No Blind Spot Safety Light Curtain (17.2*30mm)

● Reaction time of less than 15 milliseconds

● Capable of blocking 99.99% of interfering signals

● Self-check, overload protection, polarity, and short circuit

The emitter and the receiver are the two basic components of the safety light curtain. Infrared rays are released by the transmitter, and the receiver absorbs them to create a light curtain. The light receiver reacts instantly through the internal control circuit when an object enters the light curtain, stopping or alarming the apparatus (like a punch) to safeguard the operator. safety and guarantee the equipment's regular, secure operation.

Product characteristics

On one side of the light curtain, there are several infrared transmitting tubes spaced equally apart, and on the opposite side, there are an equal number of infrared reception tubes placed similarly. Every infrared transmission tube is placed in a straight line with a matching infrared receiving tube. The modulated signal, or light signal, emitted by the infrared transmitting tube can effectively reach the infrared receiving tube when there are no obstructions in the path of the tubes on the same straight line. Light curtain sensors are commonly used in industrial and manufacturing settings to detect the presence or absence of objects in a specific area. The sensor emits modulated infrared light signals, and when no objects interrupt the light path, the signals reach the receiving tubes, causing the internal circuits to output low levels. When an object does pass through the light curtain, it interrupts the light signals, causing a change in the internal circuit status, which can be analyzed to detect the presence of the object.

Overall, light curtain sensors are an effective and versatile way to detect objects in a wide range of industrial applications, including machine safety, material handling, and quality control.

Safety Light Curtain Selection Guide

Step 1: Find the safety light curtain's optical axis spacing, or resolution.

1. The operator's operation and particular surroundings must be taken into account. The optical axis spacing should be somewhat narrow if the machine equipment is a paper cutter since the operator visits the risky area more often and is quite close to it, making accidents more likely to occur. Light curtain (eg: 10mm). To safeguard your fingers, think about using light curtains.

2. In the same way, if the frequency of entering the dangerous area is relatively reduced or the distance is increased, you can choose to protect the palm (20-30mm). 3. A light curtain with a little greater distance (40mm) can be used to shield the arm from the harmful area.

4. The light curtain's highest limit is to safeguard human health. The light curtain with the greatest distance (either 80 or 200mm) is yours to select.

Step 2: Select the light curtain's protection height.

Actual measurements can be used to establish conclusions, and the determination should be made in accordance with the particular machine and equipment. Keep an eye out for the distinction between the safety light curtain's protective height and height. [The safety light curtain's height is its overall appearance; its protection height is its effective protection range when it is in operation; that is, its effective protection height is equal to its optical axis spacing times the total number of optical axes.]

Step 3: Choose the anti-reflection distance for the light curtain.

The distance between the transmitter and the receiver is known as the through-beam distance. It should be determined according to the actual situation of the machine and equipment, so that a more suitable light curtain can be selected. After determining the shooting distance, the length of the cable should also be considered.

Step 4: Ascertain the light curtain signal's output kind.

It needs to be ascertained using the safety light curtain's signal output mechanism. Some light curtains may not match the signals output by the machine equipment, which requires the use of a controller.

Step 5: Bracket selection

Choose L-shaped bracket or base rotating bracket according to your needs.
