Deemed as some of the most cost-effective miniature incremental encoders around, the OPE1275 and OPE2275 single- and dual-channel encoders are designed specifically for use in printer motors, machine automation, and machine safety equipment. The components deliver 256 pulses per revolution at speeds of up to 5,000 rpm and are easy to install, using only a Phillips screwdriver. Extended shaft versions are fully assembled and ready for immediate connection. The OPE1275 provides a single-channel analog output for speed of rotation, while the OPE2275 device provides a dual-channel analog output for speed and direction of rotation. Connection is via a four-pin connector providing V+, ground, and output pins. OPTEK TECHNOLOGY INC., Carrollton, TX. (972) 323-2200.
