Excessive Voltage SMD Reed Relays for Enhanced Efficiency


Pickering Electronics, a famend chief in high-performance reed relays, has launched its groundbreaking Sequence 219, marking the corporate’s foray into high-voltage floor mount reed relays. The announcement was made at Productronica, the premier commerce honest for the electronics manufacturing business.

Designed for versatility, the Sequence 219 floor mount reed relays are available numerous bundle sorts with equivalent sizes however differing pin positions. These relays boast the potential to change as much as a formidable 1000V, providing configurations in 1 Type A (SPST), 2 Type A (DPST), and 1 Type B (SPNC). The swap stand-off reaches as much as 3000V, and switch-coil isolation achieves a exceptional 5000V stand-off.

The Sequence 219 is poised to excel in a mess of excessive voltage purposes, together with however not restricted to combined sign semiconductor testers, medical tools testing, electrical automobile (EV) cost level testing, and monitoring photo voltaic cell photovoltaic effectivity.

Inside this progressive collection, all contact configurations can be found with three coil voltages: 3V, 5V, or 12V. The swap stand-off capabilities fluctuate, reaching as much as 1.5kV within the 2 Type A bundle, 2kV in 1 Type B, and 3kV within the 1 Type A bundle. Change-coil isolation stands at a formidable 5kV stand-off in 1 Type A and 1 Type B sorts. The relays help switching as much as 0.7A and 10W, and their operational temperature vary spans from -40°C to +105°C.

A notable characteristic of the Sequence 219 is the inclusion of a diode possibility in all half numbers. Suppression diodes are strategically positioned inside the relay to safeguard the machine driving the relay coil in opposition to again electromotive drive (emf), which may happen when the present stream to the coil is interrupted. This preventative measure ensures the safety of different elements on a PCB board, such because the coil drive.

Robert King, Product Improvement Supervisor at Pickering Electronics, emphasised the distinctiveness of the Sequence 219, stating, “Solely Pickering makes floor mount excessive voltage relays with 2 Type A and 1 Type B packages.” The two Type A configuration optimizes board area by offering two switches in the identical footprint, whereas the 1 Type B possibility presents a usually closed relay, a characteristic not available elsewhere available in the market.

True to Pickering’s dedication to buyer satisfaction, the Sequence 219 Reed Relay is obtainable with numerous customary construct choices to tailor it to particular purposes. Moreover, for necessities past customary choices, the corporate offers a custom-made reed relay service to fulfill customers’ particular wants.

Persevering with the custom of excellence seen in different Pickering relays, the brand new 219 Sequence excessive voltage reed relays make use of top-tier instrument-grade switches with applicable swap blade coatings to fulfill the calls for of various currents and voltages. One other noteworthy innovation is the incorporation of SoftCenter know-how, minimizing inner stresses on the reed swap, thereby extending its life and guaranteeing contact resistance stability. The usage of magnetic Mu-Steel shielding and electrostatic screening additional enhances reliability by stopping defective operation.
