Xenon Strobe Beacon

Upgraded Product

  • Lower in-rush electronics
  • Enhanced light output
  • A4 316 stainless steel guard as standard

Description

The STExB2X21 beacons produce a high output Xenon flash required for effective signalling in environments with elevated levels of ambient light. The field replaceable colour filter enhances the strobe and is constructed from UV stable PC. The stainless steel enclosure features a threaded flame path, four cable entries and a large termination area – all of which significantly reduce installation time. SIL1 & SIL2 Route 2H compliant to IEC61508 (2010) as standard.
