VLU-BM 95 eries sensor features 95 eries ensors Description VLU-BM 95 eries sensors are rugged, self-contained photoelectric sensors designed for especially demanding industrial applications where economy, performance, and durability are important. They feature PDT (single-pole, double-throw, form ) electromechanical relay output and operate from a variety of supply voltages. Powerful, modulated LD light sources provide a wide sensing range. The sensors are extremely robust; being totally epoxy-encapsulated, they are highly resistant to shock, vibration, moisture and corrosion. 95 eries sensors may be mounted from either the front or the rear, using the two through-mount holes, or by their threaded base (mounting nut supplied), making them ideal for conveyor and other production line applications. The easy-to-see top-mounted red LD indicator (see Figure ) simplifies alignment and system monitoring. t lights whenever the sensor sees its own modulated light source. Turn the ensitivity control (on the sensor back panel) clockwise to increase gain. Light or dark operate is selected by connecting the appropriate output relay contact to the circuit under control (see Hookups, page 7). Fiber Optic Models Banner offers a complete line of both plastic and glass fiber optic assemblies to fit VLU-BM 95 eries fiber optic model sensors. Glass fiber assemblies are recommended for environments with high temperatures, extreme moisture and corrosive materials; they are not recommended for applications requiring bending or repeated flexing of fibers. Plastic fiber optics are an economical alternative for piping photoelectric sensing light into and out of confined areas where the environmental conditions allow, and they can withstand repeated flexing. Banner plastic fiber optic assemblies are available in several core sizes; the highest excess gain will be obtained with the larger fiber cores. tandard plastic fiber optic assemblies are unterminated on the control (sensor) end. These assemblies are approximately 2 m (6 ) long and may be used as-is, or may be cut to length as needed, using the supplied fiber cutter. utting and installation instructions also are included with the fiber assembly. Both plastic and glass fibers are offered in individual and bifurcated styles. ndividual fibers are used in pairs in the opposed sensing mode; one fiber transmits the light to the sensing location, while the other fiber returns the received light to the sensor. Bifurcated plastic fiber assemblies are two-way fibers, having a single sensing end that both emits and receives light and dual control (sensor) ends, which attach separately to the sensor. Fiber optic assemblies are available with a wide variety of sensing end styles. Refer to your current Banner Photoelectric atalog for a full selection. *OT: 9 m (3') cables are available by adding suffix W/3 to the model number of any cabled sensor (e.g. - MW95FP W/3). model with a QD connector requires an accessory mating cable. ee page 8 for more information.
