The Laurel IPC Splash-proof Cover is a rugged, impact resistant, clear lens that fits over a 1/8 DIN instrument to make it dust and water proof from the front of the panel. Sealing meets NEMA 12 (IP52) standards for water splash and dust protection when the hinged door is simply snapped in place. Sealing meets NEMA 4 (IP67) standards for hose-directed water when the hinged door is further clamped down with a provided plastic locking key.
The IPC fits all Laurel 1/8 DIN instruments as well as 1/8 DIN instruments by other manufacturers, provided that instrument dimensions in front of the panel do not exceed 48 x 96 x 15 mm (1.89" x 3.78" x 0.59"). The IPC can be purchased as an add-on option for new instruments, or be fitted to existing installations.
The IPC assembly utilizes a clear base and clear door with a cam hinge. The hinge is captive when the base and meter are installed, and allows the door to be opened for easy access to the meter for programming or setpoint adjustment. The base can be sealed against the instrument panel by an O-ring or a self-adhesive neoprene gasket, both provided.
A capillary seal is formed between the door and the base by a tapered recess in the door and a tapered ridge in the base. Capillary action causes a small amount of water to be drawn in between the two surfaces, thereby producing a water-tight film around the sealing area. For applications where fluid residues are unacceptable, such as food processing, apply a light coating of clear silicone grease, or other approved sealant, to the mating grove to prevent any ingress of liquid and enable the cover to withstand steam cleaning.
The door is latched against the base by a locking tab when the door is snapped shut. Positive clamping of the door and protection against opening of the locking tab by hose-directed water are provided by a locking key, which remains in place to provide a much higher clamping force than the tab alone.
The Laurel IPC is easy to install. It utilizes the existing 1/8 DIN panel cutout (45 x 92 mm). No new panel holes are required.
