FAQs

What makes the NJDC-17 relay different from standard miniature relays?

It includes a self-locking test button, allowing manual circuit verification and maintenance without live operation interruption — a feature not common in standard relays.

What mounting options are supported?

The NJDC-17 is available in plug-in (PLU) and PCB-mount (PIN) versions, suitable for both panel and printed circuit installations.

How many contact configurations are available?

You can choose from 2Z, 2ZS, 3ZS, and 4ZS contact sets, supporting up to 4 changeover (4C) contact outputs.

What indicator and protection options are available?

The relay can be equipped with LED status indicators, surge suppression circuits (for DC models), and arc shields (for 4ZS types) for enhanced safety.

What environments can it operate in?

It performs reliably from −40 °C to +70 °C, with shock resistance up to 200 m/s² and vibration durability up to 55 Hz, making it ideal for harsh industrial conditions.
