The Bray Series 5A, 5B and 5C Valve Status Monitors (VSM) provide reliable visual and electrical position indication on any VDI/VDE 3845-compliant quarter-turn device. Series 5A offers lightweight, compact housing to fit the tightest spots. Compact IP66/IP67 certified switch box for industrial environments. High-performance visual and electrical position indication devices. Certifications: CE, cULus (most models), SIL 3 capable; optional: ATEX, IECEx. Temperature range: -25ºC to 65ºC. Switch options: mechanical SPDT (low power); proximity PNP, NPN, 140 V 2-wire, 250 V 2-wire, reed, NAMUR intrinsically safe.
A. Enclosure: the compact low profile weatherproof VSM is UL certified NEMA Type 4, 4x and IP66/67. A die-cast aluminum cover and base coated with a polyester powder coat for exceptional corrosion, wear, impact and ultraviolet resistance.
B. High visibility position indicator: visual open and closed indication is provided with an impact resistant dome style indicator. Inverting the open and closed visual output is easily done by removing the dome and rotating it 90 degrees. There is no need to remove the cover and expose internal wiring of the VSM to change position indication.
C. Stub shaft secondary seal: ensures indicator area is separate from the VSM’s internals. Provides a secondary seal to prevent water ingress should the dome or dome seal become compromised due to adverse site conditions.
D. Captive cover bolts: the cover is attached to the base by captive stainless steel bolts placed outside the sealing area.
E. Protective washers: clear, nonmetallic, corrosion resistant washers are used to ensure coating integrity when cover bolts are tightened.
F. O-ring seal for watertight enclosure: the O-ring seal between the cover and base provides a weatherproof seal preventing internal corrosion.
G. Sensor cams: splined cam design allows for easy and accurate setting of switch activation without the use of tools.
H. Limit switches: multiple switch options and configurations to meet connectivity requirements.
I. Terminals: clearly marked terminal blocks are angled towards the user to ensure easy access.
J. Conduit entries: available in either imperial or metric threads.
K. Grounding: green color-coded, easy-access grounding bolt.
