Overview of the Electrical Interface

5.1

Input Power

The Tau camera operates from DC power per the specifications given below. It is common in
simple operational scenarios to use an inexpensive wall-powered adapter. The Tau VPC
accessory makes this easy by providing a USB connection.
The camera operating in a steady-state condition consumes around 1W of power. During start
up or when the shutter is operating for the camera's periodic calibration, peak power levels of
5W (sustained for less than one second) are typical. Typically, start-up times are between three
and four seconds.
Caution!
Reversing the polarity of the input power will damage the camera's internal power supply.
This damage will not be covered under the camera warranty.

The Tau core is tested per EN55022 Class B for radiated emission with and without the rear
cover. The emissions are below the Class B limit with the back cover off; and below the Class A
limit with the back cover on. It is the responsibility of the systems integrator to verify EMI/EMC
compliance at the system level.

Hirose 50-Pin Connector

In the Tau camera's simplest form (no accessories attached), one connector provides the
electrical interface. This connector is a 50-pin Hirose board-to-board style connector, per
Hirose Part Number: DF12-50DS-0.5V(86). Hirose offers a variety of mating connectors
including their SFM(L), SMT, and SFSD style products. The primary Tau connector at the rear of
the camera is identified in the figure below:
