Banner LTBs are ergonomically designed to eliminate the hand, wrist, and arm stresses associated with mechanical push buttons. They require absolutely no physical pressure to operate. LED indicators light for "power on" and "output activated". LTBs are highly resistant to EMI, RFI, and ambient light interference, and are constructed from black polysulfone (or red Lexan[®] ) and VALOX[® ] for reliability in industrial environments. The 30-mm threaded base provides easy mounting, and LTBs are easily retrofitted to existing machines. See the listings on pages 2 and 3 for available models. **==> picture [149 x 154] intentionally omitted <==** **----- Start of picture text -----**

## **Specifications** **Supply Voltage:** 105 to 130V ac or 210 to 250V ac, depending upon model. See listings of available models, pages 2 and 3. **Output Configuration:** All models have SPDT electromechanical relay (one N.O. contact, one N.C. contact). **Output Rating:** _Maximum voltage_ is 250V ac or 30V dc. _Maximum current_ 7 amps (resistive load), 1 HP max. _Minimum load_ .05 watts (dc), .05VA (ac). _Mechanical life of relay_ 50,000,000 operations (min.). _Electrical life of relay_ 100,000 operations (min.) at full resistive load. _Transient suppression is recommended when switching inductive loads._ **Ambient Light Immunity:** 120,000 lux (direct sunlight). **EMI/RFI Immunity:** The OPTO-TOUCH is highly resistant to both single and mixed EMI and RFI noise sources. **Operating Temperature Range:** -20 to +50 ° C (-4 to +122 ° F). **Indicator LEDs:** Two indicator LEDs. One lights when power is "on"; the other lights when the infrared sensing beam is interrupted. ## **Construction:** Black polysulfone or red Lexan[® ] upper housing and fiber-reinforced VALOX[®] base. Electronics fully epoxy-encapsulated. Totally sealed, non-metallic enclosure. The LTB's threaded base has M30 x 1,5 external threads and 1/2" NPSM internal threads. The base requires a 1-3/16" diameter mounting hole (fits most standard automotive-size "jumbo" legend plates and oiltight pushbutton holes). OPTO-TOUCH LTBs are rated NEMA 1, 3, 4, 4X, 12, and 13. **Cable:** _Quick-disconnect (QD) models_ require model MBCC-512 5-conductor mini-type cable (p/n 25496), purchased separately. QD cables are 12 feet long. _Models with attached cable_ (non-QD models) are supplied with 6 feet of PVC-jacketed, 22 AWG 5-conductor cable. **Environmental Considerations** (models with **polysulfone** housing): _Prolonged exposure of the OPTO-TOUCH to_ _**direct outdoor sunlight**_ will cause embrittlement of the polysulfone housing. Window glass effectively filters longer wavelength ultraviolet and provides excellent protection from sunlight. Contact the factory Application Engineering Department regarding outdoor applications. _Clean periodically_ using a mild soap solution and a soft cloth. _Avoid the following substances,_ as they will attack polysulfone to varying degrees: esters, ketones, aromatic hydrocarbons, chlorinated hydrocarbons, and strong alkaline materials. **Environmental Considerations** (models with **Lexan[®]** housing): _Prolonged exposure of the OPTO-TOUCH to_ _**hot water and moist high-temperature environments**_ above 150 ° F (66 ° C) should be avoided. _**Aromatic hydrocarbons**_ (such as xylene and toluene), _**halogenated hydrocarbons,**_ and _**strong alkalis**_ should be avoided. Clean periodically using mild soap solution and a soft cloth. ## **Read all WARNINGs carefully.** **==> picture [7 x 13] intentionally omitted <==** **----- Start of picture text -----**

**WARNING. Banner OPTO-TOUCH™ LTB Series Optical Touch Buttons are intended as general-** ! **purpose initiators, and are** _**not**_ **safety devices.** Like most solid-state devices, they are as equally likely to fail in the conducting ("on") state as in the non-conducting ("off") state. If OPTO-TOUCH Optical Touch Buttons are used to initiate machines or operations in which false operation of an Optical Touch Button could be dangerous, _pointof-operation guarding devices_ or related safety controls must be installed and maintained to meet all appropriate OSHA regulations and ANSI B11 machine safety standards. NOTE: In addition to the standards and regulations mentioned above, there are numerous regulations and machine safety standards that apply to specific industries. For assistance in obtaining copies of any of these standards, contact Banner at the address and or numbers listed at the bottom of page 4.

## **OPTO-TOUCH LTB Mounting Hole Information** The OPTO-TOUCH has a 30 millimeter threaded base which fits directly into a standard mounting hole for an oiltight push button. A lock ring, supplied with each OPTO-TOUCH, may be used to prevent switch rotation. The mounting hole details shown at the right are used for the OPTOTOUCH and also for standard oiltight push buttons and their legend plates. The drawing at the far right shows how to approximate the keyway using a drill hole. ## **Model SMB30S Swivel Mount Bracket** **The model SMB30S swivel-mount bracket** (p/n 33204) is a versatile means for mounting a Banner OPTO-TOUCH Optical Touch Button. The SMB30S lets you _ergonomically position_ the OPTO-TOUCH on most machinery for maximum operator comfort and convenience. The SMB30S mounts by its base. Its swivel ball locks snugly in place when its two clamping bolts are tightened. Bracket material is black VALOX[®] . Hardware is stainless steel, and mounting bolts are included. The photo at the right shows a model SMB30S bracket with an OPTO-TOUCH attached. **==> picture [44 x 9] intentionally omitted <==** **----- Start of picture text -----**

**Never use an OPTO-TOUCH Optical Touch Button as an actuator in an emergency stop (E-Stop) circuit.** E-Stop actuators must be purely mechanical devices that require no power to operate. OPTO-TOUCH Optical Touch Buttons require power to operate and **must not be used as E-Stop actuators under any circumstances.** 2 ## **LTB Series** _**Alternate Action**_ **OPTO-TOUCH** ## **Dimensions** ## **OPTO-TOUCH Field Covers** OPTO-TOUCH Field Covers (see drawing, below) are designed to prevent inadvertent activation of OPTO-TOUCHs due to objects (loose clothing, debris, etc.) which might accidentally block the sensing beam. Field covers are constructed of rugged polycarbonate-PET polyester blend, which is capable of absorbing high impacts, even at low temperatures. This material is highly resistant to abrasion and to damage by most chemicals. Every OPTO-TOUCH is supplied with a black field cover, as standard. Field covers are available separately in four colors, which can be used to differentiate touch button functions when several touch buttons are in use: **Black** OTC-1-BK, p/n 30221 **Yellow** OTC-1-YW, p/n 30978 **Red** OTC-1-RD, p/n 30977 **Green** OTC-1-GN, p/n 30979 Model shown has built-in, attached cable.

A field cover has been supplied with this OTB. It should be installed, as shown in the drawing above, to minimize the possibility of unintended switch operation. If this cover is missing or has become lost or damaged, contact Banner immediately at (612) 544-3164 for a no-charge replacement. **Ordering Information:** OPTO-TOUCH Optical Touch Buttons are shipped with a black field cover, as standard. A black field cover will be received if the OPTO-TOUCH is ordered by its model number (only). Red, yellow, or green field cover may be specified instead by ordering the OPTO-TOUCH using the appropriate 5-digit part number from the table, below. Field covers may also be ordered separately (above). **==> picture [364 x 210] intentionally omitted <==** **----- Start of picture text -----**
