Strip Type Big Power Relay YX218

Switching Timing & Endurance

• Operate time: 10 ms maximum at nominal coil voltage, measured from the coil being energised to the contacts closing, so allow for it where a sequence depends on the load being live.
• Release time: 5 ms maximum without a diode across the coil. Add suppression and the release behaves differently, so check the timing on the bench before freezing a control sequence.
• Mechanical endurance: 1 × 10⁵ operations. In an power relay that cycles all day under light load, the actuator is rarely the part that wears out first.
• Electrical endurance: 1 × 10⁵ operations at rated load.

The sealed type encloses the contact chamber, keeping dust, moisture and flux residue away from the contacts, which is the usual pick for humid rooms, dusty plant areas and boards that pass through a washing stage. The open type leaves the contact set exposed, so it suits clean, dry cabinets where contacts can be inspected and heat has an easier path out. Tell us where the relay will operate and we will confirm which construction fits; please specify yours alongside the model, coil and contact form. Every unit is assembled and tested at our own plant, so you are buying from a relay manufacturer rather than through a reseller.
This model can be perfect replacement of HF118F alternative.
