Encoders Handle Low-Speed Applications

A family of single- and dual-channel incremental encoders provides designers with a selection of miniature devices designed for general encoding of low-speed applications. Designated the OPE1275 single-channel (tachometer) and OPE2275 dual-channel encoders, these analog-output encoders are designed for small-shaft motors with a diameter of 2 mm (0.079 in.) and a minimum length of 3.8 mm (0.150 in.). The encoders feature 256 pulses per revolution, with a maximum of 5000 RPM. The single-channel device features a rise and fall pulse, providing two slopes for each pulse and thus doubling the count capability. The rise and fall pulse of the OPE2275 encoder is in a quadrature pattern, providing design engineers four times the pulse-per-revolution count. Typical applications for the single- and dual-channel encoders include printer motors, machine automation, and machine safety. Frequency response ranges from DC to 25 kHz, providing a maximum of 256 cycles per revolution (CPR) and 1024 quadrature states per revolution (PPR). Typical rise and fall times are 500 ns and 100 ns, respectively. Pricing for the OPE1275 and OPE2275 incremental encoders is approximately $23.89 each in quantities of from one to 99 pieces. Lead time, if stock is not available, is from six to eight weeks. OPTEK TECHNOLOGY, Carrollton, TX. (972) 323-2200.
