Features and Benefits

Switch Box Series 5C Features and Benefits

A Enclosure

Compact, weatherproof VSM is UL certified NEMA Type 4, 4x and IP66/67/68. Aluminum base and cover provide excellent corrosion, wear, and impact resistance.

B High-Visibility Position Indicator

Impact-resistant dome indicator provides visual open and close indication. To reverse the open and close visual output, simply rotate the indicator dome 90 degrees. Position indication can be changed without removing the switch box aluminum cover and exposing the internal wiring of the VSM.

C Neck Secondary Seal

Ensures the indicator area is isolated from the internal area of the VSM. The secondary seal prevents water ingress if the dome or dome seal is damaged due to harsh field conditions.

D Captured Cover Bolts

The cover is secured to the base with stainless steel captured bolts located outside the sealing area.

E Washer

Stainless steel corrosion-resistant washers provide a larger contact surface for the captured bolts, securing the cover to the base.

F O-Ring Provides Weather Protection

An O-ring seal between the cover and base provides weatherproof sealing to prevent water ingress and internal corrosion.

G Cam Sensor

Splined cam design allows easy and accurate switch trip point adjustment without tools.

H Limit Switches

Up to six switch options and configurations to meet connection requirements.

I Terminals

Clearly marked terminal board is angled toward the user for ease of installation.

J Conduit Entry

Three conduit entries available in imperial or metric threads.

K Grounding

Green-coded, easy-to-operate ground bolt.

FAQ

How does the Bray Series 5C switch box provide valve position monitoring in hazardous locations?

The Series 5C detects valve open, closed, and intermediate set positions via limit switches and provides on-site visual feedback through a dome high-visibility indicator. The product carries CE, cULus, ATEX, IECEx, and SIL 3 certifications, suitable for hazardous location applications requiring reliable valve position feedback. Specific configuration should be confirmed based on actual model and application conditions.

What switch types and signal configurations are available for the Series 5C?

The Series 5C can be configured with mechanical SPDT, DPDT switches, or proximity PNP, NPN switches, with up to 6 switches available. The spline cam structure allows tool-free switch trigger position adjustment for accurate setting. Specific switch combination should be confirmed based on control system interface and valve feedback requirements.

What fieldbus communication protocols does the Bray Series 5C support?

The Series 5C supports AS-I, Profibus DP, and DeviceNet communication protocols, suitable for applications requiring valve status integration into automation control networks. Protocol selection should match the existing control system and actual model configuration.

What is the protection and environmental resistance of the Series 5C switch box?

The Series 5C offers IP66/67/68, NEMA 4/4X, and UL50E salt spray protection. Its aluminum base and cover provide corrosion, wear, and impact resistance. An O-ring seal between cover and base, plus a stem secondary seal, helps reduce water ingress and internal corrosion risk under harsh field conditions.

What installation and maintenance points should be considered for the Bray Series 5C?

The Series 5C is compatible with VDI/VDE 3845 (NAMUR) mounting standards. The product offers imperial or metric conduit port options, including 2x 3/4 inch NPT plus 1x 1/2 inch NPT, or 2x M25 plus 1x M20. Verify mounting interface, conduit thread, and environmental temperature requirements during installation. The operating temperature range is -25°C to 65°C. To reverse position indication, rotate the dome 90 degrees without removing the cover.
