OPTO-TOUCHTM OTB Series Momentary Action Optical Touch Buttons Banner Optical Touch Buttons are touch-activated photoelectric switches designed to replace capacitive touch switches and mechanical push buttons. The OPTO-TOUCH's SPDT electromechanical relay or solid-state output (depending upon model) is activated for as long as a finger, introduced into the "touch area" (yoke) of the switch, interrupts the OPTO-TOUCH's infrared sensing beam. OTB Series Momentary Action Optical Touch Button (QD model shown) Banner Optical Touch Buttons 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". All models are highly resistant to EMI, RFI, and ambient light interference. OTBs have either a black polysulfone (or red Lexan(R)) upper housing and VALOX(R) base. Lexan(R) models have the letter "L" in their model number suffix. Environmental considerations for use of the two types differ; see specifications below. The 30mm threaded base on all models provides easy mounting, and Banner Optical Touch Buttons are easily retrofitted to existing machines. See pages 2 and 5 for model listings.

Banner OPTO-TOUCHTM OTB and OTBL 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, point-of-operation guarding devices or related safety controls must be installed and maintained to meet all appropriate OSHA regulations and ANSI B11 machine safety standards.

Optical touch buttons (OTBs) provide an ergonomic (stress-free) alternative to conventional mechanical push buttons used as actuators in two-hand trip controls. OSHA Requirement for Anti-tiedown Control Use of OTBs for two-hand trip machine actuation must include "anti-tiedown" control to prevent any means of defeating one or both actuators to create a one-hand trip. Federal law mandates the use of anti-tiedown control when two-hand trip actuators are used for cycle initiation of a single stroke part revolution clutched mechanical power press. OSHA Code of Federal Regulation, 7-1-92 Edition, CFR Title 29, Part 1910.217 (b) (6) (i) states: "A two-hand trip shall have the individual operator's hand controls protected against unintentional operation and have the individual operator's hand controls arranged by design and construction and/or separation to require the use of both hands to trip the press and use a control arrangement requiring concurrent operation of the individual operator's hand controls." Concurrent or "synchronous" actuation of two-hand trips is the most popular approach to anti-tiedown control. European Standard prEN 574, titled "Safety of Machinery - Two-handed Control Device", defines synchronous actuation as follows: "6.7 Synchronous actuations In synchronous actuation an output signal shall be generated only when both control actuating devices are actuated - in a time which is less than or equal to 0.5 seconds... ... If the control actuating devices are not actuated synchronously the output signal shall be prevented and it shall be necessary to release both control actuating devices and to reinitiate both input signals." WARNING ! ! In the United States, the functions that a two-hand control device is intended to perform are regulated by the Occupational Safety and Health Administration (OSHA). Whether or not any particular two-hand control system installation meets all applicable OSHA requirements depends upon the details of how the two-hand control device is applied, installed, operated, and maintained. When properly installed, a two-hand control device using OPTO-TOUCH OTB Series Optical Touch Buttons can provide protection only for the hands of the machine operator, and is not a point of operation personnel guarding device, as defined by OSHA regulations. It is necessary to install point of operation guarding devices, such as safety light curtains and/or hard guards, to protect personnel from dangerous machine motion. WARNING! ! 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. OPTOTOUCH Optical Touch Buttons require power to operate and must not be used as E-Stop actuators under any circumstances. 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 or numbers listed at the bottom of page 6. 4 Important Application Information Prevention of False Actuation Any anti-tiedown control must be designed to prevent accidental actuation. Anti-tiedown circutry must be designed to ignore false input signals. False signals include (but are not limited to) voltage transients, contact "bounce", and EMI or RFI "noise". If a PLC or any other solid-state controller is used to provide anti-tiedown, the design must assure that short duration signals (typically any signals less than a few milliseconds) are ignored. There are several manufacturers of anti-tiedown logic modules which include circuitry to minimize the possibility of false actuation. Definitions: Two-hand Trip (Control): A control that requires the operation of two separate control actuating devices by a machine operator's hands for initiation of a machine cycle. Anti-tiedown (Control): A two-hand trip control configured so that both of the operator's hands must be removed and then reapplied to the control actuating devices to start another machine cycle. (Also called "anti-defeat" control.) Ordering Information: OPTO-TOUCH Optical Touch Buttons are shipped with a black field cover, as standard.
