Description

The VR504 barrier laser was developed for the requirements of the steel industry. This powerful barrier laser is designed for penetrating the heaviest steam and furnace flames; yet it is a totally safe Class I  Laser. This dependable barrier laser works even under the most difficult conditions, such as high temperatures, vibration, high dust concentrations and contamination, without problems.

The VR504 barrier laser is available in three models to suit individual requirements. All models include a 2 Amp, 30VDC/125VAC Form C relay output. Green “Power” and Red “Alarm” LED’s provide a visual indication of operation and alarm state. Model VR504-K includes a secondary alarm output, adjustable to a predetermined level for indicating lens contamination and misalignment. Model VR504-T operates at a faster detection frequency and includes an adjustable alarm response time from 8 - 350 msec.

Encapsulated within a robust IP65 rated stainless steel housing these lasers are specifically built for mounting in the harshest environments. An optional totally encased air or water cooling jacket is available that facilitates mounting close to furnaces or hot product. Optional bolt-on tempered glass shields are available to prevent lens damage.

Additional options include a LSS-36 Swivel and Lift Mounting Stand and a LAK-504-01 Laser Alignment Kit. The LSS-36 Stand provides a convenient mounting with adjustments in the X, Y & Z axis. The LAK-504-01 Alignment Kit includes a snap on battery operated transmitter laser pointer and a snap on receiver reflector. The kit aids in aligning the transmitter with the receiver during initial set-up and maintenance.

All VR504 barrier lasers are totally safe Class I  Lasers and have no working restrictions and do not require any additional protection.
