PB150 — Explosion Proof GRP Push Button
The PB150 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 Glass-Reinforced Polyester 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 316L stainless steel enclosure, see the PB125.
