SLOTTED OPTICAL SWITCHes

DESCRIPTION
The H21A SLOTTED OPTICAL SWITCH is a gallium arsenide light emitting diode coupled to a silicon phototransistor in plastic housing. The packaging system is designed to optimize the mechanical resolution, coupling efficiency, ambient light rejection, cost and reliability. The gap in the housing provides a means of interrupting the signal with an opaque material, SWITCHing the
output from an “ON” to an “OFF” state.

FEATURES
• Opaque housing
• Low cost
• .035” apertures
• High IC(ON)

Description
Each OPB615, OPB625 and OPB665 series SLOTTED OPTICAL SWITCH consists of an 890 nm, infrared Light Emitting Diode(LED) and a monolithic integrated circuit that incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single silicon chip. OPB665 offers two mounting options - no tabs (N) or two tabs(T).

Features:
● Non-contact SWITCHing
● PCBoard mounting
● Enhanced signal to noise ratio
● Choice of four Logical output options

Applications:
● Mechanical SWITCH replacement
● Speed indication (tachometer)
● Mechanical limit indication
● Edge sensing

Description:
The OPB816Z SLOTTED SWITCH consists of an infrared emitting diode and an NPN silicon phototransistor mounted in an opaque housing with clear windows for dust protection. SWITCHing of the phototransistor occurs whenever an opaque object passes through the slot.
The OPB816Z has an 0.61” (15.49 mm) deep slot allowing for a longer reach of the OPTICAL center line from the mounting plane. The phototransistor internal apertures are 0.10” x 0.06” (0.25 mm x 1.52 mm) on the sensor side (“S”) and 0.05” x 0.06” (1.27 mm x 1.52 mm) on the emitter side (“E”).

Features:
• 0.20” (5.1 mm) wide gap, 0.61” (15.5 mm) deep slot
• Wire length 24” (609 mm) minimum, 26 AWG
• Dust protection
• Two mounting tabs

Applications:
• Non-contact object sensing
• Assembly line automation
• Machine automation
• Equipment security
• Machine safety

SINGLE CHANNEL DARLINGTON SLOTTED INTERRUPTER SWITCH

Description
The OPB816 consists of an infrared emitting diode and an NPN silicon phototransistor mounted in an opaque housing with clear windows for dust protection. The deep slot allows for a longer reach of the OPTICAL center line from the mounting plane, .650” (16.51 mm).

Features
·.20”(5.08 mm) wide gap
·24”minimum, 26 AWG wire leads .86” (21.8 mm) deep slot
·Dust protection

Description
The OPB690 consists of an NPN phototransistor and an infrared emitting diode in a molded plastic housing. The phototransistor has an enhanced low current roll-off which improves contrast ratio and immunity to background irradiance. A lever arm actuated flag interrupts the light beam, SWITCHing the transistor output between states that can readily drive logic gates.
This SWITCH is designed to easily snap mount into a 0.037" ± 0.001" (0.94 mm) thick material with a rectangular opening of 0.320" ± 0.003" x 0.472" (8.13 mm x 11.99 mm) minimum. Insertion into the punched side of metal is recommended.
Customized lever arms and spring torques can be designed for specific applications.

Features
• Phototransistor output
• Mechanical SWITCH replacement
• 3-pin connector (Ho Tien L2561-03), Molex compatible connector 5102 series housing and 5103 series terminal
• Enhanced signal to noise ratio
