Data Sheet - OPTEK Technology

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.

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.
