The Series 52 offers the bounce-free electronic valve signaling required for all PLC, computer and solid state circuitry vital to process control and information networks. Costly external junction boxes are eliminated and field wiring costs are greatly reduced.Bray’s approach delivers the most compact, reliable and economical valve position monitoring system available.
• Models: DC NPN, DC PHP, AC, I.S., DeviceNet, PROFIBUS, ASi
• Electrical Connections: Inductive: M12(4 pin), 7/8"(5 pin)
• BUS Network: ASi Flat Cable, DeviceNET, ASi M12
• Housing: Valox
Moisture, Chemical and Corrosion Protection
The two proximity sensors are completely encapsulated with epoxy resin in a rigid polymer enclosure that is impervious to moisture and most chemical and corrosive agents. Once the multi-pin connection is made, the cable link to plant wiring is completely sealed eliminating the possibility of failure due to moisture. These protections make the Series 52 the best choice for hostile environments.
A multi-pin electrical connector is designed for full compatibility with today’s industrial wiring requirements.
Bray’s design of two sensors in one rugged enclosure greatly reduces space requirements and expensive housings needed for previous dual switch applications. The epoxy resin encapsulation protects the sensors against vibration or shock.
Local Position Indication
A Valve Position Pointer, made of highly visible yellow ABS material, shows valve position locally throughout the full range of travel.
• LED Indicators give positive verification that the sensors are electrically functioning and show the target position has been reached.
• High Visibility Valve Position Display: (optional) Prominently labeled and color coded – yellow for open, black for closed – the display indicates valve position throughout the full range of travel.
The Bray Series 5A and 5B Valve Status Monitors (VSM) provide visual and electrical indication of position on any VDI/VDE 3845 compliant quarter-turn device. Our solutions enable end users to better monitor their process no matter the conditions.
Enclosure: The compact low-profile weatherproof VSM is UL certified 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.
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 limit switch to change position indication.
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.
Captive Cover Bolts: The cover is attached to the base by captive stainless steel bolts placed outside the sealing area.
Protective Washers: Clear, nonmetallic, corrosion resistant washers are used to ensure coating integrity when cover bolts are tightened.
O-Ring Seal for Watertight Enclosure: The O-ring seal between the cover and base provides a weatherproof seal preventing internal corrosion.
Sensor Cams: Splined cam design allows for easy and accurate setting of switch activation without the use of tools.
Limit Switches: Multiple limit switch options and configurations to meet connectivity requirements.
Terminals: Clearly marked terminal blocks are angled towards the user to ensure easy access.
Conduit Entries: Two conduit entries available in either imperial or metric threads.
Grounding: Green color-coded, easy-access grounding bolt.
