Slotted Optical Switch OPB857Z Features: • Three wires for economy in electrical connection • Water resistant, no optical openings in upper plastic body • Internal narrow aperture for high motion resolution Description: OPB857Z is a non-contact optical switch with a NPN silicon phototransistor and infrared Light Emitting Diode (LED) which are mounted on opposite sides of a 0.150” ( 3.8 mm) wide slot. The device upper body is a single molded piece IR transparent plastic that is tinted to reduce ambient light interference and offers water resistance as well as dirt/dust protection. The phototransistor has a internal aperture that offers good optical resolution. LED emissions are near-infrared (850 – 940nm). Custom electrical, wire and cabling services are available. Contact your local representative or OPTEK for more information. Compliant to EU RoHS Directive 2002/95/EC. Applications: • Non-contact object sensing Assembly line automation Machine automation Equipment security Machine safety Wire Color Description Red Collector Brown Anode Black Common Notes: (1) Wire is 26AWG, UL Rated PVC insulation. (2) Ideal torque for bolt or screw 0,45 to 0,68 Nm ( 4 to 6 Lb-in ). (3) When using a thread lock compound, ND Industries ”ND Vibra-Tite® Formula 3” will avoid stress cracking plastic. (4) Plastic is soluble in chlorinated hydrocarbons and ketones. Methanol or isopropanol are recommended as cleaning agents.
