Connecting the lens

All EL-10-30-Series lenses have an electro-magnetic motor, which is driven by current. The lens will only work
with the correct polarity of the current. False polarity will not damage the lens.

EL-10-30 (compact version)

The EL-10-30 has a simple copper cable connection. The correct polarity is shown in Figure 1:

Figure 1: Connection of the EL-10-30. The colored cable is the

positive terminal and the copper cable is the negative terminal.

EL-10-30-C (C-mount version)

The EL-10-30-C has an FPC connection compatible with Molex 0.5mm pitch 6 way FPC backflip connector (P/N
503480-0600). An adaptor board with integrated connector is included for easy soldering. The connector on
the adaptor board has top and bottom contacts so it is important that once orientation is established it must
be maintained.

The EL-10-30-C also features an integrated NXP SE97B temperature sensor with 256 bytes of memory – the
sensor is addressable via the pins as detailed below:
