EN175301-803 (DIN 43650)

EN 175301-803 (DIN 43650 / ISO 4400) Solenoid Valve Connectors.

In2Connect’s robust molded connectors from HTP provide an innovative and cost effective solution to wiring DIN solenoid valves, featuring improved IP/NEMA ratings and better cable strain relief. We offer a range of conveniently packaged connectors for use with pneumatic and hydraulic valves in process control applications ~ used with pressure switches, level sensors, motors, limit switches, actuators



Industry standard, 2 and 3 contact, panel and cable mounting, vibration proof, gasket-sealed screw lock connectors. In2Connect offer forms A, B and C, all of which provide protection to IP 67 per IEC 60529. When correctly assembled with the gaskets and screws which complete the package, this ensures reliable performance when exposed to fluid jets and dust. They conform to DIN EN 175301-803 (formerly DIN 43650).

The three styles: Form A (27.5 x 27.5mm), Form B (28.5 x 21mm), and Form C (15.5 x 15.5mm), have 18 mm,11 mm, and 8 mm contact separations, respectively. Form B is commonly referred to as a “micro” connector, while Form C is often referred to as a “sub-micro.” Their black, grey or transparent body mouldings are suitable for ambient temperatures from -40 to + 125ºC and the screw type; snap-inserted, silver plated contacts are rated at 10 Amps max. Uniquely there is a double cable inlet grommet for Form A enabling the same connector to be used for both PG9 and PG11 cables. Right angled connectors can be purchased factory moulded to PVC or Polyurethane cables, these have solder connections. 1 and 2 metres lengths are standard, other lengths are available on request. ATEX Approved versions are available for Ex II 2GD applications.

DIN 43650 connectors are available with in-built electronic components in a host of protection circuit configurations; incorporating LED indicators, varistors, diodes for overvoltage protection, rectifiers etc. Voltage spike suppressing diodes do not have as much capacity to conduct large surges as varistors, but are not degraded by smaller surges and can provide high reliability and fast response time with a lower “clamping voltage”. Varistors degrade from repeated exposure to surges, have a higher “clamping voltage” so that leakage does not degrade the varistors and are generally used to protect line powered circuitry.

HTP connectors may also be customised
according to customer specifications. Preferred options with electronic components (preferred options in red):

Black or Grey bodies standard circuits: D0, V0, Z2, F0, R0
Transparent bodies standard circuits: L0, DL, VL, TL, FL, RL
Standard LED Colour: Red
