546989

Name: Festo 546989 Electrical interface VMPA-ASI-EPL-G-4E4A-Z
Brand: Festo

Electrical interface VMPA-ASI-EPL-G-4E4A-Z

The Festo 546989 industrial component measures 85 mm by 122.9 mm by 55.1 mm and features M12 socket and plug interfaces for AS-i Out and AS-i In connections. It supports up to 4 valve positions, a maximum of 4 inputs, and 1 slave per device with an IP20 degree of protection and CRC corrosion resistance class of 1. Device-specific diagnostics monitor AS-i voltage, AS-i address, watchdog/I/O status, and additional supply missing or undervoltage conditions across an AS-Interface DC operating voltage range of 26.5 V to 31.6 V.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
