Low-cost miniature incremental encoders from Optek Technology, the OPE1275 and OPE2275 single- and dual-channel encoders are designed specifically for use in printer motors, machine automation and machine safety equipment. The analogue output miniature encoders feature 256pulses/revolution at speeds of up to 5000RPM. The encoders are also easy to install, according to the company, requiring only a Phillips screwdriver for assembly. The extended shaft versions of the encoders are assembled and ready for immediate connection. The single-channel encoder provides a single-channel analogue output for speed of rotation, while the double-channel device provides a dual-channel analogue output for speed and direction of rotation. Electrical connection is achieved via a 4pin connector providing V+, ground and output pins. Frequency response ranges from DC to 25kHz, providing a maximum of 256 cycles/revolution and 1024 quadrature states/revolution. Typical rise and fall times are 500 and 100ns, respectively. Supply voltage (VCC) is 5V, while supply current (ICC) is 21mA. Operating temperature ranges from 0 to +85°C. Electronica: Hall A6: stand 301
