Product Overview

The OTBA5 is an OPTO-TOUCH momentary action Optical Touch Button with black field cover. The OTB series 27986 optical touch button is touch-activated photoelectric switch designed to replace capacitive touch switches and mechanical push buttons. The OPTO-TOUCHs SPDT electromechanical relay is activated for as long as a finger, introduced into the touch area (yoke) of the switch, interrupts the OPTO-TOUCHs infrared sensing beam. It is 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. Highly resistant to EMI, RFI and ambient light interference. OTBs has black polysulfone upper housing and VALOX® base. The 30mm threaded base provides easy mounting and easily retrofitted to existing machines.

on sensor 0TBA5

Need to know precisely how to wire to sensors together so one switch will not operate with out the other being presssed at the same time.
Also is there a synch module that can be used.

OTBA5 is a 120V ac, SPDT electromechanical relay output Photoelectric Sensor.

hence in order to connect 2 sensors you need to connect both SPDT connection in series i.e output of one SPDT relay should be connected in series to input of another SPDT relay
