Panel Mount Solid State Relay for Packaging Machinery
Fast, silent switching for sealing bars, shrink tunnels, hot-melt glue systems, cartoners and form-fill-seal machines. Omron and Carlo Gavazzi panel-mount SSRs with matching heatsinks β authorized supply across India.
Common Packaging Applications
- Horizontal and vertical FFS machines β jaw and side sealer heaters.
- Shrink wrap tunnels β IR / convection heater banks.
- Hot-melt glue units β tank and hose heater control.
- Cartoners and case sealers β tape or glue application heaters.
- Blister and strip pack machines β forming and sealing platen heaters.
Recommended Panel-Mount SSRs
Selection Notes for Packaging Lines
| Switching Frequency | Very high β zero-cross SSR strongly recommended. |
|---|---|
| Typical Loads | 10β30A per sealer / heater zone at 230V. |
| Heatsink | 1 Β°C/W or better; forced cooling for continuous operation. |
| EMI | Zero-cross switching keeps EMI well within CE limits. |
| Protection | Semiconductor fuse in line to protect SSR from shorts. |
Frequently Asked Questions
Why use SSR instead of contactor on a sealing bar?
Sealing bars switch several times per package. Contactors wear out in weeks under this duty; SSRs last for years with no mechanical wear.
Which SSR is right for a 15A sealing bar at 230V?
A 40A zero-cross panel-mount SSR (Omron G3NA-240B or Carlo Gavazzi RM1A23D50) with a 1 Β°C/W heatsink gives ample margin.
Can the same SSR be used for hot-melt glue tanks?
Yes. Hot-melt tanks are resistive loads well within these SSRs' capabilities.
Do you provide fast dispatch for line downtime?
Yes, stocked models ship same-day across major Indian cities.
