It can accommodate a variety of shaft bores, up to 1 inch in diameter, and has a compact installed package length of about 2 inches. The HS35 is ideal for equipment with constrained axial encoder mounting space.

New Large Bore, Rugged, Hollow Shaft Encoder |
BEI’s
newest and largest-bore hollow shaft encoder is
ideal for large motor feedback applications. The HS45 accepts
motor shafts up to 1 5/8 inches in diameter (1 - 7/8 inches
optional) and provides data for position and velocity control.
This model incorporates the precise feedback capabilities
of an optical encoder with an easily mounted configuration
to larger motors. There is no need to step down or alter
most large motor shafts.
The HS45 encoder provides
an option for dual electrically isolated outputs. Should one
set of outputs sustain electrical damage, a quick change of the
connection enables you to get back up and running quickly. Alternatively,
the dual output can also be utilized to feed two different controllers
from a single encoder. This ensures speed and/or position synchronization
without the cost of an additional encoder.

Multi-Turn
Encoder Features Electronic Reset |
BEI
introduces a multi-turn absolute encoder, the
HMT25, with electronic
reset capability. Unlike manual resets (buttons
or switches) an electronic reset can use system
software for initialization. This greatly improves
machine set-up time, especially in systems with
space constraints. Sending a timed pulse through
the reset pin, the encoder value gets set to “zero” through
a non-volatile internal memory. Since the encoder
uses a geared multi-turn code wheel system, instead
of a battery-dependant electronic turns counter,
the physical position at any time is precisely
determined even in prolonged power down situations.

BEI Introduces Anti-Dither Module
|
|
Controller
seeing too many counts? Losing position in your control system?
High vibration environment causing false counts? BEI’s DIN
rail mountable electronic module can help. By comparing the quadrature
outputs on your encoder, the Anti-Dither
Module can remove the unwanted part of the signal and give you
a true picture of your system output.
Web
processes, conveyors, in-line inspection stations, and heavy equipment
operations are all subject to possible system errors caused by mechanical
vibration. This causes jitter on the encoder signal and subsequent
position and speed errors in the control electronics. BEI’s
Anti-Dither Module, placed between the encoder and the receiving
electronics, removes this type of error making sure the real data
signal ends up at the controller.

BEI Introduces Intrinsic Safety Barrier
|
|
The Intrinsic
Safety Barrier is galvanically isolated, eliminating the need
for an earth ground. It also combines both power and signal barriers
into a single package instead of the three or more separate packages
that were needed in the past. Output options, including differential
line drivers, make the barriers directly compatible with the majority
of counters, controllers and PLCs. The DIN rail mountable package
makes it easy to incorporate into standard enclosures and the built-in
LED indicator lights simplify initial setup and testing.
The barrier itself is rated as non-incendive
and can be installed in a Class I, Division 2 area. The requirements
of Class I, Division 1, Group C and D installations (Eex IA IIB
T4 CENELEC) can be met when used with properly rated encoders.

DIN Rail Optical Isolator for Encoders
|
|
BEI's Industrial Encoder Division
is the first encoder manufacturer to provide a DIN rail mountable,
optically isolated,
electronic module designed specifically for use with incremental
encoders. This optical isolator is part of a family of externally
mounted electronic packages recently introduced by BEI. Isolation
circuitry in this module acts as an encoder interface to provide
an electrically robust output to the receiving electronics. This
presents a solid solution for systems that are marginal due to poor
signal compatibility with the receiving electronics or installations
that are particularly susceptible to noise or grounding problems.
By providing a clean interface
between the encoder and the receiving electronics, this new optical
isolator can be used to eliminate ground loops, reduce signal degradation
from long cable runs (by acting as a repeater), or even provide
a means to distribute an encoder signal to multiple input devices.
The versatility of output options, coupled with an industry standard
package, means this electronic module can improve signal integrity
system-wide and ensure signal compatibility -- especially in systems
that incorporate a wide variety of controller interfaces.
