protection for stage overtravel. Their physical location is shown in
Component
Description diagram on page 16 they and can be adjusted up to 30 mm (1.2 in.)
toward the center of travel. The electric characteristics are shown here.
• Input Power: 12 … 28V DC, 15 mA circuit draw + 50 mA maximum
sourcing = 65 mA total.
• Output: PNP, Open collector Normally Closed, 50 mA maximum
sourcing.
