Square Force-Sensitive Resistor FSR 400 series is part of the single zone Force Sensing Resistor family. The model 406 FSR is a single-zone Force Sensing Resistor optimized for use in human touch control of electronic devices such as automotive electronics, medical systems, and in industrial and robotics applications. FSRs are two-wire devices. They are robust polymer thick film (PTF) sensors that exhibit a decrease in resistance with increase in force applied to the surface of the sensor. It has a 39.6mm square active area and is available in 4 connection options. This FSR 406 force sensor will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1M?. This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR. Also check Spectra Symbol 12.7 mm Circular Force sensor . It is a force-sensitive resistor with a round, 0.5? diameter sensing area. The resistance of this FSR varies based on the amount of pressure applied to its sensing area. When no pressure is applied, its resistance is larger than 1M?. The FSR can sense forces in the range of 100g to 10kg.

Square shaped Force Sensor Square-shaped force sensors are usually made of a spring element, such as a metal beam, diaphragm, or cylinder, that is deformed when a force is applied to it. This Force Sensor has a sensing area of 1.75 x 1.5?, sensing area and it will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1M?. This Pressure Sensor can sense force anywhere in the range of 100g-10kg and can be easily integrated with Microcontrollers, Arduino Boards, Raspberry Pi, etc. using Analog to Digital converters (ADC).

SSR-40DD DC 3-32V Input to DC 5-200V Solid state relay This is DC To DC SSR-40DD 40A Solid State Relay Module offers an input of 3V-32V DC with an output voltage of 5V -200VDC at an output current of 40A. A solid-state relay (SSR) is simply an IC that functions as a mechanical relay. The only difference between this SSR with the mechanical relay is that there is no moving contact in a Solid-State Relay. This SSR allows us to control high-voltage AC loads from lower voltage DC control circuitry. This is achieved by using infrared light as the ‘contact,’. In short, a solid-state relay is just an IR LED and a photometric enclosed into a little box. Thus we make use of the Phototriac coupler to turn it ON and OFF. Solid-state relays offer numerous advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, as there are no moving contacts, solid-state relays switched much faster and for much longer periods without wearing out. Each one of these relays is designed with four screw terminals for use with ring or fork connectors. And enclosed in a plastic cover that slides over the top of the relay to protect the terminals. This Solid State Relay module features long service life and high reliability with reduced electromagnetic interference. Moreover, its compact size design offers users maximum simplicity. Also, read our blog on What is Relay in Electrical explaining what is it, how does it works, its construction, different types of relays, and applications. Features: Input Voltage: 3-32V DC Output Voltage: 5-200V DC Load Current: 40A Control Type: DC to DC Switching Speed: High switching speed with no noise or sparks Durability: No mechanical parts, leading to high reliability and long life Resistance: Resistant to vibration and moisture Size: Compact size for easy integration into various systems Heat Dissipation: Requires proper heat dissipation to ensure longevity Applications: Industrial Automation: Used in controlling machinery and equipment in automated production lines. Temperature Control Systems: Ideal for switching heating elements in temperature control systems. DC Motor Control: Suitable for controlling DC motors in various applications, including robotics and conveyor systems. Lighting Control: Can be used to control lighting systems, including stage lighting and traffic lights. Pumps and Valves: Used in controlling DC pumps and solenoid valves in fluid handling systems. Home Automation: Useful in home automation projects for controlling various DC-powered devices.
