8 APPENDIX D - SMC-LRS-04 HIGH-POWER LASER
ADAPTER
8.1 INTRODUCTION
The High-power Laser Adapter provides convenient connectivity from the SMC Laser Connector (J18)
to industrial automation-style connectors. A subset of the SMC digital laser control signals has been
reconditioned to drive 24V circuitry, which is typically seen in high-power fiber lasers from IPG and in
differential drive circuitry for CO2 lasers from Coherent. In addition, the High-power Laser Adapter
provides a local laser modulation signal that is remotely switchable and adjustable to facilitate laser
alignment for CO2 lasers.
The High-power Laser Adapter has the following features:
• 24V digital laser modulation, gate and power signals, and a differential RS-485
modulation signal exposed on two 12-pin 3.5mm plug-in Phoenix Contact strips
• Single-ended 5V TTL modulation signal exposed on a BNC connector
• Local laser modulation generation with remotely switchable on/off and power (duty-
cycle)
Mating connectors for the 3.5mm Phoenix Contact strips are available from many sources. The
screw-type mating connector number is MC 1,5/xx-ST-3,5 where xx is the number of pins.
