The Maxwell MS-1AA4840 series is a robust and highly reliable single-phase AC to AC solid state relay engineered for demanding industrial control applications. Designed with a wide control input range of 90–280VAC and a versatile load voltage capacity of 24–480VAC, this panel-mount relay ensures seamless integration into diverse electrical systems operating at 50/60Hz. It features advanced zero-crossing trigger technology and a built-in RC snubber across all amperage ratings, providing exceptional protection against transient voltage spikes and ensuring noise-free, fast-response operation. Housed in a compact, fire-retardant ABS enclosure and completely sealed with resin for maximum isolation, the MS-1AA4840 series guarantees long-lasting performance in harsh environments. With load current options ranging from 10A to 120A, it is the ideal solution for precise control in heating systems, plastic machinery, HVAC, and various automated industrial processes. All models comply with CE, CCC, and RoHS standards.

The NTC10K Series is a compact, high-precision Negative Temperature Coefficient (NTC) thermistor temperature sensor housed in a rugged stainless steel M8 screw-body probe. Designed for direct installation into threaded ports on pipework, tanks, heat exchangers, and machinery, this sensor delivers accurate, low-cost temperature measurement across a wide operating range without the need for signal conditioning or cold-junction compensation.At the heart of the sensor is a precision NTC thermistor element with a nominal resistance of 10 kΩ at 25 °C and a B-value (B25/100) of 3950 K ± 1%. The thermistor element is encapsulated within a 4 mm diameter stainless steel probe, sealed with high-temperature epoxy resin to ensure moisture ingress protection. The M8 threaded body incorporates a high-temperature silicone gasket to provide a leak-proof seal when installed into a threaded port. A 150 mm flat silicone lead wire terminates in a standard 2-pin SMP (Micro-Fit style) connector for fast, tool-free connection to the host system.The NTC10K series is fully compatible with Maxwell's range of temperature controllers, as well as third-party controllers, HVAC control boards, and microcontroller-based systems that accept a passive NTC thermistor input. The sensor's small probe diameter, short lead wire, and plug-and-play connector make it an ideal drop-in component for OEM equipment manufacturers and system integrators.

The PT100-14 is a bolt-on PT100 Platinum Resistance Thermometer designed for direct surface temperature measurement. The sensor element is integrated into a ring (eye) terminal lug that is bolted or screwed directly onto the surface to be measured — such as a motor casing, heat sink, pipe outer wall, bearing housing, or structural component — ensuring intimate thermal contact without the need for a thermowell, probe pocket, or adhesive. This makes the PT100-14 an exceptionally convenient and cost-effective solution wherever surface temperature monitoring is required. The ring terminal inner diameter is available in 6 mm or 8 mm as standard, and can be customised to match any bolt or screw size specified by the customer. The sensor is supplied with a stainless steel braided cable for mechanical protection and EMI shielding, and the lead wire material is fully selectable from stainless steel braid, silicone, fiberglass, or Teflon to suit the thermal and chemical conditions of the installation environment. Standard cable lengths are 2 m, 3 m, and 5 m, with custom lengths available on request. The sensor is available in temperature ranges up to 100 °C, 200 °C, or 300 °C.

The PT100-15 is a flexible, PFA-insulated RTD sensor engineered for precise temperature measurement in highly corrosive environments. Both the probe and cable are fully encapsulated in fluoropolymer (PFA), offering exceptional resistance to saline solutions, strong acids, caustic fluids, and electroplating baths. Designed for continuous immersion, the sensor’s flexibility allows for easy installation in confined or complex spaces, ensuring reliable performance in demanding industrial applications.

The TC-K14B is a fast-response K-type thermocouple engineered for applications where rapid, accurate temperature measurement is essential. Unlike conventional sheathed thermocouples, the TC-K14B features an exposed welded-bead junction with minimal thermal mass, enabling it to detect temperature changes within fractions of a second. This makes it the preferred choice for dynamic temperature monitoring tasks in research, testing, and industrial quality control environments. The sensor is constructed from a fine-gauge Chromel-Alumel (K-type) thermocouple wire pair, twisted together and insulated with a flexible fiberglass braid. The green-and-white color coding of the lead wire follows the international K-type thermocouple standard, providing clear polarity identification. The fiberglass insulation offers excellent thermal resistance and flexibility, allowing the sensor to be routed through confined spaces and around complex geometries without risk of insulation damage. At the instrument end, the TC-K14B is fitted with a standard miniature K-type quick-disconnect connector (green housing, labeled 'K NiCr+ / NiAl−'), which is compatible with a wide range of handheld thermometers, data loggers, and temperature indicators that accept the IEC 60584 / ANSI miniature thermocouple connector standard. The plug-and-play design eliminates the need for field wiring, enabling rapid deployment and sensor replacement without tools or specialist knowledge. The lead wire length is fully customizable, making the TC-K14B adaptable to installations where the measurement point is located at a significant distance from the instrument. As part of the PIDMaxWell range of temperature measurement solutions, the TC-K14B is designed to integrate seamlessly with PIDMaxWell PID temperature controllers, temperature transmitters, and compatible third-party instrumentation.
