NAIS ANR5131 – Compact Industrial Control Relay for Reliable Panel Interlocking and Signaling

The NAIS (Panasonic Industry) ANR5131 is widely used as a panel relay in control cabinets where you need dependable interlocking, status signaling, or small motor/solenoid switching. From my experience, it’s the kind of relay maintenance teams keep on hand because it drops into standard DIN-rail sockets, fires cleanly on a stable DC coil, and typically holds up well under daily cycling. You might notice that it balances size and contact capacity nicely, which is why it shows up in machine tools, packaging lines, and building automation panels so often.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than 1 month at the latest
• Payment: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Stable DC coil operation – Typically 24 VDC, giving consistent pull-in with low coil power.
• Clean, durable contacts – Designed for frequent switching of control signals, lamps, and small loads.
• DIN-rail/socket mounting – Quick replacement during maintenance; keeps panel work fast and tidy.
• Visual status – In many cases supplied with LED indicator or mechanical flag for quick diagnostics.
• Finger-safe handling – When used with standard protective sockets or covers, it helps reduce accidental contact.
• Good shock/vibration resistance – Suitable for factory floors and mobile equipment control boxes.

Technical Specifications

Note: Values below reflect typical configurations for ANR-series panel relays. If you’re matching an existing part, share the coil voltage and contact form so we verify pinout and ratings.

Application Fields

• Machine tools and material handling – interlocks, status lamps, solenoid valve control.
• Packaging and food & beverage lines – sensor signal isolation and small actuator switching.
• HVAC and building automation – fan starters, damper position feedback, alarm outputs.
• Power distribution and switchboards – auxiliary contacts, trip signaling, breaker interlocks.
• Transportation equipment panels – where shock and vibration resistance is handy.

A maintenance lead from a bottling plant told us the ANR series “seems to be the least fussy relay in the cabinet — swap it, clip it down, and it just works.” That’s fairly typical feedback we hear when uptime matters.

Advantages & Value

• Reliability under daily cycling – Contact design suited for frequent switch operations in control loops.
• Compatibility – Fits common DIN-rail sockets; wiring pinout aligns with typical control relay footprints in many cases.
• Serviceability – Fast replacement reduces downtime; no programming or commissioning.
• Cost-effective spares – Stocking a few relays can cover multiple cabinets and machines.
• Technical support – We can help confirm coil voltage, contact form, and socket choice before shipment.

Installation & Maintenance

• Cabinet environment – Install in a ventilated control cabinet; avoid condensation; keep within rated temperature.
• Mounting – Use a compatible plug-in socket on 35 mm DIN rail; fit a hold-down clip if vibration is expected.
• Wiring – Use ferrules on stranded conductors; tighten to socket torque spec; separate power and signal wiring where possible.
• Coil protection – For DC coils, a diode or surge suppressor across the coil typically improves longevity of upstream electronics.
• Routine checks – Inspect for heat discoloration, pitted contacts, or chatter; function-test during scheduled downtime.
• Spare policy – Keeping at least one spare per panel is a practical approach for critical lines.

Quality & Certifications

• Conformities typically include CE; many NAIS relays are also UL/CSA recognized and RoHS compliant (varies by sub-variant).
• Manufacturer’s standard warranty practices apply; our supplied warranty coverage is 365 days.

Supporting Components (Optional)

• DIN-rail relay sockets (finger-safe), matching the ANR pin layout
• Hold-down clips and socket covers for vibration-prone applications
• Coil surge suppression modules (diode/ZNR) for DC circuits
• Marker strips and ID tags for panel documentation

If you share the exact coil voltage and contact configuration required on your panel (e.g., 24 VDC coil, 2 Form C contacts), we’ll confirm the ANR5131 match and socket pairing before shipping. That small check usually saves time on site.
