BL series

Miniature paddle joystick controllers

Overview

The BL series paddle joysck is conﬁgured as two “electrical” controls in one mechanical package. The Paddle operates from

5V and provides two proporonal outputs. The second output is accurate to the ﬁrst within ±3% of the power supply. The

power supply for the secondary output is also completely independent. Customers may choose their preference of voltage

outputs (gains).

The secondary output can be of the same or inverse polarity to the primary wiper. For example, with a secondary inverse

output, the ﬁrst and second outputs can be summed and compared to zero to verify that the joysck is operang correctly.

Paddles having two idencal outputs of the same polarity may be used to drive two idencal dual redundant circuits.

There are also two Hall eﬀect switches that trigger at pre-determined lever posions.

The BL series paddle joysck may be speciﬁed with a variety of PWM output opons. For more details on available PWM

opons please refer to APEM.

SELECTABLE SWITCHING POINTS

The Paddle incorporates two Hall eﬀect switches. The angle of the lever at the switch trigger point can be selected when

ordering. If no switches are speciﬁed then the output on pins 2 and 7 will be unused. The outputs are conﬁgured as

‘open drain’ type with a 1K5 pull up resistor to 5V.

GAIN OPTIONS

The voltage output on the wiper, at full scale deﬂecon is determined by the gain. The gain is expressed as a percentage

of the voltage supplied. Therefore (assuming a 5V supply) a Paddle speciﬁed with ± 25% gain would yield 1.25V at South,

2.5V at center and 3.75V at North. A range of gain opons are available as standard. All controls are supplied pre-set and

no further calibraon is needed throughout the lifeme of operaon.

OUTPUT IMPEDANCE

The voltage outputs at center and at each end of travel are speciﬁed across an inﬁnite load, with no current ﬂowing. The

output impedance speciﬁed in the electrical speciﬁcaon should be taken into account when designing a system. Load

resistance of less than 10K Ohms is not recommended.
