TT Electronics OPB625 Slotted Opto Switch 10K Pull-up

The TT Electronics OPB625 Slotted Opto Switch is a 10K pull-up through-beam optical switch designed for precision non-contact sensing on printed circuit boards. It features an 890 nm infrared LED and a 10K pull-up output for direct integration into digital circuits.

Overview

The device combines an 890 nm infrared light-emitting diode (LED) with a monolithic integrated circuit that houses a photodiode, linear amplifier, and Schmitt trigger on a single silicon chip. This integrated design is intended to deliver reliable operation with an enhanced signal-to-noise ratio, supporting accurate detection in a range of environments.

Key Features

• Through-beam slotted optical sensing for detecting objects that pass through the slotted gap
• 10K pull-up output, available in buffered or inverted configurations
• TTI/LSTTL compatible and capable of driving up to 10 standard TTL loads
• Operating temperature range of -40°C to 100°C
• Power dissipation of 240 mW
• Acts as a direct replacement for mechanical switches, avoiding issues related to contact wear, bounce, and contamination

Applications

Suited to speed indication (tachometer), mechanical limit switching, and edge sensing in automated systems, the device provides precise detection of objects passing through its slotted gap.

Specifications

• Supply voltage: 4.5 V to 16 V DC
• Package: Module style for through-hole PCB mounting
• Dimensions: 33 mm (width) x 43 mm (height) x 15 mm (depth)
• Weight: 50 g

Choose the TT Electronics OPB625 Slotted Opto Switch for applications requiring a compact through-beam sensor with a 10K pull-up output and a wide operating temperature range.
