WAGO 1.5MHz DIN-rail Optocoupler

Germantown, WI – February 2012 – WAGO Corporation’s DIN-rail mount 859-940 High-Speed Optocoupler features a frequency input range of up to 1.5MHz. Engineered by WAGO’s Custom Products Division, 859-940 provides jumper-selectable, industry-standard input voltages of 5–10VDC or 10–24VDC. The 6mm-wide Optocoupler serves high-speed machine vision applications and quality testing with voltage conversion and isolation, as well as signal and level amplification.

Initially a bespoke, customer-driven design and now a WAGO Standard product, the high-speed 859-940 Optocoupler offers isolated data transmission. It also enables PLCs (typically 24V inputs) to read devices with 5–10V outputs. Optocoupler applications include high-speed camera imaging (food, packaging and process) and QA testing (machine-building). The 859-940 can mimic a frequency counter for testing input modules, or simulate an encoder for convenient machine testing prior to shipment.

Based on WAGO’s industry-proven 859 Series Relays, the Optocoupler employs CAGE CLAMP^® Spring Pressure Connection Technology for vibration-proof terminations. Additional features: an output drive capability of 75mA (max. resistive), input status LED indicator and operating temperature range of -10^°C to +45^°C. The RoHS-compliant 859-940 is manufactured at WAGO’s Germantown, WI headquarters and is in stock.

WAGO is the leader in spring pressure connection technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products: DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; the WAGO-I/O-SYSTEM and more.
