The Keyence SL-V40H is a high-performance safety light curtain engineered to deliver reliable machine guarding and operator protection in industrial environments. As part of Keyence’s SL-V Series, it combines accurate detection capability, flexible installation options, and long-lasting optical technology, making it an ideal safety solution for manufacturers aiming to protect both personnel and productivity.

With a detection capability of ‚àö‚àè25 mm (0.98″), the SL-V40H ensures dependable detection of small objects such as hands or tools entering hazardous zones. This fine level of precision is particularly important for machine guarding applications, as it reduces risks associated with operator exposure to dangerous moving parts. It also provides reliable monitoring for production lines where both safety and product flow must be maintained without compromise.

The device is designed with a 20 mm beam axis spacing and ‚àö‚àè5 mm (0.20″) lens diameter, ensuring efficient beam coverage across the protected zone. This dense yet practical beam layout minimises the possibility of blind spots while providing strong and consistent detection performance. By creating a continuous detection grid, the SL-V40H enables thorough monitoring in environments ranging from compact assembly machines to expansive conveyor systems.

The light curtain supports a working distance of 0.1 to 9 m, offering remarkable flexibility for a variety of applications. This broad range makes it suitable for both close-range equipment guarding and larger installations requiring extended coverage. Such adaptability allows manufacturers to standardise safety measures across diverse equipment, streamlining system design and simplifying maintenance.

To further support ease of use, the SL-V40H allows for an effective aperture angle of up to ¬¨¬±2.5¬¨‚àû when installed at distances of 3 m (98.23′) or more. This tolerance simplifies alignment during setup, reducing installation time and minimising errors. It also accommodates minor shifts or vibrations in equipment over time, ensuring consistent long-term performance without requiring frequent realignments.

The SL-V40H employs an infrared LED light source at 850 nm, delivering reliable detection that is resistant to interference from ambient light. Infrared LEDs are not only highly stable but also provide long service life, reducing the need for maintenance and keeping downtime to a minimum. This makes the unit both dependable and cost-efficient over extended use.

Applications for the SL-V40H span multiple industries, including automotive manufacturing, electronics production, packaging, and general industrial machinery. It helps safeguard operators while supporting compliance with strict safety standards, allowing companies to maintain high productivity levels alongside reliable protection.

In summary, the Keyence SL-V40H offers dependable protection with its ‚àö‚àè25 mm detection capability, optimised beam layout, long working range, and durable infrared LED technology. Built for flexibility, accuracy, and long-term reliability, it is a trusted choice for industrial environments where safety and efficiency must go hand in hand.
