The Maxwell MS-1DA48 series is a high-performance, single-phase DC to AC solid state relay designed for reliable and efficient switching in demanding industrial environments. Featuring a wide control input range of 3.2–32VDC and a robust load voltage capacity of 24–480VAC, this panel-mount relay is engineered to seamlessly interface with microcontrollers, PLCs, and other low-voltage logic devices. It utilizes advanced zero-crossing trigger technology and incorporates a built-in RC snubber across all amperage ratings, ensuring noise-free operation and superior protection against transient voltage spikes. Housed in a compact, fire-retardant ABS enclosure and completely sealed with resin for maximum isolation, the MS-1DA4840 series guarantees exceptional durability and safety 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 Maxwell TT-501 Series is a robust and highly versatile threaded thermocouple temperature transmitter engineered for demanding industrial environments. Housed in a rugged, explosion-proof aluminum alloy enclosure, this transmitter delivers reliable and accurate temperature measurement across a wide range of process conditions. An integrated digital display provides clear, on-site readings, while the RS485 (Modbus RTU) communication output enables seamless integration into modern PLC-based control systems, SCADA networks, and building management systems. With its highly customizable design — featuring multiple thread options (M6, M8, 1/4 BSP, 1/4 NPT), a selection of premium probe materials (304, 316, and 310 stainless steel, brass, and aluminum), and a comprehensive range of lead wire materials — the TT-501 can be precisely configured to meet the exact requirements of any installation. Both grounded and ungrounded junction configurations are available, offering a choice between faster thermal response and electrical isolation to suit the specific demands of each application.

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.
