The PT100-3 is a widely used probe-type Platinum Resistance Thermometer (PT100 RTD) engineered for reliable and accurate temperature measurement in harsh industrial environments. The sensor integrates a rugged Form B connection box that protects internal wiring from dust, moisture, and mechanical damage, making it especially well suited for outdoor installations, chemical plants, and other demanding process environments. Compliant with EN 60751, the PT100-3 delivers a broad measurement range of −70 °C to +300 °C with high stability and repeatability. The sensor is compatible with a variety of standard process fittings — including 1/2 NPT, 1/2 BSP, 3/4 NPT, and M16 — enabling straightforward integration into existing pipelines and equipment. Probe diameter and length are fully customisable, allowing the PT100-3 to be tailored to virtually any installation requirement.

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 JX-1DA48 (black flip-cover housing) and KT-1DA48 (grey housing) are single-phase, DC-controlled AC solid state relays designed as direct-fit, cost-effective alternatives to Omron G3NA-style SSRs. Both variants share identical electrical specifications and the same compact physical footprint, differing only in housing style and colour. Accepting a DC control voltage of 3.2–32 VDC, these relays are directly compatible with PLC transistor outputs, microcontroller I/O, and standard industrial DC control signals. The AC load side supports 24–480 VAC at 50/60 Hz, covering 110 V, 220 V, 380 V, and 480 V systems worldwide. Load current ratings of 10 A, 25 A, and 40 A are available, with all three ratings sharing the same physical dimensions for easy interchangeability. Zero-crossing trigger technology ensures switching occurs at the natural zero-crossing point of the AC waveform, minimising EMI and extending load service life. A built-in RC snubber circuit is incorporated across all three current ratings, providing additional protection against voltage transients without requiring external components. The 10 A, 25 A, and 40 A models all use a TRIAC output stage, offering reliable bidirectional switching. An LED status indicator provides instant visual confirmation of relay activation. The panel-mount housing includes a protective cover (JX-1DA48) for added terminal protection. Private label and custom logo laser printing are available on request.
