OPB620

## Slotted Optical Switch 

## OPB610, OPB611, OPB620, OPB621 

## **Features:** 

- Non-contact switching 

- Printed circuit board mounting 

- Enhanced signal to noise ratio 

- PIN photodiode sensor for high speed (OPB611, OPB621) 

- Lead centers:  0.275: (OPB61_) / 0.320” (OPB62_) 

## **Description:** 

The **OPB610** and **OPB620** slotted optical switches consist of an infrared emitting diode and an NPN silicon phototransistor with an enhanced low current roll-off to improve contrast ratio and immunity to background irradiance. 

The **OPB611, OPB621** slotted optical switch consists of an infrared emitting diode and a PIN photodiode with a polysulfone housing that is opaque to visible light, but transmissive to infrared.  The low tr/tf of the PIN photodiode is ideal for highspeed operation.  The sensitivity to ambient radiation is minimized. 

Custom electrical, wire and cabling and connectors are available.  Contact your local representative or OPTEK for more information.

Notes: 

(1) RMA flux is recommended.  Duration can be extended to 10 seconds maximum when flow soldering.  A maximum of 20 grams force may be applied to leads when soldering. (2) Derate linearly 1.33 mW/°C above 25 ° C. 

(3) Derate linearly 2.0 mW/°C above 25 ° C. 

(4) Plastic body is soluble in chlorinated hydrocarbons and keytones. It is recommended that a trial exposure to flux & cleaning chemicals is performed to ensure sensor is not damaged.
