What are Terminals and Terminal blocks?

SNK Terminals are a type of industrial control terminal that is used in industrial automation, process control, and other applications. These terminals are designed to provide a secure and reliable connection between the user and the machine. They are typically used to control machinery, monitor production processes, and manage data. SNK Terminals are available in a wide range of sizes and configurations, allowing them to be used for many different types of applications.

Modular terminals are components that can be used to connect two or more devices together in a network. They are typically used to connect computers, servers, routers, switches, and other network devices. Modular terminals are often referred to as RJ-45 connectors because they use an 8-pin RJ-45 connector.

A terminal block is a type of electrical connector used to connect two or more wires together. It typically consists of a metal or plastic housing containing multiple terminals, which are the points at which the wires are connected. Terminal blocks are commonly used in industrial and commercial applications to provide a secure connection between electrical circuits.

Honeywell HLD Series: Hydrogen Leak Detection Sensor

The Hydrogen Leak Detector (HLD) Sensor uses the Honeywell advanced compensation algorithm to detect Hydrogen leaks in different applications. Designed with precision and reliability in mind, the HLD Sensor employs cutting-edge Thermal Conductivity Detection (TCD) technology to deliver lasting performance for many applications that require a highly accurate solution without manual intervention for ten years.

Its advanced detection capabilities ensure the identification of hydrogen leakage of 50 ppm or greater. Honeywell HLD Sensors can be utilized in many industries, such as automotive, industrial safety equipment, and residential power generators.

The incorporation of TCD technology in the HLD sensor offers several key advantages over catalytic beads. These benefits include greater accuracy, extended sensor lifespan, and enhanced resistance to chemical poisoning. With these advantages, the HLD sensor gives users the confidence that both lives and assets are well-protected.

Features:

High accuracy
CAN communication protocol (available) and voltage reading output (coming soon)
Thermal conductivity base sense element
Fast response time: <2 seconds
Short startup time: <1 second
Hydrogen sensing range: 0 % to 4 %
Operating temperature range: -40°C to 85°C [-40°F to 185°F]
50 H2 ppm resolution to detect low levels of H2 leakage
Resistant to chemical poisoning

Applications:
The HLD sensor is typically adjacent to the hydrogen storage tank, hydrogen gas piping, fuel cell, or vehicle cabin.

Hydrogen-powered heavy-duty trucks
Hydrogen-powered buses
Hydrogen-power generators
Hydrogen-powered automobiles
Hydrogen-powered construction equipment
Hydrogen-powered aircraft

Value to Customers:

Accurate: Designed for precise H2measurements to improve safety, allowing enhanced protection of assets and life
Reliable: TCD technology usage enables the customer to reduce downtime by eliminating false positives
Packaging: The IP67 seal allows the use of HLD even in numerous applications
