Indicates power with green LED and trigger with red LED
Ensures safety with protection circuitry
Operates in harsh conditions (-25 °C to 55 °C)
The Phidgets IR Beam Break Proximity Sensor - 50mm is a sophisticated through-beam sensor designed to detect the interruption of an infrared light beam. It is capable of triggering when an opaque object obstructs the space between its emitter and receiver. Additionally, it can detect transparent objects such as water droplets, provided the infrared beam is sufficiently disrupted and the sensitivity is appropriately adjusted. Sensitivity adjustments can be made using a flathead screwdriver on the top of the sensor.
This sensor features a 50mm wide sensing gap and is equipped with a green LED indicator that illuminates when the device is powered. A red LED indicator activates when the sensor is triggered, providing clear visual feedback of its operational status. The sensor is constructed from durable polycarbonate material and is designed to operate within a temperature range of -25 °C to 55 °C, with a humidity range of 35% to 85% RH.
The Phidgets IR Beam Break Proximity Sensor is engineered with protection circuitry to guard against reverse polarity and short-circuit conditions, ensuring reliable performance. It is suitable for use in various applications where precise detection of object presence or absence is required.

Shipping fees are non-refundable. Return shipping costs are the responsibility of the customer, except in cases of a product confirmed defective through RobotShop's troubleshooting process or of a verified shipping error by RobotShop.
Refunds are processed within 7 days after receipt and inspection of the returned item.
A $100 cleaning fee may apply to domestic robots returned in used or unclean condition.
A 20% restocking fee may apply to large-quantity returns of items ordered specifically for the customer from the manufacturer or not part of RobotShop's standard inventory.
Return Exceptions
The following products are not eligible for return or refund under this policy:
Used, damaged, or modified products — Items that show signs of use, wear, or alteration, making them unsuitable for resale.
Consumables — Use and wear-and-tear components, altered or depleted through use (e.g., batteries, belts, brushes, gears, filament, tires, disposable bags, lubricants, greases, waxes, etc.). Not eligible for return once opened or used.
Perishables — Goods liable to deteriorate or expire rapidly. Not eligible for return.
Sealed goods (health or hygiene) — Items sealed for health-protection or hygiene reasons (e.g., masks, gloves, odor-absorbing products). Not eligible for return once unsealed.
Build-it-yourself products and items requiring customer assembly — Including robots & kits, robot parts, and other products requiring assembly or soldering. Not eligible for return once assembled, soldered, or installed.
Digital Goods, Software, and Apps — Final sale only, due to licensing restrictions.
Clearance Items — Products identified as clearance or final sale, including end-of-life or discontinued items.
Custom-made, personalized, or special-order items — Products manufactured, configured, adapted, or built to the customer's own specifications and requirements.
On-Demand Items — Standard catalogue products not stocked by RobotShop and ordered specifically to fulfill a customer request.
While the same return policy applies, these orders require a separate contact process for returns.
