This machined block of solid aluminum provides for rigid jacketed, 3-wire 22 AWG conductors with stranded shield and 100% foil shield mounting using the two included 8-32 x 1/2 screws. The one screw split- coverage for noise immunity and is oil and water resistant. Connector/cable clamp design allows for easy adjustment of airgap and locks the unit securely junctions are silicone sealed. The 5/8 -24 threaded ring is fitted with an O-ring to without deforming the case. make a moisture proof connection. Cable is available in 10, 25, or 50 foot lengths. The PLUG MOUNT (see diagram below) allows 3/4 dia. cylindrical sensors to be mounted in thru-wall applications. The Plug Mounts 3/4-14 NPT DIMENSIONS In inches (mm) thread is installed into a threaded wall or casing. The sensor is then installed POLARIZED 3-PIN, 5/8 - 24 THREADED CONNECTOR through the plug mount. The sensor-to-target airgap is adjusted and the sensor is tightened into position by two 8-32 set screws. Tightening the ferrule nut CABLE CLAMP PIN WIRE COLOR compresses a teflon ferrule around the sensor providing an oil tight seal.
