SN series
Hall effect T-bar fader
Overview
MECHANISM
The SN series utilizes high quality ball bearings at the pivot point of its lever and uses a PTFE friction clutch assembly
to create a smooth, damped, put and stay feel of the lever to ensure a consistent feel over the life of the product.
POWER SUPPLY
The SN series is designed to be powered by a regulated 5V±0.5V power supply. The output is ratiometric, making
a stable, noise free, power supply essential. The power supply to the SN series should be carefully regulated to be
within tolerance. Should the power supply change outside specified tolerances, permanent damage may occur.
MAGNETIC IMMUNITY AND SYSTEM DESIGN
The SN series faders incorporate magnetic shielding, however, mounting or operating the SN series close to strong
magnetic fields is not recommended. System designers should follow best practice when incorporating the SN series
into their products. Care should be taken to disconnect the power supply properly and to employ adequate EMC
shielding.
MOUNTING
When mounting the SN series, care should be taken to site it in a position that does not make it vulnerable to
damage when in use. The SN series must not be subject to water spray, excessive humidity or dust. The handle is
supplied separately, in two halves that must be screwed together after the SN series has been mounted to the panel.
GAIN OPTIONS
The voltage output on the wiper, at full scale deflection is determined by the gain. The gain is expressed as a
percentage of the voltage supplied. Therefore (assuming a 5V supply), a SN series specified with ±25% gain would
yield 1.25V at South and 3.75V at North. A range of gain options are available as standard.
All SN series are supplied pre-set and no further calibration is needed throughout the lifetime of operation.
OUTPUT IMPEDANCE
The voltage output at the center and at each end of travel are specified across an infinite load, with no current
flowing. The output impedance specified in the electrical specification should be taken into account when designing
a system. Load resistance of less than 10K Ohms is not recommended.
CONNECTIONS
The SN series are supplied with three solder post connections.
Additional cable outputs and customer specific
connectors are available on request.
