Avtron M738-1D-240-BTC Pulse Generator Module

Avtron M738-1D-240-BTC is a rugged rotary pulse generator (zero-speed transducer) that converts shaft rotation into a fixed number of electrical pulses—specifically 240 pulses per revolution—so feedback is proportional to travel or speed. Powered from 12–15 V DC and drawing roughly 230 mA, it provides two independent, dual-isolated outputs (one on each side) for feedback flexibility in control systems. The device uses a large, non-breakable disc positioned between an infrared source and four photoreceptors, all housed in a cast aluminum enclosure with a steel shaft and sealed bearings for industrial reliability. The 1D configuration indicates dual outputs; the BTC suffix denotes connector options that include Bidirectional operation along with a Terminal Block interface and an MS-style connector output. With zero-speed capability, it continues producing pulses even when the connected machine is at rest, supporting precise position or travel measurement in automation tasks. Common applications include motor control feedback, servo loops, and legacy Avtron encoder systems requiring compact, rugged pulse generation with multiple output/connectivity options.
