PB125 — Explosion Proof Stainless Steel Push Button
The PB125 is a flameproof manual push button for potentially explosive atmospheres. ATEX and IECEx certified for gas and dust zones and SIL2 compliant, it triggers alarms and emergency alerts and interfaces with PLC, ESD or DCS systems.
The 316L stainless steel housing with a UV-resistant coating suits corrosive and hazardous areas. Two versions are available — self-reset and key-reset push-pull — with one or two changeover contacts. Optional LED indication, lift flap and line detection extend monitoring and safety. Ambient range is −40°C to +70°C.
For a GRP enclosure, see the PB135 or PB150.
Typical applications: oil and gas, petrochemical, chemical plants, offshore platforms, marine, hazardous-area process control.
