Eight relay families mapped to how buyers actually specify. Figures below are typical ranges collected from industry reference data, confirmed per SKU during RFQ.
The traffic-anchor category — HVAC systems, control panels and appliance switching. Cost-effective and widely stocked across the factory network.
| Parameter | Typical Range | Notes |
|---|---|---|
| Rated voltage | Up to 600V AC/DC | Confirmed per model |
| Rated current | Up to 100A | Contact configuration dependent |
| Contact form | SPDT / DPDT / 3PDT | Single or multi-pole |
| Typical certification | UL, CE, CCC, RoHS | Documentation supplied per order |
Compact, vibration-resistant relays built for 12V/24V vehicle electrical systems — lighting, fuel pumps, HVAC blowers, starter circuits.
| Parameter | Typical Range | Notes |
|---|---|---|
| Coil voltage | 12V DC / 24V DC | Vehicle system dependent |
| Rated current | 20A–80A | Model dependent |
| Operating temperature | -40°C to 125°C | Typical automotive-grade range |
| Typical certification | E-mark, ISO, RoHS | Documentation supplied per order |
Board-mounted relays for electronics and automation equipment — small footprint, high isolation between coil and contacts.
| Parameter | Typical Range | Notes |
|---|---|---|
| Coil voltage | 5V–48V DC | Logic-level options available |
| Rated current | 5A–30A | Model dependent |
| Mounting | THT / SMD | PCB-specified |
| Typical certification | UL, VDE, RoHS | Dielectric strength confirmed per datasheet |
No moving parts — fast switching and long cycle life for precision low-power control and frequent-switching applications.
| Parameter | Typical Range | Notes |
|---|---|---|
| Input voltage | 3V–32V DC | Control signal side |
| Output rating | Up to 480V AC / 100A | Model dependent |
| Switching type | Zero-cross / random-turn-on | Application dependent |
| Typical certification | UL, CE, RoHS | Documentation supplied per order |
Sequencing and timed switching for process control circuits — on-delay, off-delay and cyclic timing functions.
| Parameter | Typical Range | Notes |
|---|---|---|
| Timing range | 0.1s–24h | Model dependent |
| Timing accuracy | ±5%–±10% | Model dependent |
| Contact form | SPDT / DPDT | Single or multi-pole |
| Typical certification | CE, RoHS | Documentation supplied per order |
Holds switching state without continuous coil power — used where standby energy consumption matters (metering, battery-powered control).
| Parameter | Typical Range | Notes |
|---|---|---|
| Coil type | Single / dual coil | Set-reset mechanism |
| Rated current | 5A–30A | Model dependent |
| Set/reset pulse | Typically 5–20ms | Model dependent |
| Typical certification | UL, CE, RoHS | Documentation supplied per order |
Sealed magnetic contacts for fast, low-noise switching in test and measurement equipment.
| Parameter | Typical Range | Notes |
|---|---|---|
| Switching speed | Sub-millisecond | Model dependent |
| Contact rating | Low-power signal to 2A | Application dependent |
| Contact life | High cycle count (sealed contacts) | Model dependent |
| Typical certification | RoHS | Documentation supplied per order |
Forcibly guided contacts for emergency-stop and safety light-curtain circuits — compliant with machine safety standards.
| Parameter | Typical Range | Notes |
|---|---|---|
| Standard | EN ISO 13849, GB/T 14048.5 | Safety category confirmed per application |
| Contact configuration | Forcibly guided (positive-guided) | Required for safety circuits |
| Typical certification | CE, TUV, CCC | Documentation supplied per order |
| Application | E-stop, light curtains, interlocks | Risk assessment by integrator |
