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.

Heatsinks for 3 phase SSR, compatible with 10A/25A solid state relay, it's a radiator to help the SSR cool down while operating.

The COMCONNECT CST-A-PT-2MS is a high-precision RTD temperature sensor designed for industrial and laboratory applications ranging from -20°C to 400°C. It features a PT100 Class A sensing element for superior accuracy and a 3-wire configuration to eliminate lead resistance errors. The sensor comes in a rugged waterproof enclosure (50.3×65.6×55.9mm) and a 2-meter shielded silicone cable (red, 3×7×0.15mm) for reliable signal transmission in harsh environments. The stainless steel probe (5×50mm) ensures fast thermal response. Customization options are available for probe dimensions, box size, and cable types.

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.
